Sending Pictures to the Computer

You can take two approaches to moving pictures from your camera memory card to your computer Connect the camera directly to USB symbol the computer. For this option, you need to dig out the USB cable that came in your camera box. The camera manual refers to the cable as the interface cable. Your computer must also have a free USB slot, or port, in techie talk. If you aren't sure what these gadgets look like, Figure 8-1 gives you a look. The little three-pronged icon you see on the plug and to...

Adjusting aperture and shutter speed

HBEff You can adjust aperture and shutter speed only in P, Tv, Av, and M exposure modes. In A-DEP mode, the camera forces you to use its selected exposure settings. You can, however, tweak the exposure by using the exposure-compensation feature discussed in the next section. To see the current exposure settings, start by pressing the shutter button halfway. The following activities then take place The exposure meter comes to life. If autofocus is enabled, focus is also set at this point. The...

Set Your Jpeg Image Quality

Your new T2i has a number of image quality settings to choose from, and depending on your needs, you can adjust them accordingly. Most people shoot with the JPEG option because it allows them to capture a large number of photos on their memory cards. The problem is that unless you understand how JPEG works, you might be degrading the quality of your images without realizing it. The JPEG format has been around since about 1994 and stands for Joint Photographic Experts Group. JPEG was developed...

Upgrading Your Firmware

If you're computer savvy, you might wonder how your EOS 40D is able to overwrite its own operating system that is, how can the existing firmware be used to load the new version on top of itself It's a little like lifting yourself by reaching down and pulling up on your bootstraps. Not ironically, that's almost exactly what happens At your command when you start the upgrade process , the 40D shifts into a special mode in which it is no longer operating from its firmware but, rather, from a small...

What Lenses Can You

How Align Camera Lens With Sensor

The previous section helped you sort out what lens you need to buy with your T2i (assuming you already didn't own any Canon lenses). Now, you're probably wondering what lenses can be added to your growing collection (trust me, it will grow). You need to know which lenses are suitable and, most importantly, which lenses are fully compatible with your Rebel T2i. With the Canon T2i, the compatibility issue is a simple one It accepts any lens with the EF or EF-S designation, with full availability...

Rotate the Main dial to select the shutter speed

Refer to Figure 7-7 to locate shutter speed on the Camera Settings display. After you select the shutter speed, the camera selects an aperture (f-stop) to match. What shutter speed you need depends on the speed at which your subject is moving, so some experimentation is needed. But generally speaking, 1 500 second should be plenty for all but the fastest subjects speeding hockey players like my subject, race cars, boats, and so on. For slower subjects, you can even go as low as 1 250 or 1 125...

Aperture setting fstop

Aperture is one of three exposure settings, all explained fully in Chapter 5. Depth of field increases as you stop down the aperture by choosing a higher f-stop number . For shallow depth of field, open the aperture by choosing a lower f-stop number . Figure 6-9 offers an example. Notice that the trees in the background are much more softly focused in the f 5.6 example than in the f 11 version. I snapped both images using the same focal length and camera-to-subject distance, so aperture is the...

Displaying Histograms

Canon Histogram

To view histograms on your screen, press the DISP button while an image is shown on the LCD. Keep pressing the button until the histogram s are shown. The display will cycle between several levels of information, including flashing highlights and two histograms. One histogram shows overall brightness levels Figure 4.24 , while the second type of histogram screen shows both brightness levels and levels for each of the red, green, and blue channels see Figure 4.25 . During histogram display,...

Adjusting Exposure with ISO Settings

Another way of adjusting exposures is by changing the ISO sensitivity setting. Sometimes photographers forget about this option, because the common practice is to set the ISO once for a particular shooting session (say, at ISO 100 or 200 for bright sunlight outdoors, or ISO 800 when shooting indoors) and then forget about ISO. The reason for that is that ISOs higher than ISO 100 or 200 are seen as bad or necessary evils. However, changing the ISO is a valid way of adjusting exposure settings,...

Canon EOS Digital Rebel XTi Roadmap

Cannon Rebel Xti Camera Settings

It's time for you to get to know your Canon EOS Digital Rebel XTi up close. Unfortunately, there are so many buttons and dials and knobs on this camera that many new owners especially those coming to the XTi from point-and-shoot models find the array of controls bewildering. What you really need is a roadmap, showing you where everything is and how it's used. Unfortunately, the diagrams provided in the XTi's manual have more resemblance to a world globe than a roadmap everything is there in...

Your Autofocus Mode Options

One Shot Canon

Choosing the right autofocus mode when using Creative Zone modes, and the way in which focus points are selected is your key to success. Using the wrong mode for a particular type of photography can lead to a series of pictures that are all sharply focused on the wrong subject. When I first started shooting sports with an autofocus SLR (back in the film camera days), I covered one game alternating between shots of base runners and outfielders with pictures of a promising young pitcher, all from...

Using Live View with tethered shooting

Remote Live View Window Canon

One of the most useful ways to use Live View shooting is for shooting still-life subjects such as products, food, stock, and so on with the camera connected to a computer. You can set up with the XSi 450D connected to a computer using the USB cable supplied with the camera. Before you begin, ensure that you have installed the EOS Digital Solution Disk on the computer to which you are connecting the camera. To shoot in Live View with the XSi 450D tethered to the computer, follow these steps 1....

External Flash Function Setting

Canon Harici Fla Ayarlar

This menu is available only when you have a compatible dedicated Canon Speedlite electronic flash attached and switched on. The settings available with the 580 EX II and 430 EX are shown in Figure 7.12. If you press the DISP button while adjusting flash settings, both the changes made to the settings of an attached external flash and to the built-in flash will be cleared. Flash mode. This entry allows you to set the flash mode for the external flash, from E-TTL II, A-TTL, or TTL. All three...

Setting Your Focus To A Single Point

Canon Manual Point 550d

Press the Focus Point Selection button at the top right on the back of the camera and then look in your viewfinder. 2. Rotate the Main dial, and watch the illuminated points change on the rear LCD or in the viewfinder as you move the dial. Select any single point from among the nine available points. If all of the points are lit up, that means you are in automatic focus point selection mode. Keep going until you have just the one point you want selected. Now, to shoot using this focus point,...

Set The Correct White Balance

White balance correction is the process of rendering accurate colors in your final image. Most people don't even notice that light has different color characteristics because the human eye automatically adjusts to different color temperatures, so quickly, in fact, that everything looks correct in a matter of milliseconds. When color film ruled the world, photographers would select which film to use depending on what their light source was going to be. The most common film was balanced for...

Adjusting Color Saturation

Saturation refers to the intensity and purity of color. A fully saturated color contains no black, white, or gray. In other words, saturated colors are deep, rich, and bold. I find that the colors produced by the Rebel XTi 400D are already pretty highly saturated, but on occasion, an image can benefit from a little saturation bump in the digital darkroom. Figure 10-9 offers an example. I was drawn to this scene by the mix of colors, and the original photo, shown on the left in the figure,...

Autofocusing in Live View Mode

Chapter 4 covers the basics of shooting in Live View mode, which enables you to compose your shots by using the camera monitor instead of the viewfinder. As I mention in that discussion, using this photography mode on a digital SLR isn't as simple as it is on a compact point-and-shoot model because of the complexities of SLR design. On the Rebel XS 1000D, shooting in Live View mode requires some tradeoffs, such as not being able to use certain exposure features or any of the fully automatic...

Selecting an autofocus point

Where The Button Rebel

When you shoot in any of the fully automatic exposure modes Full Auto, Portrait, Landscape, and so on as well as in A-DEP mode, all seven of your camera's autofocus points are active. That means that the camera's autofocus-ing system looks at all the points when trying to establish focus. Typically, the camera sets focus on the point that falls over the object closest to the lens. If that focusing decision doesn't suit your needs, you have two options Set the camera to P, Tv, Av, or M exposure...

Adjusting flash power with flash exposure compensation

Camera Symbol Exposure Flash

When you shoot with your built-in flash, the camera attempts to adjust the flash output as needed to produce a good exposure in the current lighting conditions. On some occasions, you may find that you want a little more or less light than the camera thinks is appropriate. You can adjust the flash output by using a feature called flash exposure compensation. This feature works similarly to exposure compensation, discussed earlier in this chapter. But flash exposure compensation affects the...

Choosing and Customizing a Picture Style

Mark Portrait Picture Style

While the name Picture Styles may sound like an optional feature on the XSi 450D, it's important because it determines how the camera delivers tonal curves, color rendering, color saturation, and sharpness in the final image. The Rebel XSi 450D applies a Picture Style for every image that you shoot and it is the foundation for how images are rendered. The XSi 450D offers six Picture Styles, which are detailed in Table 3.2, and it uses the Standard Picture Style as the default style for Creative...

Advanced Shooting with Your Canon EOS Digital Rebel XTi

Now that you have a good understanding of exposure under your belt, you'll want to master some of the other techniques that can contribute to great images. In this chapter, I'm going to show you how to work with some additional exposure options, use the automatic and manual focusing controls available with the Canon EOS Digital Rebel XTi, and explain some of the many ways you can fine-tune your images with optimized white balance, sharpening, tonal values, and color. In Chapter 4, you learned...

Canon Rebel T2i Bulb Setting

If you are new to the world of photography, you might be wondering where in the world the bulb shutter function got its name. After all, wouldn't it make more sense to call it the Manual Shutter setting It probably would, but this is one of those terms that harkens back to the origins of photography. Way back when, the shutter was actually opened through the use of a bulb-shaped device that forced air through a tube, which, in turn, pushed a plunger down, activating the camera shutter. When the...

Viewing Images in Playback Mode

To switch your camera to Playback mode and view the images currently on your memory card, take these steps 1. Press the Playback button, labeled in Figure 4-2 and shown in the margin here. The monitor displays the last picture you took along with some shooting data. To find out how to interpret the picture data and specify what data you want to see, see the upcoming section Viewing Picture Data. If you're curious about your options now, though, press the DISP button to cycle through the...

Replacing Your Clock Battery

Dslr Canon Clock Battery

In addition to the large rechargeable lithium ion battery that provides most of the power for your Canon Digital Rebel XTi, a second battery nestles in the same compartment to provide enough power to retain your current settings and preferences, as well as the local date and time. This coin-sized clock battery is a long-lived C2016 3-volt lithium manganese dioxide cell, located in a slide-out carrier near the hinge of the battery door, shown in Figure 9.7. You may never notice this battery at...

Batch Processing with Capture One

Capture One Pro was one of the first RAW converters providing advanced batch processing, thus improving workflow with RAW files. We prefer to use Capture One in film-strip-mode while batch processing. Principal settings for batch processing with Capture One are made in File rPreferences rProcess Settings see figure 8-8 at page 8-14 . It allows including a copyright note into the output files without calling up of the ITPC metadata dialog. The main section for actual processing are found under...

Setting Up Your Canon EOS Rebel TD

Canon has made the migration path through its Rebel (formerly Digital Rebel) digital camera line so seductively easy that it's a safe bet that many of you are jumping to this latest entry-level model directly from an earlier EOS camera, like the Rebel XSi, or even the relatively new T1i. The enhanced features of the Canon EOS Rebel T2i 550D are hard to resist, including a whopping 18 megapixels of resolution and honest HDTV movie-making capabilities. So, if you do have experience with a...

Adjusting White Balance

I showed you how to adjust white balance in Chapter 3, using the T2i's built-in presets, white balance shift capabilities, and white balance bracketing there's more on bracketing in Chapter 4, too . In most cases, however, the Rebel T2i will do a good job of calculating white balance for you, so Auto can be used as your choice most of the time. Use the preset values or set a custom white balance that matches the current shooting conditions when you need to. The only really problematic light...

Using Flash Control Options

With the XSi 450D, many of the onboard and accessory flash settings are available on the camera menus. The Set-up 2 yellow menu offers onboard flash settings including the first or second curtain shutter sync, Flash Exposure Compensation, and E-TTL II or Average exposure metering. When an accessory Speedlite is mounted, you can use the Set-up 2 yellow menu to set FEC and to set Evaluative or Average flash metering. In addition, you can change or clear the Custom Function C.Fn settings for...

Setting Up For A Waterfall Shot

Attach the camera to your tripod, then compose and focus your shot. 2. For the best quality, make sure the ISO is set to 100. 3. Using Av mode, set your aperture to the smallest opening such as f 22 or f 36 . 4. Press the shutter button halfway so the camera takes a meter reading. 5. Check to see if the shutter speed is 1 15 or slower. 6. Take a photo and then check the image on the LCD. If the water is blinking on the LCD, indicating a loss of detail in the highlights, then use the Exposure...

Canon Picture Styles

Canon 550d Sharpness

Picture Styles are extremely flexible. Canon has set the parameters for the five predefined color Picture Styles and the single monochrome Picture Style to suit the needs of most photographers. But you can adjust any of those canned Picture Styles to settings you prefer. Better yet, you can use those three User Definition files to create brand new styles that are all your own. If you want rich, bright colors to emulate Velvia film or the work of legendary photographer Pete Turner, you can build...

Working with Memory Cards

Canon T90 Memory Card

Instead of recording images on film, digital cameras store pictures on memory cards. Some people, in fact, refer to memory cards as digital film, but I hate that term because film and memory cards actually have little in common. Film must be developed before you can view your pictures, a process that involves time and some not-so-nice chemicals. Film can be damaged when exposed to some airport security scanners memory cards are immune to those devices. The cost per picture is also much higher...

Replacing the Date Time Battery

The date time back-up battery maintains the camera's date and time. Its service life is about 5 years. If the date time is reset when the battery is replaced, replace the back-up battery with a new CR2016 lithium battery as described below. The date time setting will also be reset, so be sure to set the correct date time. 1 Set the power switch to lt OFF gt . Make sure the battery is in the proper - orientation. Then load the battery and close the cover. For the date time battery, be sure to...

Direct Direct Transfer IndirectDirect Transfer

There are some advantages to transferring photos directly from your EOS 40D to a computer. The destination computer doesn't need to have a card reader all it requires is a USB port. So, if you have the USB cable that came with your camera, you can transfer photos to any computer that has the Canon utility software discussed later installed. However, direct transfer uses your 40D's internal battery power, while removing the card and transferring the photos with a card reader installed on the...

Choosing White Balance Options

If you would rather spend your time shooting instead of sitting at the computer color-correcting images, then learning about and using the 40D's White Balance options are very important. Different shooting scenes, the type and consistency of light, the ICC is an abbreviation for International Color Consortium, which promotes the use and adoption of open, vendor-neutral, cross-platform color management systems. This group introduced the standard device profile format used to characterize color...

Using an External Flash

On the top of the camera sits a hotshoe, a fairly standard camera interface that allows you to use a number of different accessories. It's called a hotshoe because it's an interface that provides electrical contacts through which the camera can communicate with an attached accessory as opposed to a coldshoe, which has the same type of mount but provides no communication between the camera body and whatever is in the shoe . You can attach an external flash to the hotshoe on the top of the...

Decoding Viewfinder Data

When the camera is turned on, you can view critical exposure settings and a few other pieces of information in the viewfinder as well as on the Camera Settings display. The viewfinder data changes depending on what action you're currently undertaking. For example, when you press the shutter button halfway, you see the current f-stop aperture setting , shutter speed, and exposure meter, as shown in Figure 1-13. Figure 1-13 You also can view some camera information at the bottom of the...

Setting the ISO Sensitivity

Setting the ISO determines the sensitivity of the image sensor to light. At low settings such as ISO 100, the sensor needs comparatively more light to make an exposure than at a high ISO setting such as 800. However, as the sensitivity setting increases on a digital camera a higher ISO number , the output of the sensor is also amplified. So while you have the option of increasing the ISO sensitivity at any point in shooting, the tradeoff in increased amplification or the accumulation of an...

Understanding color temperature

Few people think of light as having color until the color becomes obvious, such as at sunrise and sunset when the sun's low angle causes light to pass through more of the earth's atmosphere, creating visible and often dramatic color. However, regardless of the time of day, natural light has a color temperature, and each color, or hue, of sunlight renders subjects differently. Likewise, household bulbs, candlelight, flashlights, and electronic flashes all have distinct color temperatures. As...

Getting the Right Exposure

Zone Canon Evaluative Metering Image

The Canon EOS Digital Rebel XTi gives you complete control over many of the basic functions of the camera. These include exposure, sensitivity ISO settings , color balance, focus, and image parameters like sharpness and contrast. You can choose to let the camera set any or all of these for you automatically. Or, you can opt to fine-tune how the XTi applies its automatic settings. If you want absolute creative control over any of these functions, you can set them manually, too. That's why the...

Manipulating Depth of Field

Stop Examples

Getting familiar with the concept of depth of field is one of the biggest steps you can take to becoming a more artful photographer. I introduce you to depth of field in Chapters 2 and 5, but here's a quick recap just to hammer home the lesson II Depth of field refers to the distance over which objects in a photograph appear sharply focused. With a shallow, or small, depth of field, only your subject and objects very close to it appear sharp. Objects at a distance from the subject appear...

Installing and Removing the CF Card

The captured image is recorded onto the CF card optional . Although the thickness is different between the Type I and Type II CF cards, either one can be inserted into the camera. The camera is also compatible with Microdrive hard disk-type and CF cards with 2 GB or higher capacity. Slide the cover as shown by the arrow to open it. As shown in the illustration, face the label side toward you and insert the end with the small holes into the camera. Inserting the CF card in the wrong way may...

Using tethered or wireless connection

One of the most useful ways to use Live View shooting is for studio work, particularly when you're shooting still-life subjects such as products, food, stock shots, and so on. You can set up with the 40D connected to a computer using the USB cable supplied with the camera. The extra-long cord allows a decent range of movement, particularly if the computer is on a wheeled or swivel table. You can also shoot with the optional wireless file transmitter, such as the Wireless File Transmitter WFT-E3...

Using a Card Reader and Software

You can also use a Compact Flash memory card reader and software to transfer photos and automate the process using the EOS Utility, Photoshop Elements' Photo Downloader, or the downloading program supplied with some other third-party applications. This method is more frugal in its use of your 40D's battery and can be faster if you have a speedy USB 2.0 or FireWire card reader attached to an appropriate port. The installed software automatically remains in memory as you work, and it recognizes...

Using The Right Format Raw Vs Jpeg

When shooting with your T2i, you have a choice of image formats that your camera will use to store the pictures on the memory card. JPEG is probably the most familiar format to anyone who has been using a digital camera. I touched on this topic briefly in Chapter 1, so you already have a little background on what JPEG and RAW files are. There is nothing wrong with JPEG if you are taking casual shots. JPEG files are ready to use, right out of the camera. Why go through the process of adjusting...

Choosing a Color Space sRGB vs Adobe RGB

Canon Srgb Adobe Rgb

Normally, your camera captures images using the sRGB color mode, which simply refers to an industry-standard spectrum of colors. The s is for standard, and the RGB is for red-green-blue, which are the primary colors in the digital imaging color world. This color mode was created to help ensure color consistency as an image moves from camera or scanner to monitor and printer the idea was to create a spectrum of colors that all of these devices can reproduce. However, the sRGB color spectrum...

Recovering Deleted Images

There will probably come a day when you will accidentally delete an image, or even accidentally format your camera's media card. You might be able to recover deleted images from your camera's media card. The reason it's possible to recover files that have been erased is that when you delete a file, the camera doesn't actually erase the image data. Instead, it removes that image's entry from the directory of contents on the card and marks that image's space as available. Even if you have already...

How To Set Aperture On Canon 450d

Aperture-priority AE mode is shown on the camera Mode dial as Av. Av mode is a semiautomatic mode that enables you to control the aperture. In this mode, you change the aperture by turning the Main dial, and then the camera automatically calculates and sets the appropriate shutter speed. As detailed earlier, aperture is the primary factor that controls the depth of field. A wide aperture, such as f 3.5, provides a shallow depth of field that softly blurs the background. A narrow aperture, such...

Using the Builtin Flash

E-TTL II autoflash obtains high-precision and consistent flash shots. Using the Built-in Flash in the Basic Zone If necessary, the built-in flash will pop-up automatically in low-light or backlit conditions, (except in < 3ik> < E3> modes) Using the Built-in Flash in the Creative Zone Regardless of the light level, you can press the button to pop-up and fire the built-in flash whenever desired. P For fully automatic flash photography. The shutter speed (1 60 sec. - 1 250 sec.) and...

Auto Exposure Bracketing

Auto Exposure Bracketing AEB is a way to ensure that at least one exposure in a series of three images is acceptable. With AEB turned on, you can take three pictures at three different exposures one picture at the standard exposure set by the camera, one picture at an increased lighter exposure, and another picture at a decreased darker exposure. The camera is initially set to 1 3 f-stop increment exposure changes. If you want a greater level of exposure difference, you can set C.Fn-1 to Option...

How Connect Canon 350d

Your Rebel XTi 400D is equipped with a video-out port, which is tucked under the little rubber cover on the left rear side of the camera, as shown in Figure 9-16. That feature means that you can output your pictures for display on a television screen. To take advantage of this option, dig through your camera box until you find the video cable, which has little yellow plug ends like the one you see on the right in Figure 9-16. Then, making sure that the camera is off, use the cable to connect...

After turning on or waking the camera, select one of the shooting modes in the Creative zone such as P (you can't select the white balance when using any of the Basic modes). 2. Press the WB button on the back of the camera to bring up the white balance menu. It is the top button on the Cross keys. 3. Use the left right Cross keys to select the proper white balance for your shooting situation. 4. Press the Set button to lock in your selection. 5. Check the camera display to ensure that the...

M Manually Setting the Shutter Speed and Aperture

You can manually set the shutter speed and aperture to shoot When you press the shutter button halfway, the difference between the standard exposure* and the selected exposure appears on the LCD monitor. If the difference is more than 2 stops, -2 or +2 appears in red. * Standard exposure levels are calculated by measuring light according to the currently selected metering mode. If you wish to change the exposure, select shuttc speed or aperture using the button, then adjust the value using the...

Updating the XSiD Firmware

One of the greatest advantages of owning a digital camera such as the XSi 450D is that Canon often posts updates to the firmware (the internal instructions) for the camera to its Web site. New firmware releases can add improved functionality to existing features and, in some cases, fix reported problems with the camera. New firmware along with ever-improving software keeps your camera and your ability to process images current as technology improves. To determine if you need to update firmware,...

Using Only The Center Focus Point

Center Point Focus

Some people like to set the focus point on the center point to gain better control of the camera's autofocus mechanism. The technique works like this set the T1i to the center focus point, and from now on you'll know that the camera will always focus on the center. If you have a tricky composition, you can place the center focus point on your subject, press the shutter button down halfway to lock focus, and then reframe while continuing to hold down the shutter button. To guarantee that the...

Changing the AF autofocus mode

Your camera offers three different autofocusing schemes, which you select through a control called AF mode. The three choices work like so 1 One-Shot In this mode, which is geared to shooting stationary subjects, the camera locks focus when you depress the shutter button halfway. Focus remains locked as long as you hold the shutter button at that halfway position. 1 AI Servo In this mode, the camera adjusts focus continually as needed from the time you press the shutter button halfway to the...

Exposure Compensation value

This option, also detailed in Chapter 5, enables you to produce a brighter or darker image than the camera's autoexposure meter thinks appropriate. If you applied exposure compensation when you take a picture, the compensation amount appears to the right of the f-stop during playback. Otherwise, this area of the display is empty.

Adep And Hyperfocal Distance

Canon 550d Display Raw Jpeg Quality Mode

A-DEP is a simplified version of a related mode found in some higher-end Canon digital and film models called DEP. DEP allows you to manually select the nearest and farthest points you want in focus, and the camera will then adjust the focus point to a setting known as the hypefocal distance. At the hyperfocal distance, everything from half that distance to infinity will be in acceptable focus. Although many photographers elect to set hyperfocal distance themselves, the exact distance varies by...

Restoring the Cameras Default Settings

With all the different settings, you may sometimes want to start fresh instead of backtracking to reset individual settings. The 5D Mark II offers several restore settings, including a Clear all camera settings option as well as a Clear copyright info option that allows you to clear the information that you entered in EOS Utility. This option is a good way to start fresh, but be aware that it resets all shooting and image-quality settings back to the factory defaults. In addition to the...

Using an external flash unit

Canon Built Flash Concentrate

In addition to its built-in flash, your camera has a hot shoe, which is photo-geek terminology for a connection that enables you to add an external flash head like the one shown in Figure 5-29. The figure features the Canon Speedlite 580EX II, which currently retails for right around 350. Although certainly not the cheapest of camera accessories, an external flash may be a worthwhile investment if you do a lot of flash photography, especially portraits. For one thing, an external flash offers...

Trigger circuit voltage

Old flash units - both studio and hotshoe-mount - used pretty high voltages between the camera and the flash - often from 25 to 250 volts. This is because the flash units were fired by simple switches - electrical contacts. Modern cameras, however, rely on electronic circuitry rather than electric switches. This allows for more flexibility and the possibility for computerization, but the circuits can't withstand high trigger circuit voltages anything above 6 volts, in the case of EOS cameras,...

Flash Exposure Compensation

Flash Exposure Compensation is much like Auto Exposure Compensation in that you can set compensation for exposure up to plus minus two stops in 1 3-stop increments. A positive compensation increases the flash output and a negative compensation decreases the flash output. Flash Exposure Compensation can help reduce shadows in the background and balance unevenly lit scenes.

Most of Canon's high-end flash units have sockets on the side which can accommodate external high-voltage 270 volts battery packs. These packs have two basic functions - they speed up the flash's recycle time between shots to a second or two critical for news or wedding photography and extend the time you can go between changing batteries. They're also useful in cold weather battery performance always drops precipitately at freezing temperatures since you can stuff the pack inside your jacket...

Customizing White Balance

Back in the film days, color films were standardized, or balanced, for a particular color of light. Digital cameras like the EOS 40D use a particular white balance matched to the color of light used to expose your photograph. The right white balance is measured using a scale called color temperature. Color temperatures were assigned by heating a mythical black body radiator and recording the spectrum of light it emitted at a given temperature in degrees Kelvin. So, daylight at noon has a color...

Front and Rear Curtain Sync

All Canon EOS cameras have two moving curtains in the shutter mechanism. The front curtain opens the shutter, and the rear curtain closes it. The normal operation of the shutter and flash causes the flash to fire immediately when the front curtain opens. This is Front Curtain Sync, and it's fine for most general flash applications. But say your subject is moving and you're panning the camera by using a slow shutter speed to pick up some ambient light. Flash photography in this mode produces...

Avoiding Sync Speed Problems

Using a shutter speed faster than 1 200th second can cause problems. Triggering the electronic flash only when the shutter is completely open makes a lot of sense if you think about what's going on. To obtain shutter speeds faster than 1 200th second, the T2i exposes only part of the sensor at one time, by starting the second curtain on its journey before the first curtain has completely opened, as shown in Figure 7.9. That effectively provides a briefer exposure as the open slit between the...

Setting a custom white balance

Setting a custom white balance is an option that produces very accurate color because the white balance is set precisely for the light in the scene. To use this option, you photograph a white or gray card, select the image in the camera, and then the camera imports the color data and uses it to set the color temperature for images. This approach is effective when you're shooting a series of shots in scenes where the light doesn't change. 3.8 This image was taken using the Flash White Balance...

Creating a custom white balance setting

If none of the preset white balance options produces the right amount of color correction, you can create your own custom setting. To use this technique, you need a piece of card stock that's either neutral gray or absolute white not eggshell white, sand white, or any other close-but-not perfect white. You can buy reference cards made just for this purpose in many camera stores for under 20. Position the reference card so that it receives the same lighting you'll use for your photo. Then take...

Choosing a RAW Conversion Program

RAW image data is stored in proprietary format, which means that the RAW images can be viewed and converted using the camera manufacturer's RAW conversion program, such as Canon's Digital Professional Pro conversion program, or a third-party RAW conversion program such as Adobe's Camera Raw plug-in or Adobe Lightroom, or Aperture. Unlike TIFF and JPEG files, RAW files cannot be moved from computer to computer with the assurance that any operating system can display them. That means you must...

Time LapseInterval Photography

Who hasn't marveled at a time-lapse photograph of a flower opening, a series of shots of the moon marching across the sky, or one of those extreme time-lapse picture sets showing something that takes a very, very long time, such as a building under construction. You probably won't be shooting such construction shots, unless you have a spare 40D you don't need for a few months (or are willing to go through the rigmarole of figuring out how to set up your camera in precisely the same position...

White Balance Library

Shoot a selection of blank-card images under a variety of lighting conditions on a spare memory card. If you want to recycle one of the color temperatures you've stored, insert the card and set the custom white balance to that of one of the images in your white balance library, as described above. White balance shift allows you to dial in a white balance color bias along the blue amber yellow dimensions, and or magenta green scale. In other words, you can set your color balance so that it is a...

White Balance Shift Bracket

Similar to Auto Exposure Bracketing, White Balance Shift Bracket can produce from one to three color variations from a single exposure. It's an interesting feature because you don't need to shoot a bracket set, which means that if you routinely like your images a little warmer or cooler, or a little more yellow or green, you can set the screen where you wish. From the moment the feature is engaged, all of your images will exhibit the color change, regardless of which white balance mode you are...

Setting a white balance shift

Similar to white balance autobracketing, you can manually set the color bias of images to a single setting by using white balance shift. The color can be biased toward blue B , amber A , magenta M , or green G in up to nine levels measured as mireds, or densities. Each level of color-correction you set is equivalent to 5 mireds of a color-temperature conversion filter. When you set a color shift or bias, it's used for all images until you change the setting. On the 5D Mark II, color...

Adjusting the Viewfinder Focus

Perched on the top right edge of the viewfinder is a tiny black knob, officially called the dioptric adjustment control. I labeled the knob in Figure 1-4. With this control, you can adjust the magnification of the viewfinder to mesh with your eyesight. If you don't take this step, scenes that appear out-of-focus through the viewfinder may actually be sharply focused through the lens, and vice versa. Here's how to make the necessary adjustment 1. Remove the lens cap from the front of the lens....

Fixing Exposures with Histograms

While you can often recover poorly exposed photos in your image editor, your best bet is to arrive at the correct exposure in the camera, minimizing the tweaks that you have to make in post-processing. However, you can't always judge exposure just by viewing the image on your 40D's LCD after the shot is made. Nor can you get a 100 percent accurately exposed picture by using the 40D's Live View exposure simulation feature described in Chapter 3. Ambient light may make the LCD difficult to see,...

Mixed-light scenes, such as tungsten and daylight, can wreak havoc on getting accurate or visually pleasing image color. Two options work well to get neutral color quickly in mixed lighting scenes. If you're shooting RAW capture, one option is to shoot a gray or white card as described in the earlier sidebar. The second option is to set a custom white balance. Setting a custom white balance balances colors for the specific light or combination of light types in the scene. A custom white balance...

Wide-angle lenses have a few quirks that you'll want to keep in mind when shooting so you can avoid falling into some common traps. Here's a checklist of tips for avoiding common problems Symptom converging lines. Unless you want to use wildly diverging lines as a creative effect, it's a good idea to keep horizontal and vertical lines in landscapes, architecture, and other subjects carefully aligned with the sides, top, and bottom of the frame. That will help you avoid undesired perspective...

Custom Function specifics

In this section, I explain each of the Custom Functions and the options that you can set. As you read about each Custom Function, consider how you could use it to simplify or customize the camera. You don't have to set each option, and it is likely you may find only a few that are useful to you in the beginning. But as you continue shooting, you'll likely grow to appreciate the power that they offer. Keep in mind that the functions are easy to find, so you can go back and reset them if you...

Choosing the file format and quality

The file format and quality level that you use to take your pictures are two of the most important decisions that you make.

Table 1.1 explains the options that you can choose from. With the high-quality images that the XSi 450D delivers, you can make beautiful enlargements from these images. Even if you don't...

Architectural and Interior Photography

Styles of architecture mirror the culture and sensibilities of each generation. New architecture reflects the hopeful aspirations of the times, while older structures reflect earlier cultural norms and sensibilities. For photographers, photographing both new and old architecture provides rich photo opportunities to document changes in culture and urban development. The versatility of the Rebel XSi 450D and the color-rich 14-bit files make the XSi 450D a very capable camera for architectural and...

Extension tubes and closeup lenses

Canon Eos Rebel Xsi 450d Accessories

Extension tubes are close-up accessories that provide magnification from approximately 0.3 to 0.7 and can be used on many EF lenses, though there are exceptions. Extension tubes are placed between the camera body and lens and connect to the camera via eight electronic contact points. The function of the camera and lens is unchanged, and you can combine extension tubes for greater magnification. Canon offers two extension tubes, the EF 12 II and the EF 25 II. Magnification differs by lens, but...

Understanding the Focal Length Multiplication Factor

The Rebel XSi 450D image sensor is 1.6 times smaller than a traditional 35mm film frame. It is important to know the sensor size because it not only determines the size of the image but also affects the angle of view of the lenses you use. A lens's angle of view is how much of the scene, side to side and top to bottom, that the lens includes in the image. For example, a 15mm Fisheye lens has a 180-degree angle of view. By contrast, a 200mm lens has a scant 12-degree angle of view. Further, the...

Turn Off The Release Shutter Without Card Setting

If you really want to ruin your day, try shooting for a couple of hours only to find that you didn't put a memory card in your camera and thus didn't save any of the pictures that you've taken. This was always a concern with film shooters, and it hasn't gone away with digital SLRs. You see, camera manufacturers want to give prospective buyers a way to test out the camera without having to keep a memory card in it, so they came up with a setting called Release Shutter without Card. When your...

Downloading with a USB Cable

Checking depth of field

When you look through your viewfinder and press the shutter button halfway, you can get only a partial indication of the depth of field that your current camera settings will produce. You can see the effect of focal length and the camera-to-subject distance, but because the aperture doesn't actually open to your selected f-stop until you take the picture, the viewfinder doesn't show you how that setting will affect depth of field. By using the Depth-of-Field Preview button on your camera,...
