Image Stabilization

Canon has a burgeoning line of more than a dozen lenses with built-in image stabilization (IS) capabilities. This feature uses lens elements that are shifted internally in response to the motion of the lens during handheld photography, countering the shakiness the camera and photographer produce and which tele-photo lenses magnify. However, IS is not limited to long lenses the feature works like a champ at the 17mm zoom position of Canon's EF-S 17-85MM f4-5.6 IS USM and EF-S 17-55 f 2.8 IS USM...

All New Features

The Canon EOS 40D, like its predecessors, is a mid-level digital SLR, intended as a step up from entry-level cameras like the Digital Rebels. It's suitable for more advanced photographers, especially those who can live without the most advanced features found in Canon's pro line, such as the Canon EOS-1D Mark III or Canon EOS-1Ds Mark III. Even so, the 40D is upscale enough to excite any avid photographer. For example, its magnesium alloy body and weatherproofing of the battery compartment and...

Lens Hoods

Lens hoods are an important accessory for all lenses, but they're especially valuable with telephotos. As I mentioned earlier, lens hoods do a good job of preserving image contrast by keeping bright light sources outside the field of view from striking the lens and, potentially, bouncing around inside that long tube to generate flare that, when coupled with atmospheric haze, can rob your image of detail and snap. In addition, lens hoods serve as valuable protection for that large, vulnerable,...

Working with Lenses

If Canon has one advantage over many of the other vendors of digital SLRs (other than making great, affordable cameras), it's the mind-bending assortment of high quality lenses available to enhance the capabilities of cameras like the Canon EOS 40D. Thousands of current and older lenses introduced by Canon and third-party vendors since 1987 can be used to give you a wider view, bring distant subjects closer, let you focus closer, shoot under lower light conditions, or provide a more detailed,...

Speedlite EX II

This flagship of the Canon accessory flash line is the most powerful unit the company offers, with a GN of190, and a manual automatic zoom flash head that covers the full frame of lenses from 24mm wide angle to 105mm telephoto. (There's a flip-down wide-angle diffuser that spreads the flash to cover a 14mm lens's field of view, too.) All angle specifications given by Canon refer to full-frame sensors, but this flash unit automatically converts its field of view coverage to accommodate the crop...

Focus Pocus

Although Canon added autofocus capabilities in the 1980s, back in the day of film cameras, prior to that focusing was always done manually. Honest. Even though viewfinders were bigger and brighter than they are today, special focusing screens, magnifiers, and other gadgets were often used to help the photographer achieve correct focus. Imagine what it must have been like to focus manually under demanding, fast-moving conditions such as sports photography. Focusing was problematic because our...

Choosing a Metering Method

The 40D has four different schemes for evaluating the light received by its exposure sensors. You can choose among them by pressing the Metering Mode Selection button on the top panel, and using the Main Dial until the icon for the mode you want appears in the status LCD. Evaluative. The 40D slices up the frame into 35 different zones, shown in Figure 4.3 (the status LCD icon is shown in the upper-left corner). The zones used are linked to the autofocus system. The camera evaluates the...

What Can Go Wrong

There are lots of things that can go wrong with your memory card, but the ones that aren't caused by human stupidity are statistically very rare. Yes, a Compact Flash card's internal bit bin or controller can suddenly fail due to a manufacturing error or some inexplicable event caused by old age. However, if your CF card works for the first week or two that you own it, it should work forever. There's really not a lot that can wear out. The typical Compact Flash card is rated for a Mean Time...

Incandescent Tungsten Light

The term incandescent or tungsten illumination is usually applied to the direct descendents of Thomas Edison's original electric lamp. Such lights consist of a glass bulb that contains a vacuum, or is filled with a halogen gas, and contains a tungsten filament that is heated by an electrical current, producing photons and heat. Tungsten-halogen lamps are a variation on the basic light bulb, using a more rugged (and longer-lasting) filament that can be heated to a higher temperature, housed in a...

Bracketing

Bracketing is a method for shooting several consecutive exposures using different settings, as a way of improving the odds that one will be exactly right. Before digital cameras took over the universe, it was common to bracket exposures, shooting, say, a series of three photos at 1 125th second, but varying the f stop from f 8 to f 11 to f 16. In practice, smaller than whole-stop increments were used for greater precision. Plus, it was just as common to keep the same aperture and vary the...

What Lenses Can Do for

A saner approach to expanding your lens collection is to consider what each of your options can do for you and then choosing the type of lens that will really boost your creative opportunities. Here's a general guide to the sort of capabilities you can gain by adding a lens to your repertoire. Wider perspective. Your 18-55mm f 3.5-5.6 or 17-85mm f 4-5.6 lens has served you well for moderate wide-angle shots. Now you find your back is up against a wall and you can't take a step backwards to take...

Setting Image Parameters

You can fine-tune the images that you take in several different ways. For example, if you don't want to choose a predefined white balance or use white balance bracketing (both discussed earlier in this book), you can set a custom white balance based on the illumination of the site where you'll be taking photos, or choose a white balance based on color temperature. With the Picture Styles options, you can set up customized sharpening, tone, color, saturation, and hue for various types of...

Expert Shield For Canon Eos 40d

Shooting Your First Canon EOS 40D Picture If I were a betting person, I'd be willing to wager that you've already taken at least a few hundred shots with your new Canon EOS 40D. As valuable as a book like this one is, nobody can suppress their excitement long enough to read the instructions before initiating play with a new toy. My first photo with this camera was a snapshot of the owner of the photo store where I bought my 40D. As a long-time Canon owner, I purchased just the 40D body (sans...

Tiny Slice of Time

Exposures that seem impossibly brief can reveal a world we didn't know existed. In the 1930s, Dr. Harold Edgerton, a professor of electrical engineering at MIT, pioneered high-speed photography using a repeating electronic flash unit he patented called the stroboscope. As the inventor of the electronic flash, he popularized its use to freeze objects in motion, and you've probably seen his photographs of bullets piercing balloons and drops of milk forming a coronet-shaped splash. Electronic...

Program Mode

Program mode (P) uses the 40D's built-in smarts to select the correct f stop and shutter speed using a database of picture information that tells it which combination of shutter speed and aperture will work best for a particular photo. If the correct exposure cannot be achieved at the current ISO setting, the shutter speed indicator in the viewfinder will blink 30 or 8,000, indicating under- or overexposure (respectively). You can then boost or reduce the ISO to increase or decrease...

Three Ways to Take Long Exposures

There are actually three common types of lengthy exposures timed exposures, bulb exposures, and time exposures. The EOS 40D offers only the first two, but once you understand all three, you'll see why Canon made the choices it did. Because of the length of the exposure, all of the following techniques should be used with a tripod to hold the camera steady. Timed exposures. These are long exposures from 1 second to 30 seconds, measured by the camera itself. To take a picture in this range,...

Exposure

The Canon EOS 40D 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 40D 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 40D is such a...

Choosing a Creative Zone Exposure Method

You'll find five methods for choosing the appropriate shutter speed and aperture within the Creative Zone settings. Just spin the Mode Dial to choose the method you want to use. Your choice of which is best for a given shooting situation will depend on things like your need for lots of (or less) depth-of-field, a desire to freeze action or allow motion blur, or how much noise you find acceptable in an image. Each of the EOS 40D's exposure methods emphasizes one aspect of image capture or...

Dust the FAQs Maam

Here are some of the most frequently asked questions about sensor dust issues. Q. I see tiny specks in my viewfinder. Do I have dust on my sensor A. If you see sharp, well-defined specks, they are clinging to the underside of your focus screen and not on your sensor. They have absolutely no effect on your photographs, and are merely annoying or distracting. Q. I can see dust on my mirror. How can I remove it A. Like focus-screen dust, any artifacts that have settled on your mirror won't affect...

Dealing with Noise

Image noise is that random grainy effect that some like to use as a visual effect, but which, most of the time, is objectionable because it robs your image of detail even as it adds that interesting texture. Noise is caused by two different phenomena high ISO settings and long exposures. High ISO noise commonly appears when you raise your camera's sensitivity setting above ISO 400. With Canon cameras, which are renown for their good ISO noise characteristics, noise may become visible at ISO...

Basic Zone Flash

When the 40D is set to one of the Basic Zone modes (except for Landscape, Sports, or Flash Off modes), the built-in flash will pop up when needed to provide extra illumination in low-light situations, or when your subject matter is back-lit and could benefit from some fill flash. The flash doesn't pop up in Landscape mode because the flash doesn't have enough reach to have much effect for pictures of distant vistas in any case nor does the flash pop up automatically in Sports mode, because...

Using Autofocus with Live View

You can temporarily interrupt Live View mode to allow the EOS 40D to use autofocus. Because the step takes a few seconds, you're better off using autofocus when the camera is mounted on a tripod. If you handhold the 40D, you may displace the point of focus achieved by the autofocus system. Canon also recommends that you use One Shot focus and center the focus point. You can use Al-Servo and automatic or manual focus point selection, but if the focus point doesn't coincide with the subject you...

Focus Modes

The 40D has three AF modes One Shot AF (also known as Single Autofocus), AI Servo (Continuous Autofocus), and AI Focus AF (which switches between the two as appropriate). I'll explain all of these in more detail later in this section. With manual focus activated by sliding the switch on the lens, your 40D lets you set the focus yourself. There are some advantages and disadvantages to this approach. While your batteries will last longer in manual focus mode, it will take you longer to focus the...

Photoshop CS

The latest version of Photoshop includes a built-in RAW plug-in that is compatible with the proprietary formats of a growing number of digital cameras, both new and old. This plug-in also works with Photoshop Elements 6.0. To open a RAW image in Photoshop CS3, just follow these steps (Elements 5.0 and 6.0 users can use much the same workflow, although fewer settings are available) 1. Transfer the RAW images from your camera to your computer's hard drive. 2. In Photoshop, choose Open from the...

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...

Getting into Focus

Learning to use the Canon EOS 40D's autofocus system is easy, but you do need to fully understand how the system works to get the most benefit from it. Once you're comfortable with autofocus, you'll know when it's appropriate to use the manual focus option, too. The important thing to remember is that focus isn't absolute. For example, some things that look in sharp focus at a given viewing size and distance might not be in focus at a larger size and or closer distance. In addition, the goal of...

Avoiding Telephoto Lens Problems

Many of the problems that telephoto lenses pose are really just challenges and not that difficult to overcome. Here is a list of the seven most common picture maladies and suggested solutions. Symptom flat faces in portraits. Head-and-shoulders portraits of humans tend to be more flattering when a focal length of 50mm to 85 mm is used. Longer focal lengths compress the distance between features like noses and ears, making the face look wider and flat. A wide-angle might make noses look huge and...

How Electronic Flash Works

The bursts of light we call electronic flash are produced by a flash of photons generated by an electrical charge that is accumulated in a component called a capacitor and then directed through a glass tube containing xenon gas, which absorbs the energy and emits the brief flash. For the pop-up flash built into the EOS 40D, the full burst of light lasts about 1 1,000th of a second and provides enough illumination to shoot a subject 10 feet away at f 4 using the ISO 100 setting. In a more...

Enabling Live View

You need to take some steps before using Live View. This workflow prevents you from accidentally using Live View when you don't mean to, thus potentially losing a shot, and it also helps ensure that you've made all the settings necessary to successfully use the feature efficiently. Here are the steps to follow 1. Set focus to Manual. It's a good idea to set the lens focus switch to the MF position, because most Live View pictures are taken using manual focus. Take this step now so you won't...

Advanced Shooting with Your Canon EOS D

Getting the right exposure is one of the foundations of a great photograph, but a lot more goes into a compelling shot than good tonal values. A sharp image, proper white balance, good color, and other factors all can help elevate your image from good to exceptional. So, now that you've got a good understanding of exposure tucked away, you'll want to learn how to work with some additional exposure options, use the automatic and manual focusing controls available with the Canon EOS 40D, and...

Selecting an Autofocus Exposure Zone Manually

If you're using P, Av, Tv, or M shooting modes and Evaluative Metering, you can select the autofocus zone manually (and thus the zone linked to the metering system). As I mentioned in Chapter 1, the EOS 40D uses nine different focus points to calculate correct focus. In A-DEP, or any of the Basic Zone shooting modes, the focus point is selected automatically by the camera. In the other Creative Zone modes, you can allow the camera to select the focus point automatically, or you can specify...

Dragging and Dropping

The final way to move photos from your memory card to your computer is the old-fashioned way manually dragging and dropping the files from one window on your computer to another. The procedure works pretty much the same whether you're using a Mac or a PC. 1. Remove the Compact Flash card from the EOS 40D and insert it in your memory card reader. 2. Using Windows Explorer, My Computer, or your Mac desktop, open the icon representing the memory card, which appears on your desktop as just another...

Telephoto Extenders

Telephoto extenders (often called teleconverters outside the Canon world) multiply the actual focal length of your lens, giving you a longer telephoto for much less than the price of a lens with that actual focal length. These extenders fit between the lens and your camera and contain optical elements that magnify the image produced by the lens. Available in 1.4X and 2.0X configurations from Canon, an extender transforms, say, a 200mm lens into a 280mm or 400mm optic, respectively. Given the...

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...

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...

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,...

Upgrading to the Canon EOS D

Are you ready to upgrade to the Canon EOS 40D from an EOS 30D, or, even, an earlier model like the 20D or 10D Perhaps you own a Digital Rebel in one of its incarnations, and lust for some of the muscular new features found in the 40D. You might even be a die-hard film camera owner with an earlier EOS model, and lots of EF lenses that will work great on the new Canon 40D. If you fall into any one of these categories, you probably want to know what's new before you make the jump. This appendix...

Adjusting White Balance

I showed you how to adjust white balance in Chapter 3, using the 40D's built-in presets, white balance shift capabilities, setting exact color temperatures, and white balance bracketing (there's more on bracketing in Chapter 4, too). In most cases, however, the EOS 40D 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...

Working with Light

All artists, including sculptors, painters, and photographers, use light as their medium to create images. Each of these types of creative work has its own challenges. Sculptors, for example, don't have control over the light used to illuminate their work, so they must create shapes using planes and curved surfaces so that the form envisioned by the artist comes to life from a variety of viewing and lighting angles. Painters, in contrast, have absolute control over both shape and light in their...

Image Editors

Image editors are general-purpose photo editing applications that can do color correction, tonal modifications, retouching, combining of several images into one, and usually include tools for working with RAW files and reducing noise. So, you'll find programs like those listed here good for all-around image manipulation. The leading programs are Adobe Photoshop CS3 Photoshop Elements 6.0. Photoshop CS3 is the serious photographer's number one choice for image editing, and Elements is an...

Instead, you can spin the Mode Dial to the appropriate Basic Zone mode and fire...

Aperture Priority

In Av mode, you specify the lens opening used, and the 40D selects the shutter speed. Aperture Priority is especially good when you want to use a particular lens opening to achieve a desired effect. Perhaps you'd like to use the smallest f stop possible to maximize depth-of-field in a close-up picture. Or, you might want to use a large f stop to throw everything except your main subject out of focus, as in Figure 4.8. Maybe you'd just like to lock in a particular f stop because it's the...

Your Autofocus Mode Options

Choosing the right autofocus mode 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 a position next to the third...

Diffusing and Softening the Light

Direct light can be harsh and glaring, especially if you're using the flash built into your camera, or an auxiliary flash mounted in the hot shoe and pointed directly at your subject. The first thing you should do is stop using direct light unless you're looking for a stark, contrasty appearance as a creative effect . There are a number of simple things you can do with both continuous and flash illumination. Use window light. Light coming in a window can be soft and flattering, and a good...

Avoiding Potential Wide Angle Problems

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...

Improved Cross Type Focus Points

One improvement that new Canon EOS 40D owners sometimes overlook is the upgrade to cross-type focus points at all nine focus zone positions with lenses having that f 5.6 or larger maximum aperture , plus a center cross-type focus point that is extra sensitive when used with lenses having a maximum f stop of f 2.8 or better. Why is this important It helps to review exactly how the 40D determines focus. The camera looks for contrast between adjacent pixels to determine relative sharp-ness...

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...

Shutter Priority

Here are some things to try Make people invisible. One very cool thing about long exposures is that objects that...

Continuous Shooting

The Canon EOS 40D's pair of Continuous Shooting modes remind me how far digital photography has brought us. The first accessory I purchased when I worked as a sports photographer some years ago was a motor drive for my film SLR. It enabled me to snap off a series of shots in rapid succession, which came in very handy when a fullback broke through the line and headed for the end zone. Even a seasoned action photographer can miss the decisive instant when a crucial block is made, or a baseball...

Using Multiple Light Sources

Studio Flash Light Curciut

Once you gain control over the qualities and effects you get with a single light source, you'll want to graduate to using multiple light sources. Using several lights allows you to shape and mold the illumination of your subjects to provide a variety of effects, from backlighting to side lighting to more formal portrait lighting. You can start simply with several incandescent light sources, bounced off umbrellas or reflectors that you construct. Or you can use more flexible multiple electronic...

Sensor Cleaning

Those new to the concept of sensor dust actually hesitate before deciding to clean their camera themselves. Isn't it a better idea to pack up your 40D and send it to a Canon service center so their crack technical staff can do the job for you Or, at the very least, shouldn't you let the friendly folks at your local camera store do it Of course, if you choose to let someone else clean your sensor, they will be using methods that are more or less identical to the techniques you would use...

Creative Zone Flash

When you're using a Creative Zone mode, you'll have to judge for yourself when flash might be useful, and flip it up yourself by pressing the Flash button on the side of the pentaprism. The behavior of the internal flash varies, depending on which Creative Zone mode you're using. P A-DEP. In these modes, the 40D fully automates the exposure process, giving you subtle fill flash effects in daylight, and fully illuminating your subject under dimmer lighting conditions. The camera selects a...

Adding Circles of Confusion

Circle Light

But there are other factors in play, as well. You know that increased depth-of-field brings more of your subject into focus. But more depth-of-field also makes auto-focusing or manual focusing more difficult because the contrast is lower between objects at different distances. So, autofocus with a 200mm lens or zoom setting may be easier than at a 28mm focal length or zoom setting because the longer lens has less apparent depth-of-field. By the same token, a lens with a maximum aperture of f...

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,...

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...
