Sensor Technology

The 40D features a Canon-produced CMOS (Complementary Metal Oxide Semiconductor) image sensor. While Canon isn't the only camera manufacturer that uses CMOS sensors, it is the only company, at the time of this writing, that produces and markets full-frame, 35mm-size image sensors. Canon is also one of the few companies that designs and manufactures its sensors in-house for all of its digital SLRs. Sensors, of course, lie at the heart of digital photography. Digital cameras use either CMOS or...

Closeup mode

In Close-up mode, the 40D allows a close focusing distance and sets a wide aperture. It chooses One-shot drive mode and the Standard Picture Style. You can enhance the close-up effect of a close-up image further by using a macro lens. If you're using a zoom lens, zoom to the telephoto end of the lens when shooting in this mode. For the best images, focus at the lens's minimum focusing distance. The easiest way to determine the minimum focusing distance is to listen for the beep that confirms...

Full Auto mode

In Full Auto mode, the camera automatically sets the aperture, shutter speed, ISO, drive mode, autofocus mode, white balance, and Picture Style. In short, Full Auto mode provides point-and-shoot functionality. Because the camera sets everything, this appears to be a good mode for quick snapshots. However, the camera defaults to using the flash, even in scenes where you may not want it. In addition, the camera too often sets an unnecessarily aggressive ISO, usually starting at ISO 400, even in...

Cleaning the Image Sensor

Few early digital photographers managed to escape tedious hours spent spotting images. Regardless of how careful they were when changing lenses, inevitably dust particles some rivaling the size of digital meteors would quickly accumulate on the sensor. Of course, dust still accumulates on image sensors. The dust and spots come from external dust and clothing particles that fall into the chamber while changing lenses, and from dust or lubricants within the camera body that are dislodged by...

Stock Photography

At some point, almost everyone who has more than a passing interest in photography toys with the idea of making money from his or her images. And for those who do, their short list of ideas includes stock photography near the top. Stock photos fill the pages of popular newsstand magazines and brochures and grace posters in public places and billboards along the highways. Stock photography refers to existing images available for licensing by clients including advertising agencies, corporations,...

SRAW capture

The 40D also includes an sRAW image-recording quality option. sRAW is an apt abbreviation for Small RAW. These files, which are slightly larger than half the size of a standard RAW file, are approximately 7.1 MB while a full-resolution RAW file is 12.4MB. But sRAW files offer all the conversion advantages that standard RAW files offer including the ability to change key settings such as adjusting brightness, white balance, contrast, and saturation. You can also choose to shoot sRAW along with...

Characteristics of RAW Images

RAW capture allows you to save the data that comes off the image sensor with virtually no internal camera processing. Because the camera settings have been noted but not applied in the camera, you have the opportunity to make changes to key settings such as image brightness, white balance, contrast, and saturation after the image is captured. The only camera settings that the camera applies to a RAW image are ISO, shutter speed, and aperture. During RAW image conversion, you can make...

Zoom lens disadvantages

Although zoom lenses allow you to carry around fewer lenses, they tend to be heavier than their single focal-length counterparts. Mid-priced, fixed-aperture zoom lenses tend to be slow, meaning that with maximum apertures of only f 4.5 or f 5.6, they call for slower shutter speeds that limit your ability to get sharp images when handholding the camera. Some zoom lenses have variable apertures. A variable-aperture lens of f 4.5 to f 5.6 means that at the widest focal length, the maximum aperture...

Night and Low Light Photography

If you're ready to challenge your photography skills, shooting low-light and nighttime images is a great way to do it. Night and low-light images not only expand your understanding of exposure, but they also open a new world of creative challenge, enjoyment, and the potential for lovely results. Some event assignments and stock photography also require you to shoot in low-light scenes and at nighttime, so having a good understanding of how to get good results without excessive digital noise is...

Table Travel Photography

Setup In the Field For the picture shown in figure 9.33, the objective was to find a shooting position that allowed the photographer to capture the tower and the street lamps that are characteristic of the area.

Portrait mode

In Portrait mode, the 40D sets a wide aperture that makes the subject stand out against a softly blurred background. The 40D also switches to Portrait Picture Style to enhance the subject's skin tones. This mode works well for quick portraits in good light. In low-light scenes, the camera automatically fires the flash, which may or may not be the effect you want in the portrait. While flash can create an unnatural and hard look for portraits, the flash performance on the 40D is much improved...

Wedding Photography

Today's wedding photographer is likely to be an ace at applying a photojournalistic shooting style coupled with a dash of fashion and glamour shooting all mixed with a little traditional portraiture for good measure. For some of the top wedding photographers, the goal of every wedding is to produce fine-art imagery that will stand on their own years from now as classic photos. Creating time-tested, artistic photos is a lofty goal for a shooting specialty that can be marked with the height of...

Using Wide Angle Lenses

A wide-angle lens is great for capturing scenes ranging from large groups of people to sweeping landscapes and underwater subjects, as well as for taking pictures in places where space is cramped. The distinguishing characteristic of wide-angle lenses is the range of the angle of view. Within the Canon lens lineup, you can choose angles of view ranging from the fisheye lens, which offers a 180-degree angle of view, to the 35mm, which offers a 63-degree angle of view, not counting the 1.6X focal...

Exposure Compensation

The third way to modify the standard exposure on the 40D is by using Exposure Compensation. Unlike Auto Exposure Lock and AEB, which serve well for specific shooting scenarios, Exposure Compensation enables you to purposely and continuously modify the standard exposure by a specific amount up to plus minus 2 f-stops in 1 3-stop increments or in 1 2-stop increments via C.Fn I-1. Scenarios for using Exposure Compensation vary widely, but a common use is to override the camera's suggested ideal...

Lens controls

All Canon lenses provide both autofocus and manual focusing functionality via the AF MF (Autofocus Manual Focus) switch on the side of the lens. If you choose MF, the 40D provides focus assist, shown in the viewfinder, to confirm sharp focus. When sharp focus is achieved, the Focus confirmation light in the viewfinder burns steadily and the camera emits a focus confirmation beep. 1.5 Bottom camera covers, compartments, and sockets Focusing Distance Focusing distance range Zoom ring scale...

Table Wedding Photography

Setup In the Field Figure 9.36 is one of the formal shots where color helps form the lines created in the image to provide good eye direction and movement through the subjects. Additional Considerations Before the ceremony begins, scout out shooting positions and leave a note or object on a seat to reserve it. Some couples do not want the ceremony photographed and others want it photographed but without the use of flash. Be sure you know the couple's wishes and requirements before the ceremony...

Viewing and Playing Back Images

Viewing, or playing back, images goes beyond a quick glance to see if the image exposure and composition is acceptable. Image review most often includes magnifying the LCD preview to check for sharpness, reviewing the brightness (luminance) histogram for localized areas of overexposure, and or reviewing the color histogram to check color saturation, gradation, and white-balance bias. And with this unprecedented ability to gauge exposure and composition on the spot, image evaluation can quickly...

Tungsten light

Tungsten is the light commonly found in household lights and lamps. This light has a warmer hue than daylight and produces a yellow orange cast in photos. In some cases, the distinct yellow hue is valued for the warm feeling it lends to images. Setting the 40D to the Tungsten White Balance setting retains a hint of the warm hue of tungsten light while rendering colors You can learn more about setting custom White Balance and using white or gray cards at www.cambridgeincolour. com tutorials...

Manual mode

Manual mode, denoted as M on the Mode dial, gives you full manual control. You set both the aperture and shutter speed based on the exposure level meter shown in the viewfinder and on the LCD panel. This mode is useful in a variety of shooting scenarios including shooting fireworks, astral photography, for some studio shooting, when you want to intentionally underexpose or overexpose the scene, or when you want a consistent exposure across a series of photos such as for a panoramic series. In...

To check the sharpness of several images, turn the Quick Control dial to move through...

Understanding the Focal Length Multiplication Factor

Schnauzer Dog Pictures

The 40D 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. The angle of view for all lenses you use on the 40D is reduced by a factor of 1.6 times at any given focal length, giving an image equal to that of a...

Selecting a Metering Mode

The 40D offers a full menu of metering options with new algorithms for more consistent exposure and high accuracy for highly reflective subjects. The default mode is the 35-zone through-the-lens (TTL) full-aperture reflective metering system that is linked to the selected AF point or points. Depending on your exposure needs, you can also use Partial, Spot, Center-weighted Average metering modes. The 40D metering options, available only in Creative Zone modes, are as follows Evaluative. This...

Live View using autofocusing

With Live View shooting, you can focus either manually or by using the camera's autofocus system. With autofocus, by necessity, the reflex mirror must remain locked up while the camera is providing a live view. When you want to focus, the mirror must go down momentarily. Autofocus is initiated by pressing the AF-ON button on the back of the camera, provided that you enable it using Custom Function (C.Fn) III-6.

RAW capture

RAW files are in a proprietary format that does not discard image data to save space on the CF card. Because the images are a proprietary format, they can be viewed only in programs and on operating systems that support the file format. Unlike JPEG images, RAW capture saves the data that comes off the image sensor with minimal internal camera processing. Many of the camera settings have been noted but not applied to What Is Bit-Depth and Should You Care A digital picture is made up of many...

About Live View Shooting

The concept of the camera being able to hold the shutter open to give you a realtime view of the scene and yet pause long enough to focus is impressive in terms of technology. And even more impressive is the quality of the live view that the 40D provides, which is smooth and detailed. To create this live view, Canon engineered an electronic first-curtain shutter that enables shooting while the mechanical shutter is completely open. To give the detailed view, the camera uses a high-speed...

Cleaning the sensor manually

With the self-cleaning sensor combined with Dust Delete Data, the likelihood or need to manually clean the sensor drops dramatically. Occasionally, however, you may find it necessary to clean the sensor. Once you have the product that you'll use to clean the sensor, do the following Ensure that the camera battery is fully charged. You can't use the optional battery grip with AA batteries in it to clean the sensor. Find a place indoors away from drifting lint, dust, pets, and so on, that has...

Nature and Landscape Photography

Setup In the Field In figure 9.18, patches of fog inspired me to capture this scene. I took the window screen off the window and hung out of an upstairs window to capture this foggy forest scene. Additional Considerations Because such a wide variety of scenes is possible with landscapes and nature, the best advice is to trust your eye to set up and compose images. Try to exclude distracting utility wires, road signs, and trash within the scene. Shoot from a variety of low, high, and eye-level...

Lens extenders

For relatively little cost, you can increase the focal length of any lens by using an extender. An extender is a lens set in a small ring mounted between the camera body and a regular lens. Canon offers two extenders, a 1.4x and 2x, that are compatible only with L-series Canon lenses. Extenders can also be combined to get even greater magnification. For example, using the Canon EF 2x II extender with a 600mm lens doubles the lens's focal length to 1200mm before applying 1.6x. Using the Canon EF...

About Color Spaces

A color space defines the range of colors that can be reproduced and the way that a device such as a digital camera, a monitor, or a printer reproduces color. Of the two color space options offered on the 40D, the Adobe RGB color space is richer because it supports a wider gamut, or range, of colors than the sRGB color space option. And in digital photography, the more data captured, or, in this case, the more colors captured by the camera, the richer and more robust the file. It follows that...

Table Autofocus and Drive Modes

Drive Mode One-Shot AF AI Focus AF AI Servo AF In One-Shot AF mode, the camera must confirm accurate focus before you can take the picture. If you're using Evaluative metering, exposure is also locked at the selected AF point. If the subject moves, the AF mode automatically switches from One-shot AF to AI Servo AF to track and focus on the moving subject. The camera focuses on the subject and maintains focus during subject movement. The exposure is set at the moment the image is captured....

Approaches to using various White Balance options

Because the 40D offers three basic approaches to setting white balance, you may find that you use different approaches in different shooting scenarios. Following are examples for using each. Using preset white balance settings. For outdoor shooting, especially during clearly defined lighting situations such as bright daylight, an overcast sky, or shooting in Getting Accurate Color with RAW Images If you are shooting RAW capture, a great way to ensure accurate color is to photograph a white or...

To shoot in Live View using autofocus, follow these steps 1. With the camera set to a Creative Zone mode, set the ISO, aperture, and or...

Inspiration

Choose a place that gives you a unique visual or emotional sense. For example, if you find a scene that exudes tranquility, try different positions, focal lengths, and foreground elements to help convey the sense of peace. As you take pictures, look both at the overall scene and the components that make it compelling. Isolate subscenes that make independent compositions or can be used as a center of interest for the overall scene. As you look around, ask yourself questions such as whether...

About autofocus points and autofocus modes

The 40D sports a new autofocus (AF) sensor with nine AF points etched in the viewfinder. The selected AF point or points establish the point of sharpest focus in the image. Canon's high-precision AF points are suited for use with fast lenses. These AF points are sensitive to vertical line detection and to horizontal line detection, which is critical to achieving sharp, accurate, fast focus. On the 40D, all nine AF points are cross-type and AF sensitivity is Exposure Value (EV) -0.5 to EV 18 at...

Auto Exposure Lock

As noted in earlier sections, Canon sets exposure to the AF point that you select. This approach is fine as long as the area of critical exposure falls within the point where you want sharpest focus. Often, however, that's not the case. For example, if the light falling on the model for a portrait has a bright spot 2.10 With AE Lock, the highlights retained much more detail in this image, but the shadows went to black quickly. I realized that this will happen and knew that I would need to bring...

Erasing Images

Erasing images is a fine option, but it is an option to choose only when you know without a doubt that you do not want the image you're deleting. Use it with caution. From experience, I know that some images that appear to be mediocre on the LCD often can be salvaged with judicious editing on the computer. Before you erase images, remember that you cannot recover them. Remember also that even with the large LCD monitor, you're still looking at a tiny version of your images. I find that it's...

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...

If you like to organize images by media card, Auto Reset may be a useful option. With Auto Reset, file numbering restarts each time you insert a newly formatted CF card. Folder numbers begin with 100, and file numbering begins with 0001, unless the CF card contains a previous image, in which case, numbering begins with the highest file number in the highest numbered folder on the CF card. However, with the Auto Reset option, multiple images will have the same filename. Because of duplicate...

ISO Range Expansion and CFn options

The 40D offers a default ISO range from 100 to 1600 in 1 3-stop increments. You can also adjust the ISO in 1 2-stop increments using C.Fn I-1. The ISO range can be expanded to include ISO 3200 that is displayed as H in the viewfinder and on the LCD panel. Note Manual ISO adjustments and using Custom Functions are available only in Creative Zone shooting modes. With the 40D, you can choose to reduce or eliminate noise in long exposures by a dark frame. To totally or virtually eliminate noise,...

Customizing My Menu

Given the proliferation of menus on the 40D, and given that in an average day of shooting you may use four or five menus consistently, customizing the My Menu option is the easiest way to get to the most frequently used items quickly. Just as with the C mode registration, My Menu lets you select and register your most often used menu items and Custom Functions for easy access. In particular, as you become a fan of Custom Functions, you can sidestep figuring out the Custom Function grouping...

Selecting a Drive Mode

In Creative Zone modes, you can choose among three main drive-mode options on the 40D Single, Continuous Shooting, and Self-timer modes. You can choose a drive mode in Creative Zone shooting modes. Note ln Basic Zone modes, the camera automatically chooses the drive mode, but in most modes, you can optionally choose the 10-second Self-timer mode. Single Shooting. In this mode, one image is captured with each press of the Shutter button for up to 3 frames per second fps . High-speed Continuous....

Manual Reset

The third option is to manually reset file numbering. With this option, a new folder is automatically created with the next higher folder number than the last, and file numbering restarts with 0001. Subsequent images are saved in the new folder. After the manual reset, whichever file-numbering method you previously used Continuous or Auto Reset takes effect when begin shooting again. Unlike other EOS cameras, the 40D does not offer a direct way to create multiple folders on the CF card. In the...

Setting the Date and Time

While setting the date and time seems like a basic task that photographers would do first when setting up the 40D, I include it here for those who want to begin setting up a standard workflow. If you're new to digital photography, you may have heard the term workflow and wondered why it's important. As the term suggests, workflow means setting up and sequencing your work so that consistent standards are applied and so that all steps from shooting, through editing, printing, and archiving are as...

Registering a User Defined Picture Style

With an understanding of the settings you can change with Picture Styles, you can create a Picture Style to suit your specific preferences and workflow needs. Each style that you create is based on one of Canon's existing styles, which you choose. And because you can create three User Defined Styles, there is latitude to set up styles for different types of shooting venues. For example, to create a set of styles for wedding shooting, one style could be a variation of the portrait parameters...

Metering Light and Reflected Light

A camera's reflective light meter sees only gray, and it measures light that is reflected back to the camera from the subject. As the meter looks at a scene, it sees tones ranging from black to white and all shades of gray between. The meter measures how much light these shades of gray, black, and white reflect back to it. Objects that are neutral gray, which is an even mix of black and white, reflect 18 percent of the light falling on them and absorb the rest of the light. In the...

Program AE

Program AE mode, denoted as P on the Mode dial, is an automatic but shiftable mode. Shifting means that you can change the aperture by turning the Main dial, and the camera automatically sets the shutter speed to an equivalent exposure. For example, if the camera initially sets the exposure at f 2.8 at 1 30 second, and you turn the Main dial one click to the left to shift the program, the exposure shifts to f 3.2 at 1 20 second. Turning the Main dial to the right results in a shift to f 4.0 at...

Landscape mode

In Landscape mode, the 40D chooses a narrow aperture to ensure that background and foreground elements are acceptably sharp and that the fastest shutter speed possible, depending on the amount of light in the scene, is used. This mode works well not only for landscapes but also cityscapes, and for portraits of large groups of people. In lower light, the camera uses slower shutter speeds to maintain a narrow aperture for good depth of field and increases the ISO. As the light fades, watch the...

Fn IV Operation Others

The specifics on option numbers and names along with a description can be found in Table 4.9, for your quick and easy reference. C.Fn IV-1 Shutter button AF-ON button. This function changes the function of the Shutter button and the AF-ON button in starting and stopping autofocus and metering. C.Fn IV-2 AF-ON AE lock button switch. This function swaps the function of the AF-ON button and the AE...

Creating an Efficient Workflow

When workflow became a buzzword several years ago, it typically encompassed the process of converting and editing images one at a time or several at a time. Since then, however, the concept of workflow has expanded to include the process from image capture to client handoff, often including prepress settings, that ensures image quality and consistent settings that meet the client's needs and specifications. While workflow varies depending on your needs or the requirements of the client, here...

Set a custom white balance

Canon Eos 500d Men Green

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 or sRAW 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 used when you set the custom setting. It is relatively...

Exploring Flash Technology

Both the onboard flash and Canon's EX-series Speedlites employ E-TTL II technology. E-TTL stands for Evaluative Through-the-Lens flash exposure control. E-TTL II is a flash technology that receives information from the camera including the focal length of the lens, distance from the subject, exposure settings including aperture, and the camera's built-in evaluative metering system to balance subject exposure with the ambient light. In more technical terms, with E-TTL II, the camera's meter...

Macro photography tips

When photographing subjects with patterns, use a position that creates a strong diagonal line to create direction and motion in the composition. Make the most of lighting. If you want to emphasize depth in textured subjects, use strong side light that rakes across the subject. Or if you want controlled, focused light, you can fashion a modifier to reduce the breadth of light from a Speedlite. For example, one photographer fashioned a narrow snoot by using black...

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. Architectural photography is about capturing a sense of place and space. The challenge with the 40D, given the sensor size, is...

Highlight Tone Priority

Highlight Tone Priority is designed to improve or maintain highlight detail by extending the range between 18 percent middle gray to the maximum highlight tones, effectively increasing the dynamic range. Thus the gradation between grays and highlights is finer, and that reduces the blown highlights. This option, however, limits the ISO range from 200 to 1600 and can increase noise in the shadow areas slightly. Highlight Tone Priority takes advantage of the higher ISO baseline so that the image...

Applying Dust Delete Data

After acquiring the Dust Delete Data, you can use Canon's Digital Photo Professional program to apply the data to either JPEG or RAW images. Be sure that you've installed Digital Photo Professional from the Canon EOS Digital Solution Disk included in the camera box. To apply Dust Delete Data in Digital Photo Professional, follow these steps. 1. Start Digital Photo Professional, and then navigate to the folder that contains images with Dust Delete Data appended. If you just obtained the data,...

Specify a color temperature

Setting the white balance for a specific color temperature is the easiest way to get neutral color in the least amount of time. The caveat, of course, is that you must know temperature of the light to get good results. In most studios, the light temperature is known and it can be easily dialed in to the 40D. And if you're fortunate enough to have a color-temperature meter, then you can use this White Balance option with abandon. To set a specific color temperature, follow these steps 1. Press...

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...

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...

Action and Sports Photography

Anyone who shoots action and sports events knows that a fast camera is essential for capturing the energy and critical moments of the action. With a burst rate of approximately 75 JPEG and 17 RAW frames in High-Speed Continuous Drive mode combined with smart buffering, the 40D delivers beautifully for action shooting. The focal length multiplication factor of 1.6x brings the action in close with telephoto lenses. For example, using the Canon EF 70-200mm f 2.8L IS USM lens effectively provides a...

Use White Balance Auto Bracketing

Given the range of indoor tungsten, fluorescent, and other types of lights that are available, the preset White Balance options may or may not be spot-on accurate. Alternately, you may prefer a bit more of a green or blue bias to the overall image colors. With the 40D, you can use White Balance Auto Bracketing to get a set of three images each with - 3 levels in 1-step increments. White balance bracketing is handy when you don't know which bias will give the most pleasing color, or when you...

Obtaining Dust Delete Data

For larger, sticky dust particles, the camera can determine the size and location of dust when you take a picture of a white piece of paper. Although you take a picture, no image is recorded to the CF card. Using the picture of the white paper, the 40D maps the coordinates of dust particles that are stuck to the filter and creates a very small data file that is appended to images. To erase the dust, you use Canon's Digital Photo Professional included on the EOS Digital Solution Disk . Appending...

Choosing and Customizing a Picture Style

Canon 50d Portrait Picture Style

The name Picture Styles sounds like a marketing-motivated set of optional features for the 40D. Regardless of the naming, it's important to realize that the 40D attaches a Picture Style to every image that you shoot. In other words, Picture Styles form the foundation of how the camera delivers tonal curves, color rendering, color saturation, and sharpness in the final image. The 40D offers six Picture Styles, which are detailed in Table 3.2, and it uses the Standard Picture Style as the default...

Flash Exposure Lock

The second way to modify flash output is by using Flash Exposure Lock FE Lock . Much like Auto Exposure Lock AE Lock , FE Lock allows you to meter and set the flash output on any part, typically the point of critical exposure, of the subject. In figure 8.5, I photographed the same scene as shown in figures 8.2, 8.3, and 8.4, only here I used FE lock. 8.5 The flash exposure is locked on the highlight to the left of the bottle just under the top wrapper resulting in a darker exposure but with...
