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 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...

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.

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...

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...

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,...

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...

Set a custom white balance

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...

Night and Low Light Photography

Canon Eos 450d Images Samples

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 challenge your exposure skills, but they also open a new world of creative challenge, enjoyment, and the potential for stunning images. Some events and stock photography also involve low-light scenes and nighttime shooting, so having a good understanding of how to get good results without excessive digital noise is important.

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...

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...

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...

Set White Balance Correction

Similar to White Balance Auto Bracketing, you can also manually set the color bias of images to a single bias setting by using White Balance Correction. The color can be biased toward blue B , amber A , magenta M , or green G in - nine levels measured as mireds, or densities. Each level of color correction that you set is equivalent to five mireds of a color-temperature conversion filter. When you set a color correction or bias, it is used for all images until you Note On the Rebel XSi 450D,...

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.

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...

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...

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. These settings determine not only the number of images that you can store on the media card, but also the sizes at which you can later enlarge and print images from the Rebel XSi 450D. 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...

Time The role of shutter speed

Shutter speed controls how long the shutter stays open to let light from the lens strike the image sensor. The longer the shutter, or curtain, stays open, the more light reaches the sensor (at the aperture and ISO that you've set). When you increase or decrease the shutter speed by one full setting, it doubles or halves the exposure. For example, twice as much light reaches the image sensor at 1 30 second as at 1 60 second. In daily shooting, shutter speed is also related to The ability to...

Choosing White Balance Options

White balance settings tell the camera what type of light is in the scene so that the camera can render colors accurately in images. Using white balance settings can help you spend more time shooting and less time color-correcting images. On the XSi 450D, you can choose one of the seven preset white balance options or set a custom white balance. Tip If you shoot RAW images, you can set or adjust the white balance in the RAW conversion program after the image is captured. Table 3.1 provides the...

Fluorescent and other light

Commonly used in offices and public places, fluorescent light ranges from a yellow to a blue-green hue. Other types of lighting include mercury-vapor and sodium-vapor lights found in public arenas and auditoriums that have a green-yellow cast in unfiltered uncorrected photos. You should set a custom white balance on the XSi 450D in this type of light or, if you shoot RAW, shoot a white or gray card so you can balance to neutral during conversion. 6.14 These red and yellow peppers were lit by...
