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...

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...

What Lenses Can You

The previous section helped you sort out what lens you need to buy with your XTi (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 Digital Rebel XTi. With the Rebel XTi, the compatibility issue is a simple one it accepts any lens with the EF or EF-S designation, with full...

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...

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...

Adjusting White Balance

I showed you how to adjust white balance in Chapter 3, using the XTi'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 Digital Rebel XTi 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...

Customizing White Balance

Back in the film days, color films were standardized, or balanced, for a particular color of light. Digital cameras like the Rebel XTi 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...

White Balance Shift and Bracketing

Amber Blue Magenta Green

White balance bracketing can be performed in any JPEG-only mode you can't use RAW or RAW JPEG . This form of bracketing is similar to exposure bracketing, but with the added dimension of hue. When you select WB SHIFT BKT, a screen like the one shown in Figure 3.10 appears. First, you turn the Main Dial to set the range of the shift in either the Green-Magenta dimension turn the dial to the left to change the separation of the three dots representing the separate exposures , or in the...
