Whether you're shooting with an introductory camera, like the Canon PowerShot G3, or an advanced unit, like the Canon Digital Rebel XT, you can take advantage of Canon's powerful in-camera processors known as DIGIC. The DIGIC system has helped millions turn out brilliant images time and again, and it has won the praise of top industry insiders and impartial consumer reviewers alike.
If you're an owner of a Canon EOS 300-D, 20-D, or other Canon digital SLR model, you might want to consider supplementing your lens collection. Dozens of attachments are available, ranging from cheap plastic ones that cost around $10 to astronomically expensive add-ons, such as the ES 600/4L IS USM, which cost thousands of dollars.
The physics of improving your field of view can get quite complicated, especially when adding on lenses to your digital camera. If you shoot in a lot in dimly lit conditions, the inexpensive kits which come with the Canon Rebel and Rebel XT may be insufficient for your needs. On the other hand, if you're simply taking vacation shots, family pictures, or slow-action captures, you can go ahead and employ the autofocus without worry.
One of the advantages to shooting with a Canon digital SLR is that you can manipulate your images after the fact with a computer program, like Adobe Photoshop. You can heighten brightness, bring out certain background reliefs, resize, magnify, add backgrounds, and even crop down your file sizes. Since most Canon digital SLRs don't come with capacious memory cards, you likely want to get a CompactFlash card to store your run off photo data.
