If you're new to digital photography (welcome aboard!), Canon has a nifty little site that discusses all the basics about your digital camera (regardless of the brand) and how to take great pictures.

Some of the topics covered are:

• Bright & dark shots
• Controlling depth of field
• Freezing or blurring motion
• ISO speed effects
• Creating depth
• Setting image quality
• Focusing a moving subject
• Shooting dark subjects
• Shooting bright colors
• Using white balance

Again, this site is mostly for beginners, but there may be some interesting tips for hobbiests who simply refuse to read their camera manual! :-)
