3 TERRIFIC TIPS! From Photographer & Pampered Chef, Gene Chavez:

• Whatever camera you own, even if it’s a Point & Shoot, ALWAYS set it at the HIGHEST resolution possible; i.e. Image Size = LARGE, Image Quality = Fine.  Or, DON’T try to get as many images possible on your Media Card.  Reason–you can always CROP a high resolution image to get the look you really want, and it won’t be pixelated.
• In the world of digital photography, you can always CROP-IN the rule of Thirds during your post-shoot processing–don’t waste time looking for the perfectly framed image when you’re behind the lens.
• If you’re looking to buy a Point & Shoot that has a long zoom capability, remember the difference between OPTICAL and DIGITAL zoom–Optical is much preferred.
