While some 5-megapixel models might linger in stores, most new cameras now offer at least 6 or 7 megapixels, and a growing number of point-and-shoots, or cameras with built-in lenses, offer 10 and 12. Six megapixels provide all the resolution most people need. If you often crop or dramatically enlarge your images, get at least 7 megapixels.

If you need high resolution and impeccable quality, choose one of the high-resolution compacts or SLRs that had excellent print or image quality in our tests. Shooting at a higher resolution without using a compressed format such as JPEG can fill your memory card and hard drive more quickly. This year, though, more cameras can record on a new, higher-capacity card known as SDHC. If high resolution isn't critical, a model in our Ratings with very good image quality and 6 or 7 megapixels of resolution should be fine.

Among point-and-shoot cameras, the highest ISO light-sensitivity setting has generally been 400, too low to make sharp handheld shots in dim light without a flash. Some modestly priced models have begun featuring settings of 1600 or even 3200, but results can be grainy and noticeably worse than those shot at equivalent settings using SLRs and the priciest point-and-shoots. If you're attracted to a particular subcompact or compact because of its high ISO settings, check its performance in our Ratings (available to subscribers) and make sure you can return it at no cost if its low-light results are disappointing.
