Some replies here are correct, and some are not. Yes, you need 3.2 mp or so to reach photo quality, BUT, the fact that some censors are rectangular while the lens is round, cause loss overall in "effective Pixels", also there are other attributes to consider. Anything over 6-8 mega-pixels is a waste, unless you intend to make duratrans displays or posters, ad signs, etc.

Bottom line, you DO want at least a 6mp or better camera, with a large as practical lens, to compensate for physical AND electrical characteristics of digital cameras, and the Canon Powershot S3 is an excellent choice, it has 12X zoom, equivalent to a 400mm lens, and has super macro, you can get within 0 inches, now that rocks!! :)

Answer 2

The higher the number of megapixels, the sharper and more detailed the image quality is.

Answer 3

A megapixel is an increment of picture quality. A pixel is a small square in a picture that is put together with millions upon millions of other pixels to make a picture. The more megapixels you have the more you will be able to zoom in without seeing all of those squares (pixels) to balance budget with quality go with a digital camrea with about 6-8 megapixels

Answer 4

Higher than 3 megapixels is only important if you intend on enlarging the picture to bigger than 8x10.

For regular sized pictures 3 megapixels is more than enough resolution.

Answer 5

the higher the megapixel the larger size picture you can print or order. Anything over 6 is a waste of time and money, also when you look at cameras do not look at digital zoom it means nada and often places will try to sell you on it. If it is a new camera I recommend one of the well know brands and not one of those cheap ebay knock-offs that say they are 12 megapixels. Good luck with your camera.

Answer 6

more megapixels, better quality.

I suggest 3.8 or more

PS: low res cameras can take up more room
