Did you ask a question? The best one for you depends on what you will use it for. Anything above 5 megapixels are usually meant for the advanced hobbiest or pros. If you just want point & shoot prints get 3 - 5 megapixels. Does that somewhat answer the question that was assumed?
and life goes on...
My wife brought home ?The beginner?s Guide to Digital Photography?, a 12 page free booklet she picked up at Costco. It is printed by Costco in association with the Photo Marketing Association and the Digital Imaging Marketing Association.
Page two is, ?What?s the deal with megapixels and resolution?? and a table
#of Pixels Print Size
Less than 1 Megapixel
Screen resolution good for emailing
1 Megapixel 4-by-6-inch prints
2 Megapixel 5-by-7-inch prints
3 Megapixel 8-by-10-inch prints
4 Megapixel 11-by-14-inch prints
5 Megapixel 16-by-20-inch prints
There is no mention of cropping because this is a beginner?s guide.
