Question

A stock photographer will want a camera with at least how many megapixels?

Answer 1

Well, an 8.5 by 11 inch at 300 dpi is 8,415,000 pixels, or almost 9 megapixel. That is about the minimum. For larger use, more megapixels are needed. It really depends on the intended use.

Answer 2

Oh, and the more there is is to start, the easier it is to keep quality with edits.

Answer 3

Well to be honest. I don't think that mpx will matter must for your stock photography. You better change the technology. A DSLR with decent megapixel (12 or above) censor will do a great job.
