Many of them come with software for creating raw files from the saved images, no?
I don't know if they do or not. If the saved image is jpg the quality is limited no matter what you do with it. Really about 4 megapixels is all the camera is using. You can't make chicken salad from....
"I do not aim with my hand; I aim with my eye. He who aims with his hand has forgotten the face of his father.
I do not shoot with my hand; I shoot with my mind. He who shoots with his hand has forgotten the face of his father.
I do not kill with my gun; I kill with my heart. He who kills with his gun has forgotten the face of his father."
In short a 10 megapixel camera is more than enough for most people who up to 16x20 prints. More megapixels will allow you to crop better after the fact for the most part. Raw is usually not "better" out of the camera because you need to post process it while with JPG you can let the camera do that for you.
