I know that higher megapixels is better visiual quality, but specifically how good is the quality for a set of gigapixels. I dont' think i can afford a 2.2megapixel camera, so i might be forced to by a 1.3 (less tahn $200 budget). I don't need professional quality, but I also don't want a loss of quality. Will 1.3 megapixels be enough? and what does it mean in terms of resolution?
