Looking at digital cameras I get confused about megapixels versus picture quality. I have noticed that taking smaller pics uses less pixels (ie. 640 x 480 = .3M = 4 x 6 in. pic). Taking larger pics uses more pixels. I find that the ratio of pixels stays the same when changing the size which makes me think that all the pics of different sizes will have the same quality. Of course, I realize that having a higher megapixel rated camera allows you to take those larger pics. So if someone is satisfied with taking 4 x 6 prints those expensive 6 megapixel cameras aren't really worth it (everything else being equal like zoom or other goodies). Now, if someone were to double the size of a pic (after taking the pic) does so without increasing the pixel count and make the pic look worse, will halving the size keeping the same pixel count make it look better by incresing the pixel density? Please reply to all my comments. Thanks.
