I found a wonderful article on Camera Resolution on PhotographyLife.com which by the way is a great site/blog on photography. They cover what camera resolution impacts as well as really what you get for each of them costly megapixels. I always find it insane that we keep going up in megapixels my new camera has 24 megapixels yet I have a beautiful poster in my house taken with a Nikon D2h which is a 4 megapixel camera. Enjoy the article and let me know what you think.
