If I understand this, when you take a picture witha digital camera, no matter what resolution setting you have it set at, it packs the same amt of pixels into the image. But why if I take a picture at 600x800 can't I increase the size of the picture without losing image quality? If the same amt of pixels are in that 600x800 as would be in an 2160x1440? I don't get it, you can scale down a large resolution picture and not lose quality, if you have a camera with sufficcient pixels, why can't you scale up? Thanks for the clarification. edit: Whoops, wrong forum, sorry. Please respond anyways __________________ __________________ Associates Degree in IS A+ Certified Studying for Network+

In other words, an 800x600 resolution is 800 pixels wide and 600 tall. So there is a significant difference in the number of pixels in a 2160x1440 (3,110,400 or 3.1 megapixel) image than in an 800x600 (480,000 or .5 megapixel) image. __________________
