Want to see how much more information is stored in a photo taken with a 6+ megapixel digital SLR? I took a few test shots with my new Digital Rebel at the highest jpeg quality setting, which is about 3000x2000 images (not a RAW or TIFF image). Here's a shot of my cat sitting in the sun, downsized to 750x500. And here's a 750x500 chunk of the original photo. Notice there's nary a hint of pixelation anywhere. After years of using 1 megapixel cameras and more recently a 3 megapixel camera, the stuff coming out of the SLR is unbelieveable.
I haven't printed anything with this camera yet but I bet prints from inkjets or ofoto are going to look superb given all the detail in these images.
