I just zipped a set of photos over to Walmart for printing (online upload and order, pick up in store). The photos looked fine to me on my calibrated monitor. When I picked them up, I was terribly disappointed. One set (4 prints) is totally over-sharpened and one of the prints looks like I tried to blow up a 10x20 pixel print into a 5x7." I sent files that were about 600kb in size, and had been cropped in Elements to 5x7 sizing (printed as 5x7) so that there would be no cropping issues. I use a calibrated monitor, and the pictures look great on my screen. This is the print that looked the worst. It is a fisheye image. The print of it looked like the rocks were disintigrating by the worst acid rain anyone's ever seen, it was too light and the sky looked pixel-ated (if that's a word). My questions are: 1. Does this picture look over-sharpened? 2. Were the files too small for 5x7? 3. Does the Walmart machine do further sharpening? 4. Is their machine trying to "auto correct" things that it shouldn't?
