What a silly question, those are the best. ;-) More seriously, the problem is most likely that you are looking at the images at 200%. Everything but 100% requires some kind of scaling, done by the image viewer. And most of them prefer speed over quality there, so the results will be different. The only way to compare images is looking at them at 100% so that no scaling is required at all. > Greets Tobias
