To do this I started with an original image at full size, then created scaled down versions at 50 percent and 25 percent in Photoshop. To help separate fact from fiction, I decided to take an engineering approach to do an analysis of how the resizing tools I have at my disposal really perform. It makes no sense to me how an image could get better on upsizing, but I do see how upsizing could improve to get closer to the original source image by with improved algorithms that understand what data is lost on downsizing. The skeptic in me sees source images that appear to be blurred with heavily sharpened after images which don’t tell the tale of what really happened. \We’ve all seen the ads that show incredible resizing that seems to recover tiny photos into something better than before, but honestly I don’t believe ads like that.
