The man is right. The Fuji Frontier processors that are popular in many photofinishing shops take a digital image (or scan a film image at high resolution) and then use lasers to expose color photographic paper and chemical wet processes to develop it. The results are very good, and the same machine can be used to make anything from 4X6 to 20X30 prints by just switching magazines and pushing a couple of buttons. As noted above, several other manufacturers of photofinishing make comparable equipment.
