Mac classics: Twenty one years later, still using Photoshop | Macworld: Photoshop won that battle and over the subsequent 20-plus years kept winning the war. In that time, I've used every release. I used it to edit photos and figures for countless articles and books. The latter included three editions of Real World Scanning and Halftones, a book about the process of working with images from analog to digital and back again onto press. That topic became superannuated as the publishing industry shifted from imagesetting in service bureaus (using bluelines and color proofs for prepress checks) to plate-setting in printing plants (using PDFs instead).
