There is now a major renaissance of painting technique, from the muddy alla prima (physical color mixing) to the more realistic Flemish or indirect method of glazing (optical mixing). And PS is ideally suited to capitalize on it. See Kahinde Wiley for just one example and the changes in his technique. It allows simplification of painting by nearly eliminating the expertise needed to get accurate flesh and other colors, namely, by using glazed layers of tube color thinned with medium. If not correct, that layer is wiped off the dry previous layer to begin again without loss, exactly analogous to the modification of layers in PS. This allows access by amateurs to achieve results previously only by very advanced/professional artists. In painting classes, nearly every student I see struggles, because the instructor has never had instruction in teaching amateurs, and tries to get them to do accurately in a few weeks what he/she has taken over 3 years to learn. Not going to happen. Many don't return. Also, instead of the long expensive training needed to learn accuracy in drawing the modello, a much faster, much more accurate modello is printed from PS to transfer to the panel, allowing the untrained amateur to achieve a pleasing likeness. The composition can be very quickly changed in PS, not in the sketch. Drawing instruction remains critically important in portraiture, to train depiction in Levels, but PS could greatly speed success and help prevent discouragement. Where Adobe can further help, make a more desirable product for the amateur painter, would be an app that would transform the Color Picker to show the nearest tube color from tables of a manufacturer's color charts. Maybe even suggest 3 colors that, glazed together, would closely approximate the picked color. Obviously there are many issues to be overcome, relating to monitor calibration, manufacturer variation, etc. but imo this would open up a large market for the amateur (esp portrait and still life painters), mean a greater demand for PS. Finally some of us do not trust the cloud or subscriptions. We want a disk or download that is ours, to upgrade when we feel a need.
