Have you ever wondered what a photo you’ve taken would look like if it were painted by a master like Monet? How about if it were taken by a maestro of photography like Margaret Bourke-White? Or maybe you’d like to try your hand at transforming an image with photo processing. Those are the kinds of things you can do to your digital snapshots with an iPad app called “PhotoCopier.” Software for turning digital photos into paintings or giving them the look of an assortment of film types — Kodachrome, Fujifilm and such — are common on the desktop.
