I teach Photoshop to designers. I am much more pragmatic than spiritual but I am also trying to get them to transform from doing what they know and think they “have to” be able to do to thinking about the process of using Photoshop as a tool to explore what is possible in design without being constrained by what has been done before. I do teach techniques–I have to or I would fail in my primary aim, which is to accustom fingers to using Photoshop.
I stress file structure a lot to encourage people to build libraries of parts they can recombine in many ways (or at least edit without loss at any point in the future) but it is really a different way of looking at making digital art. I try to get the students to think about creating something new and just digitizing old methods of working.
