Hmm...I'm betraying my age but I've been using Photoshop since version 3.0. It came with my desktop scanner way back in 1994. I still use it today, almost daily, to create/edit artwork used in animated TV shows, and to create matte paintings for film and tv vfx work. I have a zillion other uses for Photoshop. I also use Photoshop to finalize artwork with other programs. Like my comics, for example, which are originally created using Clip Studio Paint. Or I'll use Photoshop to create artwork to rig and animate in programs like Moho Pro. Expert. (At least, by now, I hope I am) :) Yes, full time. Although Photoshop is only one of dozens of programs I use daily. To me, Photoshop is a powerful 'general purpose' program, so I'm not sure I have a favorite use for it. But after all this time, I still find brand new uses for the program.
