Like many visually creative people, I use Photoshop. Not that there's a lot of choice in the matter; it is pretty much the only respected player in the game right now. It's annoying, then, that Adobe has thrown out a dubious marketing structure with its new "Creative Cloud".
Like many artists, I don't exactly get to work in luxurious surroundings all the time. Unfortunately, because of the occasional mess and odors from the materials used (and a lack of extra rooms in my house), airbrushing is relegated to a generous part of the garage on a custom-built mobile platform. This means that I'm at the mercy of the temperature gods.
