I haven't been too motivated to get out in the cold much this winter for photo shooting, so I've been doing some studio work. Most of this has been experimental and for learning, more than for creating great photographs. Practicing craft.
Also, I've been using this time to read a lot about photography and photographers. It's been a kind of independent study college curriculum (self-designed) and has included a lot of theory and visualization, or eye training. Interesting stuff.
