This is the warm up, apples on black. They are getting easier. However, I am using a value finder, a red plastic thing you look through, which shows me the lighter value of the shadow side. Without it, I couldn't get it! I think I can train myself to expect that light, but on a mid value form I have trouble even seeing it. I am liking doing a warm up for 30-40 minutes each day, something about that term makes it seem like it doesn't really count, so there is no strain.
