On the left: done before the Mel Stabin workshop; on the right: after.
Forgot to mention, and I'm sure it makes a difference--everyone always says it does, anyway--that at the workshop, and at home since, I've been painting standing up, rather than sitting, as I always had before.
More bouys. These first washes look a little to light to me; Mel says you should try to get the value right on the first go. Now I'll end up going back in and lose some of the freshness.
