The more I do it, the more I realize that it's only now that I'm really serious about painting. Alla Prima's book has taught me things I wasn't even aware of. My biggest challenge is to identify value and hue with accuracy. I think I'll make myself 5 punched card of 5 different values, from white to black. So I can evaluate on the scene by looking thru the punched hole, what is the range of the value I'm seeing.
