This seems relevant:
"My sketching is the same way. I don't know a scapula from a sternum but when I venture
out into the world with my sketch book, I am able to distill my impressions into a oneframe
story that totally tells my version of what I saw. When my wife Dee and I go on a
vacation, she takes the photos and I sketch. She records the facts—I record the truth."
-- Walt Stanchfield, Drawn To Life
