I'm getting back to painting, trying to put the lessons learned in my life drawing classes back into my painting, I've been studying the work of Caravaggio, his use of light and dark to create drama in a painting. I started by painting the whole canvas with burnt umber, I think this is a better way to start a painting, get all the intimidating white canvas covered, this makes it easier to build up the skin tones and it acts as a mid tone.
