I had a little time yesterday to paint. This time I used a slightly different approach and worked on a white oil primed panel, instead of a reddish toned panel over gesso. (I primed with Gamblin's oil primer over gesso)
Over the white oil primed surface, I made a very detailed underpainting. This approach worked well and forced me to handle all my problems at the start. Next time though, I will use burnt sienna instead of red umber. The oil primed surface was nice for this, as it can be wiped back to white unlike gesso, which stains.
I also used real turps and put copal resin in the underpainting so it would tack up quickly and not interfere as much in the color layers.
Palette was the Vasari proprietary greys from Scott Christiansen...I didn't want to deal with color as much as drawing and composition. Time was limited and I worked large, so this enabled me to not have to mix colors so much.
