This weeks challenge was to paint old Abe in either of three ways. I chose using Ultramarine Blue and Burnt Umber with Permalba White for adjusting the tones of the painting. (Taking the photo of the painting still wet continues to createn reflection issues. The bluish area on the right side of the head is really a deep value.)
Well ok he looks like a cross between Abe Lincoln and Pierce Brosnon, what's wrong with that? Maybe you see someone else there instead. All in all not being a portrait artist, I think it came out ok.
I first mixed a large batch of equal parts Ult blue and Burnt umber. Layed in the sketch with this mixture wiping out with a rag for the lights and using less turp for the darks. When I got an image that looked half human, I started adding variations of the white to this mix to do the overlay. It really was fun to do.
