On the right, there is a more refined image of an imaginary pilot. I used a dark brown ground, ( burnt umber). Then painted in thin turps diluted white/orange mix the general features. Later after a few days to dry, added thicker oil/turps mixed medium layers to give the skin tones more depth. The last layers were only diluted with linseed oil. As the piece progressed, I found it necessary to use thinner and thinner brushes, finishing off with a No. 4 Dalon round.
There is a considerable shift in approach when working on oil, turps layers a can be a bit fragile, it is too easy to lift the paint off with subsequent brushing. It is therefore best to let the piece dry at this stage. This can mean you finish any possible work on the picture in a short time, thus freeing up time to work on another. this way your workspace can contain a number of pieces at various stages of completion. In a painting session you may be able to work on a number of pictures. |
