I've been reading up on the various methods of achieving depth and lighting with oils. One of the things I read involved doing the underpainting in the opposite spectrum of the finished painting ... if you want a warm finish, do the underpainting in cool colors and vice versa.
The current oil painting is, for all extents and purposes, a still life. Yeah, there are goblins in among the grapes but its a still life. The grapes are lovely green things that glow even in the photos I took (which reminds me, don't spend hours setting up a still life of fruit to photograph without warning the Boy about what you are doing. My grapes kept getting moved and eaten and I couldn't figure out what was going on).
Here's the current work in progress.
Still working on the underpainting. Its all cadmium yellow and glazes of burnt sienna.
Underpainting, all but the final layer to darken the shadows.
Finished underpainting
First layer of oils. I've just started the oil layer in burnt umber and some god awful shade of green.
