I have been testing a process in which I transfer images from a photo-copy or printed image onto canvas or other surface. This is done with a layer of matte gel medium, then rubbing off the excess paper. Somewhat time-consuming, but it achieves a stunning effect if done properly.
The top image was taken from a digital photo-manipulation that was printed off about 10 years ago. The bottom image was mostly painted the traditional way (torso and wings), the head was extracted from a photo copy of a literature book that I had kept since high school (Mr. Hyde).
