Posterization is the process of separating a image in to discrete areas of
brightness and then changing those areas to a solid shade. It can be done in
seconds now with image editing software. But back in the "old" days, it
required a large number of steps in the darkroom. Separate high-contrast
negatives and positives must be made for each step of brightness (five, in this
image). These must then be combined in pairs and aligned as closely as possible
over the photographic paper. An exposure for each step is made individually.
This image took me approximately seven hours to produce. I decided it was much
too time consuming to explore any further. But I do enjoy this picture.
