I did print the two images a bit differently. The background of the caffenol print has a bit less exposure than the background of the regular print so it is a bit flatter. I was lighting the background but I could have backlit the head to try to get better separation.

In person I find it hard to choose between the two but I do really like the look of the caffenol. My scan might be a little too brown but it comes across with a nice skin tone for a black and white print. I'm thinking of some projects that would lend themselves to this look.

The subject (my brother) liked the caffenol version better.
