After posting several pictures of my experiments in shading pictures with diluted solutions of ink, I was asked a lot how I do it. Instead of repeating the same thing each time, I thought I would spend an hour and make up this tutorial to give people the basics.

I hope this helps out. This is a very inexpensive method that has pretty nice results. Thanks go to Steve Gallacci for inspiring me with his excellent work with ALBEDO and FUSION.
