I'm working again with a technique, called "etching & aquatint", means I'm drawing on a metallic plate which is covered with some stuff (always forget what it's called, sorry ). Then I put the plate into an acid bath, which is etching my painting into the plate. When I apply ink on the etched plate, it's running into the etched lines, which can be printed via a press on paper. I can add depth with another material called aquatint to have "layers" and different levels of gray.
I really love the outcome of these! Plus I can sell them as affordable original artwork
