Working with old photographs

10 years ago I made a series of approximately 50 black and white photographs. I printed them myself, using a gelatine silver printing process. The photographs show different setups of my large Cubicles installation I started as an art student. 

I still work with these Cubicles and each time I show them I produce more.

Recently I've been trying to work these photographs. Amongst the 50 photos I found this self portrait and started working on it with brush and ink. I'm not sure yet what these will become, but I will work on a couple of them to find out.
