the enlarger was made from a spare lens I got given along with the camera (from a pawnbroker), it is difficult to describe, and there were many issues which meant it was constantly being repaired (heat particularly and diffusion of light).

It was made of cardboard postal tube and tin cans and tape pretty much plus sanded pieces of hard plastic. I aimed it at the wall like a rifle, which meant the paper needed to be taped to the wall.
