I experimented with a '0-budget' enlarger/projector - used a 55mm lens and an extension tube, a cardboard box, a worklight with a flourescent lamp on it, and a light-tight changing bag. It sucks.
But I got results (yeah, they suck too, as does the picture of them since I broke my scanner)


Now I need a real enlarger. And a room that's actually light tight would help. It's not too bad using tin casserole dishes for chemical trays though.
