My brother loaned me his old SLR camera, a Yashica FX-3 Super 2000. He bought it in 1987 for university. It was $500 at the time. It's totally manual -- the batteries are needed only for the light-meter.
All I need now is a fast lens and some high-ISO film, and my dreams of low-light photography will be realized!
Processing: edge detection, thresholding, inversion, and a slight blurring.
