I decided to take a close-up picture of a rose. I wanted to challenge myself, so I took the picture on my Mamiya RB67, which has no metering, no electronics, or in fact anything at all – apart from a gurt massive piece of film.
The RB67 has built-in bellows so any lens becomes a macro lens. I experimented with a 180mm lens and a 50mm lens (although remember this is medium format – those lenses have approximately the same field of view as a 90mm and 25mm lens on a full-frame DSLR).

I’m pleased with the result, although I think the rose is overexposed by about one stop. But this is the fun of shooting film!
Photo taken using a Mamiya RB67 with Mamiya Sekor C 50mm f/4.5 lens on Kodak Ektar 100 film. Two strobes, one pointing at the rose from camera right, the other camera left bounced off the ceiling. Artex makes a good diffuse reflector, it seems, even if it is hideous.
