After finishing the gigabitfilm (see post on my website) during the 10K last Sunday, l loaded a roll of Ilford FP4 into the Konica C35v.
The Konica C35v is a zone focus 35mm viewfinder camera, though it looks similar to a rangefinder. It is fully automatic and features a 38mm f/2.8 lens. This camera, manufactured in 1974 should use mercury 1.35v cell batteries. With a modern 1.5v battery of equivalent size, the meter is two thirds of a stop too high. This was easily corrected using the meter adjustment.
As it was only a 12exp roll, I had intentions not to waste ID11, but try Caffenol for the first time.
Caffenol is a homemade developer, usually made from Coffee, washing soda and vitamin C. There are many different variations, some to individual films. For this film, I used 4 tsp of coffee, 2.5 tsp of washing soda and 1g of ascorbic acid powder before topping it up to 300ml with water.
After brewing for two minutes, I poured it in and developed for 4:11 minutes at 33°. They were then scanned using a Plustek OpticFilm 7400.
