Film 26: Ilford FP4 and Caffenol

Last week at the Outer Circle Rd Industrial Estate in Lincoln, I loaded a roll of Ilford FP4 into the Konica C35v, which I finished yesterday in Sudbrooke (TF045763).

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 ⅔ stop too high. This was easily corrected using the meter adjustment.

Caffenol is a homemade developer, usually made from instant 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 3×500mg of ascorbic acid tablets before topping it up to 300ml with water. I then added 3 tsp of table salt as a reducing agent (to reduce background fog). After brewing for a couple of minutes, I poured it in and developed for 6:48 minutes at 27°.They were later scanned using a Plustek OpticFilm 7400 at 3600 dpi. Photoshop work was minimal, consisting of spot removal and curves.
