Caffenol Concoction Test

All film was exposed at 100 ISO and developed in Labeauratoire's Caffenol Concoction for 15 minutes at room temperature.

Caffenol Concoction is a film developer made from household ingredients, so the decision to use the blanket recommended starting point of 15 minutes for all films and to dispense with adjusting the temperature of the developer (it was probably about 22°C/72°F) was made in the spirit of this "home brew" product.

Notes:

*While the results were all printable, the development time was clearly far too long for Ultrafine Extreme 100 resulting in too much density in the highlights. The results with this film are not useful for comparison except in grain structure. We would recommend a starting point development time of 10 minutes for Ultrafine Extreme 100 to produce the type of good results we got with the other films.
