Ilford HP-5... 6x7 medium format exposed at EI 100, developed in ID-11.
HP-5 inadvertently exposed at EI 100 instead of the usual EI 400. I cut down the developing time from the normal 20 minutes to 17 minutes and the temperature from 68 degrees to 62 degrees. Overexposure and underdeveloping results in reduced contrast, which in scenes such as this is a good thing.
