While I was at the Quincy Mine near Houghton a few weeks ago, I shot one roll of Kodalith (ISO 12) film -- and knew that I would get contrasty images, as it isn't normally used as a pictorial film. I developed under red safelight by inspection in Dektol (1:8) for about 3.5 minutes. I really like my results. The raking light at the end of the day really is what made the shots stand out. Scanned from the negative.
Both good photos. I went to Michigan Tech 1956-60, and have hundreds of negatives of the mining communities as they were then. Sadly, so much is gone. I'm glad people are still photographing the area so we remember something about it.
