I love it when things just work.

From the Jim Thorpe Burlesque Festival: the negative comes from 4 rolls of HP5+, under-exposed at least 3 stops at the Mamiya’s metered 3200 (which I find to already under-expose a touch). I optimistically developed the first roll at 6400 in Microphen (finding it very thin), and then the other 3 rolls at an approximate ISO 35000 – 40 minutes, based on the response curve I’ve calculated from repeated development work with this film and developer. All of this in a hotel bathroom while traveling for a conference, so I re-used the single liter of Microphen for all four rolls. This came from the fourth roll, which developed for a whopping 56 minutes.

This is a kallitype print of a digitally enlarged negative of that shot, using curves I generated from repeated test runs. I’m quite happy with the result; it’s actually slightly darker “chocolate brown” than this scan came out.

I’m expecting some gold chloride and palladium salts in the next week at which point the toned kallitypes will begin!
