Great image.... Traditional materials and gear and good technique can still get it done correctly! May I ask what you rate PanF+ at with Rodinal? I've got a large stash frozen and have been going to have at it a bit.
Great results. I recently used some Pan F Plus at 25 and found the results fairly low in contrast so suspect you made the right decision here with a 50 rating / development.
I always rate Pan F at 50 and soup in PyroCat-HD. Great film! BTW these images remind me of HiHoSilver's favorite subjects. Still wonder what happened to him.
