I have been experimenting with FP4+ in PMK. I am using trays and developing 10 min @ 70 degrees F.
The results have been interesting - I like the tonality. The mid- and high tones look fine, but shadows were thin. I have progressively reduced my E.I. and currently have been using E.I. 50, but the shadows are still a bit thin. I could keep increasing exposure and cut the development some, but it seems that having to shoot an ISO 125 film at E.I. 25 (which is where I think I would go next) seems like a high price to pay for greater sharpness and better highlight separation.
My approach is subjective -- I have a B&W densitometer, but I'm more interested in what happens with actual pictures of actual subjects.
Does anyone have specific experience with this combination? I'd be interested in what you have found to be a proper speed.
Thanks
