I have a client who is looking to do a project possibly using Pan F and Pyrocat HD. Other Pyro developers would be acceptable as well for him. I'd like to advise him with a this vs that opinion, but even having used this combo in the past, I never had time to make any comparisons except that the Pan F negs looked great and will probably print so...if I ever get 'round to them. So I'd be interested in hearing from anyone who's used this film/developer combo and their subjective opinions such as better/worse shadow detail, etc. Feel free to mention any times/dilutions if you like. My assumption, at this point, is that the Pan F negs will has much finer grain and from what I've read, an EI of 25-32. My client's other film of choice is TMX and previous results using Pyrocat HD prompted him to call me from Paris to to laud it's qualities and sharpness. I imagine he may use both TMX and Pan F depending on the light. He'll be shooting 120 and 35mm for this project. Thanks for any opinions! Eric
