I request and require some input from the community on high speed films. My main film at this time is Agfapan 400, in both 35mm and 120 sizes. When my current supplies are exhaused, I will then be switching (back) to Ilford HP5 as my main film. I have next to zero experience with higher speed films. Yes, I know that I can "push" Agfa 400 or Ilford HP5 two or three stops, and have done so, with both films. What I am looking for is personal experience with the three current high speed films, Kodak TMAX 3200, Ilford Delta Pro 3200 and Fuji Neopan 1600. I currently use HC-110 and D-23 developers, and would like to stick with these two for the forseeable future. My main considerations are speed and sharpness; large grain is not a problem as far as I am concerned. I would value input from community members who have had experience with these films.
