I have been trying to determine which Ilford powder developer, ID-11 or Perceptol, will give me best sharpness, resolution, detail (or what have you) with 100 Delta Professional for an upcoming project.
After pouring over the Ilford literature, I find that the film poop sheet says that ID-11 @ 1:3 delivers “maximum” and “excellent” sharpness. Perceptol shows only “good” sharpness but “finest grain”.
Their Perceptol literature, on the other hand, states that, “It has been specially formulated...to exploit the superb grain structure of 100 Delta...therefore ideal when texture and definition are critical - negatives...are capable of producing sharper and better quality enlargements than those using a standard fine grain developer.”
It is beginning to sound as though each is definitely better than the other?
The only difference I can find is that ID-11 may yield more film speed and works with virtually all films. Perceptol may produce a decrease in film speed and is not recommended for their Ortho film.
I further suspect that the grain and inherent sharpness of 100 Delta is such that almost any soup will produce excellent results. And that I am really going to have to go out of my way to screw things up with this film.
Advice from my learned colleagues who have experienced these developers would save these old knees many hours at the lab sink.
