Many moons ago, when I did my own B&W processing and printing, I used this film as the ultimate for fine-grain. It was, from memory ISO25 and had to be processed in in Tetenal Neofin-Doku and printed onto quite contrast paper to get a good result.
Although I don't currently have access to a darkroom, I was wondering if this film (or a replacement) is still available and whether any of the pro labs in London will process / print from it.
Hello Paul,
I have used Kodak Technical Pan as well in the past. In combination with Neofin Doku, too.
Now I am using Rollei ATP with Rollei ATP DC developer as a replacement. Concerning resolution, sharpness and fine grain both films are very similar. You get outstanding results. The tonality is a bit different, but that's a matter of taste (I like ATP more).
With ATP, developed in ATP DC developer, you can get a bit more speed, about ISO 40/17°.
We have used this film in a great film test (resolution comparison film and digital sensors).
With the new Rollei ATP, developed in the dedicated ATP DC developer we achieved so far a system resolution of 140 Lp/mm (50mm prime lens+film). The 140 Lp/mm pattern is so clear that this film is not at its resolution limit, further tests for higher resolution are necessary. This film has such extremely high resolution, sharpness and fine grain that you can get results with 35mm film which are on a similar level with medium format. And now this film is obtainable as 120 film as well.
I recommend to develop this film by yourself. Printing of negatives in a good pro lab is not a problem at all. You can print this film like any other BW film.
Best regards,
Henning
