Just to be clear…. I still stand by my original processing technique outlined here in FR years ago which does not use the pre wet and has slightly more agitation than the technique outlined above (metal reels and tanks only for the older process). If the film and agitation technique is perfect without a pre wet then go for it but I have found most modern films do benefit from the pre wet… the only downside is developer longevity and about 1/3 stop loss in speed.
Running a test with my new ORTHOTOPOSCOPE SS camera (6×12) and a non optimized pinhole of around F70 (optimized is around F130 for the 25mm focal length). I am looking at the following films with EI from approx 100-1600 all in developers I have found that works best for maximum compensation and best overall tonality with each specific film. Reciprocity corrections were kept to just a gerous doubling to time— with this type of camera and work I like to keep it simple if possible. Exposures ranged from 1 second to 30 seconds all handheld as that is my standard way of shooting with a pinhole system.
400TX • Diafine
400Tmax • 510 Pyro
Delta 3200 • 510 Pyro
Fuji 400CN • C41
Portra 400 • C41
CineStill 800T • C41
All test results will be converted to B&W as that is my current need with these materials.
UPDATE: So I’ve looked at the film and I am very drawn to the Porta 400 and VERY drawn to the Cinestill 800T when both are converted to B&W. The regular B&W film was amazing but due to the pinhole capture I had a lot more range of possibilities in the conversion process that really helped to bring out crazy tonal separation in the two color negative materials.
So I am heading back to Paris tomorrow provided I can make it to Boston to get my flight!
On my last trip to Paris 5 weeks ago I shot with the Leica Monochrome exclusively…. on this trip it will be my Leica M4 film cameras exclusively! Hint… my next big article here on FR.
I have also been testing a lot of film and developer combinations the last 5 weeks… a lot! I really like the Bergger BRF 400+ in Caffenol CL and Caffenol CH with EI in CL out to 3200+. Rodinal provides a very crisp negative and Xtol is another good choice at 1:1. Another film I have been testing a lot is Delta 3200 processed in PMK double strength… nice range of tones and usable out to 6400 and perhaps 12,800 with proper shadow metering. Today I am running a test looking at the Delta 3200 in PMK with 1.5 strength as at double the highlights get a bit hot at lower EI’s… I want it all- 400-6400!!!!!! Stay tuned!
Oh and the Bergger BRF400+ in PMK is around 200-400 with a beautiful tonal quality. I have heard many people compare the Bergger to Tri-X… Yes, but only if you are talking Tri-X from the 1970’s and even then it is more like XX than TX. It is very low contrast film which is a good thing for scanning and has a softer rendering then most modern films… perfect for a classic look. In Diafine it is nice but the grain needs a bit of a kick in PS with some structure and a “S” curve to add depth- in Diafine a usable EI of 1600 is not a problem.
