Tested Tri-X 4x5 (again) and developed it in X-TOL 1+1 (mixed with distilled water) in Jobo ATL-1500. The densitometer readings confirm my E.I. at 800!
How is this possible? I am somewhat suspicious. Has anyone encountered similar results?
I did two batches of six negatives: one developed in the Jobo and the other by inversion - same results. I shot an urban landscape at 320 and 800; the first one is super dense and the second looks normal. The lens' shutter is accurate (1/60th).
This is the second time doing a speed test using Tri-X with X-TOL 1+1. The first time, I was just as incredulous at the results and sent the second batch to R.Ritter who confirmed the negative rated at 800 as the proper Zone I exposure.
Since that time, I have been shooting E6 Fuji Neopan Acros 100 QL's in B&W, so I just set aside those results.
Previously, I was using the old Tri-X with HC110 and and was rating it at 250.
I am setting aside these results again. I am leaving on a trip tomorrow and will be shooting some of my Polaroid 55 stash and Fuji Neopan Acros 100 QL. (The Neopan tested at full box speed with X-TOL).
