I ran my first test roll through a new-to-me Mamiya 645 yesterday, and stand-developed it (also a first for me).
Unfortunately, I loaded the film backwards! Never seen such a clear sheet of film! That backing paper sure does its job!
The film was Neopan Acros 100. I had been developing a lot of Ilford, and I usually don’t do a presoak. Not knowing that Acros has such a thick anti-halation layer, I was not planning to presoak, but at the last minute decided to do it. I only gave it 30 seconds, but the water came out dirty blue, and I thought, “Uh-oh, that looks bad.” So I quick-rinsed it one more time and went on with the show. (HC-110 G, which is 1:119, for an hour, with only thirty seconds of agitation at the start.)
I am here to tell you that the clear film that emerged also still has a slight blue haze throughout.
Lessons: 1) Presoak your Acros 5 minutes. 2) A Mamiya 645 film holder has to have emulsion-side out when it goes into the camera (Duh!).
