So you are preflashing the XRAY film with a Zone II value? I imagine that would build up the toe.
OK. I know Robert. Thanks.Quote:

I have only tested it with this film, maybe the other xray films are working different.
In the early 1990th I used lith films with uncoated fast lenses like the Xenar 3.5/240mm and it were possible to get a grey scale with this extrem high contrast films.
I find it is much easier with a xray film.
It were bad weather work, we have had rain for over two weeks, it were ok, we need the water and I used the time for lens and film testing.Quote:

I am an experienced photographer in many ways, and won't say much more than that. I am however, new to shooting X-ray film in a camera. I have a box of the Fuji Green in 8x10 coming this week. I will be playing with it alongside paper negatives which I have been shooting since the 90's.
I am very comfortable mixing developers from scratch and doing my own testing. My densitometer is stuck in storage in Utah right now, so I won't be able to plot the x-ray film and compare developers. My end goals are to make both GSP's as well as pt/pd contact prints. I have a 'Dorff 8x10 and a Korona 12x20 as my main landscape cameras.
So, the question is, has anyone done any curve testing of the green and/or blue film with the various developers (and apparently yellow is the filter of choice with the green film)?
If this is ground which is well trodden, I apologize. I have found many threads where each practitioner has their developer/filtration/developing method of choice, and am having a difficult time deciding which developer to use. I will tray develop them one sheet at a time.
Thanks again and bravo to the brave ones who have stuck with this media for so long.
