I have noticed that the fomapan 100 appears to have quite bad shadow detail ... and not just that but the shadows appear quite grainy as well (Processed in xtol). As a possible solution, I though I might try shooting the Foma at iso 50 and seeing whether that improves the shadow detail.. would do you thing of this strategy?

I did extensive tests on Arista Edu Ultra 100 sheet film, which is basically rebranded Foma. I preferred exposing at EI 50, then dev'ing at the standard EI/ISO 100 settings. There was a great deal more shadow detail, and the highlights were still well-managed (though you have to be more careful, obviously).

I do exactly as BDT mentions with the same results.

Honestly I shoot more for 25 when I use this film. Part of that might be me using D23 which sacrifices a bit of speed compared to MQ developers, though.

In the Landscape picture thread on page 234 there are a couple of shots developed in Rodinal. When I saw these I thought I aught to check the film out.

I rate it at 50 iso and rotary process it in Pyrocat HD for 9:21. If processing in a small tank I develop it for 11 minutes. It gives plenty of shadow detail and manageable highlights with this combo. Its a shame that the quality is inconsistent.

These are three 8x10 pictures on Fomapan 100 (shot ISO 100), developed in Rodinal. I think they are fine:

Because I'd heard reports of it's high contrast etc I did a series of tests before using Fomapan 100.

My experience mirrors others it builds up contrast very quickly so development need to be cut back and exposure increase, so like Scotty I use it at 50 EI and 11 minutes in Pyrocat HD 1+1_100 @ 20C. That tames the film nicely and I get excellent shadow detail.

I tried Fomapan 100 for the first time and shot at EI50 and still found the negs a little short on shadow detail. I'll try some at EI32 the next time I go out. I developed at 1:1:100 in Pyrocat HD rotary @ 18C for 14 minutes. The longer development time is for building the density needed for Pd/Pt and other alt process printing.

My net .10 density put it right at 100. I was surprised, but it works!!

I shoot it at 80 asa with rodinal 1:50 8min = N with good results in a roller tank. About 10.5 by hand

I shoot it at ISO 50 and develop in divided D23 using a Nitrogen burst developing tank. I then scan the negative and with minor adjustments to the curve it gives me an excellent ink jet print.

1/2 box speed and shortened development time seems to be the norm for Foma/Arista sheet film. Get the exposure & time right and the film works well. My current choice is the Foma/Arista 200 @ 100 in Xtol 1:3 for 10 minutes or less and continuous agitation. I'm about to use the last of my old formula from a 100 sheet box. I'll be trying the new version of the film and 50 sheet packaging. I sure wish they still sold 100 sheet boxes.

What quality issues are you facing?
