I'm wondering if anyone has experience with pushing Fomapan 400? What was the approach and was it successful? I ask because I bought some in Thailand a while back (Tri-X was $6/roll, couldn't find HP5) having run out of my usual HP5+ and just started using it as I would the HP5; one stop underexposure (EI800) and vary processing accordingly. There has also been the occasional 1600 and beyond.
Fast-forward to now, and I find myself unwell (again, something about this part of the world) and with time to spare, so I put it to use researching what do with this different film.
Everything I've read says the Foma really isn't 400 at all, apparently even Foma's data shows that it isn't!! Further, it doesn't push well either according to most accounts I've read. Should've read up sooner!
:bang:
So, what I'm looking for is some advice/reassurance from people who have used this film and underexposed/pushed it. Time/temperature/agitation/developer? I imagine I'll probably need to be using something like Microphen or X-Tol with maybe a higher temperature or less agitation.
I don't really expect what I exposed beyond 1600 to be wet-printable, but would really like the 1600 to be and definitely the 800. The one thing giving me hope now is that I've also used a little APX400 in the past and thought it pushed ok (and I've seen some other's results on here too), despite it being described as a slower than box ISO film.
Show me the light, please!

Hi, sorry, didn't mean this to go in the scanning section. If it could be moved to the more general part that would be great.
Cheers.

Here are some times I found for this film (packaged as Arista.EDU Ultra) with HC-110 (B).
@ 800 - 9.5 minutes
@ 1600 - 14 minutes
I'll look for some examples - pretty sure there was a boost of contrast but otherwise decent.
Going off of memory I remembered the advice that for every one stop "push" start by adding 50% to the base development time. That started out OK, but with an active developer like HC-110 I backed off just a bit.
(6.5 @ EI400 * 1.5 = 9.75 @ EI800 :: 9.75 @ 800 * 1.5 = 14.6 @ 1600).
One of my favorite films - have fun experimenting.

According to the Forma fact sheet it can be over exposed by up to 1 stop and under exposed by 2 stops.

Fomapan 400 is usually less than 400 ISO of real sensitivity in developers like D76. Manufacturer's diagrams reflect that.
A few years ago, I used to push some in D76 stock to EI 800. The result was OK, but I'd rather not venture to 1600 with this film.

Thanks Gregg for your experience with this film, it would be great to see some examples.
Steve, I'd read that too and then just a couple days ago read a whole lot like varjag said (and worse).
I've decided I'm going to have to get some more of this film to experiment with before I start on my already exposed rolls. Hope it works out.

I just finished developing some foma 400 shot EI800 in Sprint (+3 chart letters), and it seems to have come out OK. I was going to push it to 1600, but wimped out at the last second. I won't win any image quality awards with it, but under the loupe things look like i'll be able to get a few prints out of it.
