I never had issues with Fomopan 100. This was rated at 400 i.e. pushed 2 stops, using DF96 Monobath.

Looks good. I don't understand when people say some film is problematic without talking about the developer used. BW film and developer go hand-in-hand to produce the final results. A film like 320TXP developed in Rodinal, for example, is much different film than when developed in D-76.

I agree 100%.

I’ve used commercial labs for probably 95% of my black and white film work in the past decade or so, so I’m constrained by their results.

Neopan? Beautiful ( haven’t tried the new batch). Tri-x? Awesome. TMax? great.

HP5? Contrasty, grainy mess. Fomapan? Worse than the HP5, despite being two stops slower...

So until I work out a developing scheme at home, I’m stuck... back in the day, it was TMax in TMax with multi contrast paper... what couldn’t I do?

We were going to have a local rental darkroom open up before COVID messed up everything... sigh...

I'm amazed I got any frames at all off this roll. Not only did I open the back on the film, I later went and did it a second time.

Due to Covid I started developing my own using Cinestill DF96 Monobath.
One liquid - reusable 16+ times - does it all.
Super easy with excellent results.

I load the dev tank in a closet at night. Then do the rest in my bathroom which entails in pouring in the DF96, then pouring it out (and back into the bottle from whence it came), washing/fixing the film with tap water, then hanging to dry.

The B&W images I've posted on this site are all processed with it.

Mamiya M645 1000s, 80mm f2.8 C, Fomapan 120 100, Ilfotec LC29, Epson V550. Cheap film with good results. I suspect larger formats are more forgiving of this film.

I shot some Fomapan 100 in 35mm about 8 years ago, and it looked like overdeveloped Tri-X.
I wasn’t a fan...

But a bigger negative would have helped a lot...

I've shot Fomapan 100 and found it to produce very nice images with good tones and contrast. The first problem with Foma films is that they are generally rated around 2/3 of a stop faster than they really are, so the 100 is closer to 64 or maybe 80. The second problem is that the negatives are very, very curly, making them difficult to scan and impacting on the sharpness.

I haven't tried Foma but is the film base like RR 80S and RPX 25 which also is really curly?

I find it is not easy to consistently develop my film to 1/3-stop of precision. So I'm curious how people ascertain 1/3 stop film speed ratings when they don't measure the density of their BW negatives. Printing on a fixed grade 2 or 3 paper is one feedback method but most people are scanning these days I think.

I don't have them handy at the moment, but with Foma it's generally been via the response curves in their published spec sheets.

Okay, you mean the published characteristic curve of the film for a specific developer?

I use the zone system's method to find the speed of my exposure/developer/agitation profile/film combo. In a nutshell, you place a grey card at zone 1, bracket your ISO, develop and find the negative that measures closest to 0.10 density above the base + fog density. If it is 1/3 stop off box speed, I don't even bother and call it box speed. I'd need to do the test multiple times and find the average really.

The leaf shutter lenses I own have rather large shutter speed variations in some of their shutter speeds. So getting down to 1/3 stop accuracy without performing a speed test on each lens and shutter speed I have is way more work than I want to do. I have a local repair shop that gets a lot of my business. He performs a shutter speed test on my leaf shutter lenses when I send them in for a CLA and, man, some speeds are off by a lot.

Good deal. What densitometer do you have?

RR 80s lays flat for 35mm. I have some in 120 that I need to shoot. Thanks for the head's up.

PF member Kris posted a picture back in Sept of the curl in his roll of RPX 25 in 120 roll. The curl on my RPX 25 is like that too but I have noticed after a year or so stored in archive sleeves it is a little more manageable. If you can overcome the curl, the film does produce a unique look with metallic things I think.

I don't have one. And, before you ask, I have never measured Foma & therefore can't saying about the accuracy of the published curves.

That's very interesting (and I guess makes Tuco's point). I also rely on commercial labs, and in my experience Tri-X and HP5+ have similar grain, but both Tri-X and Tmax have FAR more contrast than HP5+, which tends towards a million shades of grey without the use of colour filters.
