Thinking about Getting Some Fujifilm Neopan 100 Acros B&W 35mm

I'd like to try out some 35mm Acros film, but I read it's an orthopanchromatic film. I'm wondering, what differences there are compared to, say Tri-X? Any photos?

 

Thanks!

My favorite B&W film. Best processed with Perceptol. It is nothing like Tri-X. It is a modern emulsion similar to T-Max and Delta, so if you're looking for grain then Acros is not for you.

I really like Acros. It's different than Tri-X, smoother and a bit sharper to my eye (micro contrast.) That of course also depends on your developer. My developer of choice is Diafine, which makes even Acros have a bit of grain.

 

I especially like how Acros doesn't crush the blacks or highlights. It has a long straight characteristic curve without much shoulder, so you get lots of detail throughout the exposure range. Some may find that it looks "flat" because of this, but it's easy to get more contrast if you need it, and harder to get rid of contrast.

I see where Perceptol is toxic and may cause organ damage with long exposure. Also, it is very toxic to aquatic life, so how could I pour it down the drain to dispose of it?

Dilution is the solution to pollution. It's not so toxic that it is a hazard when properly used.

It seems that fujifilm.com only has color negative and reversal films, though is in English.

 

fujifilmusa.com has Neopan 100:

It is usually stated that the visual spectrum is 700nm to 400nm, though both ends are pretty much on the tails.

 

You can see here:

that TMax 100 goes just a little past 650nm, which I believe is usual for panchromatic films.

 

Neopan goes to maybe only 630nm, so just a little less. It also has a dip around 500nm.

To be clear, Neopan and Neopan Acros are two different films.

Thanks for that info!

Fuji does not make that easy to figure out.

says "Neopan 100 Acros"

 

I didn't figure out the other Neopans.

As far as I can tell, there is now only Neopan 100 Acros.

 

There is a data sheet for Neopan 400: http://www.fujifilmusa.com/shared/bin/Neopan400.pdf

 

and also one for 1600, but they might not be in production.

 

I don't see a 100 that isn't Acros.

That's correct. The original Neopans 100, 400 and 1600 were traditional emulsions similar to Plus-X, Tri-X, FP4, etc. and have all been discontinued. Only Neopan Acros 100 remains in 135, 120 and 4x5.

The fujifulmusa.com site still has data sheets for 400 and 1600, but only Acros for 100.

 

Also, the cut off for the red end of the sensitivity seems pretty close too 630nm, though 400 and 1600 are called panchromatic.

It seems that all the Fuji black and white films are "professional", and so not on the fujifilm.com site.

I used to use the Acros 100 but when its availability in 100' bulk ceased I lost interest. For a time it was even available as Legacy Pro 100 through Freestyle.

This one - Rocks and Water is Acros (in 120). Since it's rocks and water, it's tough to see how it behaves with trees, etc.. but the upper rocks did have a greenish hue if that helps at all. It's the only one in my flickr stream that's Acros, I think.

 

The main reason I like it is because you can stick with the metered shutter speed up to about 2 minutes. Though I don't do as many long exposures as I wish I did. I really want to do some night shooting, but never have time.

The long exposure capability (minimal reciprocity failure) of Acros 100 might very well be the best available. The box speed does not necessarily hold true for long exposures on many films. In the original TMAX 100 and 400 films, I think the 100 actually responded as a faster film past a certain amount of time. But back to Acros 100: I would probably shoot the occasional roll even in single roll price just for its superior reciprocity characteristics.
