Re: Fuji Acros experiences
I don't have the specifics here at the office, but dev times aren't terribly different. Very
different animals otherwise. ACROS is orthopan rather than panchromatic per se, so gives
a different look to foliage etc, and has much better recip characteristics with long exp.
It is finer grained, but I personally use it at the same speed as FP4.
Re: Fuji Acros experiences
I have not used it in sheet format, but love it in 120. As an aside macrodirect.de also have Acros and are EU based, I have not however used them myself and they are quite a bit more expensive. If you do get some from Japanexposures I would be interested in knowing how it works out, and if you end up getting charged VAT as that it always a killer.

Ouch! even with getting stung by the VAT man, Japanexposures looks marginally cheaper. Considering whacking a slightly larger order on credit then re-couping costs by auctioning off the extra film.

Drew, what do you mean orthopan? Looking at Fuji's spectral sensitivity graph for Acros shows a bit more sensitivity at the red end of the spectrum than their other B/W offerings. My understanding of "ortho" films was a lack of red sensitivity...what did I miss?
Re: Fuji Acros experiences
I've been using Acros for a decade. Fuji lists it as a panchromatic film and it acts like a panchromatic film.
Re: Fuji Acros experiences
Nope Kirk. Take a close look at the red end of the spectral sensitivity chart. Then take something like a hard 29 filter and see what happens - anything stronger than a 25 will
simply attenuate about a stop of the shadows, despite compensation. Or do the reverse
and take a green filter which would ordinarily naturalize the look of foliage in pan films -
they go way up in scale with ACROS. That's why I love the stuff in the mtns - the conifers
are more buoyant, the skies more subtle. The only other popular film with analogous characteristics is Efke 25, also orthopan (not ortho either).
Re: Fuji Acros experiences
I use a lot of Acros, and I think there's no better film in its speed class, and plenty that are worse. It looks fantastic developed in 510-Pyro or Obsidian Aqua. Lately I've been experimenting with sharp, medium and slow films, exposed in hard light with a soft lens, and developed in acutance developers, and I really like the look -- creamy, smooth, grainless, and with high definition.

Excuse the poor lighting -- I'm still learning.
Re: Fuji Acros experiences
Gosh Jay, at least on the screen that shot sure has that lovely "illuminated from within" look. An actual print must be wonderful. To do that with TMX back in the day, I had to add a light yellow-green filter, and it still wasn't as subtle. The effect is subtle, and hard to achieve with a typical pan film.
Re: Fuji Acros experiences
David - "orthopan" is simply a sub-category of panchromatic and might not appear as an official designation in marketing literature. It has less
red sensitivity and therefore slightly more green sensitivity than typcial pan films. The opposite would be "extended red" pan film like Tech Pan or
early TMax (not the current version). Even IR films are technically panchromatic. True otho films, on the other hand, are not supposed to see red light at all, or else are very insensitive to this. But some graphics
ortho films are basically blue-sensitive, with just a hint of green sensitivity.
With a film like ACROS, diagnostically working with sharp-cutting separation filters will quickly differentiate the orthopan nuance from typical pan taking films like FP4.
