It can be pushed to ISO 25000. My camera only goes up to 6400...
... how little actual difference there was between TMAX 400 and TMAX 3200. It seemed to the author that the emulsions ... behaved essentially the same way at speeds lower than 6400.
It has been a long time but I vaguely remember reading an article in one of the popular photo magazines, back in the day, about how little actual difference there was between TMAX 400 and TMAX 3200. It seemed to the author that the emulsions—when processed with TMAX Developer—behaved essentially the same way at speeds lower than 6400 and there were only very subtle differences above 6400.Sorry not to be able to cite the source. I think the journal was Modern Photography and the article came out when TMAX 3200 film was fairly new.

I think the journal was Modern Photography and the article came out when TMAX 3200 film was fairly new.I've always suspected (with absolutely no evidence to support it) that all the 3200ISO films (Kodak & Ilford) are actually just the 400 films with a really long toe. I seem to remember shooting Delta 3200 @400 and it coming out very much like Delta 400, but I may just have dreamed that
Mike Johnston of The Online Photographer posted a history and usage summary for this film. It's an interesting read from someone who was apparently a beta tester for the emulsion when it was first coming to market. See https://tinyurl.com/y9dfrc92
I would disagre completely when he says dont shoot it at ei 3200. Pure nonsense. I have processed probably a good 200 to 250 rolls lf this...at both 3200 and 6400 iso. The results are good...if you appreciate grain.
btw, anyone shot the old Royal-X pan? Seems like a fun film_MG_0140 by Clay Williams, on FlickrISO 1250.another box photo from a later(?) iteration https://www.flickr.com/photos/48999929@N03/20181829189/
