I've heard some nice things about Tri-X 320 in 4x5 size and am thinking of trying it out. Just looking for opinions between the two from those who have used them.
No one's used them both, because they don't make the 400 in large format sizes. 35mm and 120 rollfilms only. I have used the 320 in 4x5, developed in Rodinal, and It gave beautiful tonality. I need to get a scanner that can take 4x5 so I can put them online. I only shot 4x5 for a short time before realizing that I am not healthy enough to carry that much gear. I still have the camera, I should sell it. Its not been used in a decade!
Kodak's marketing of Tri-X was and is weird. The 320 and 400 versions of Tri-X are actually quite different films, aside from the speed difference. The 400 was made in 35 and 120 and the 320 was made in 120 and large format sizes (4x5, 5x7, 8x10). So, 120 users could choose, both films were made in that size, but 35mm users got the 400 only and large format users got the 320.
I'm almost positive that both types are still available in 4x5. Assuming it's the same emulsion as the 120 version, I found the 320 version to be harder to meter outside of a studio, and prefer the 400 ISO version. When I shot 4x5 I used "classic Tri-X" in 400 speed and just loved it. What a great film.
It seems that the ISO320 needed to be more precisely metered and exposed and that the 400 was more forgiving, i wonder if anyone knows the emulsion types or numbers for these two films, as they have to be different from each other.
