due to a significant decrease in sales volumes, kodak is retiring its tri-x pro 320 b/w film in medium format [120/220]:
KODAK PROFESSIONAL TRI-X 320 Film / 320TXP / 120 pro-pack 5 rolls / CAT 8188914
KODAK PROFESSIONAL TRI-X 320 Film / 320TXP / 220 pro-pack 5 rolls / CAT 8286825

tri-x was released in 35mm and 120 formats in 1954. this is the film i learned to shoot large format and used primarily [along with tri-x 400] throughout elementary, high school, college, and even in recent projects.
tri-x pro 320′s characteristic curve, with an upward sweep, has always had a longer midrange — thus expanding highlights and compressing shadows — widely popular in reproduction, magazine, and catalog photography.   kodak had designed the film’s curve for controlled, studio lighting conditions.

tri-x 320 pro is [was] also a venerable choice for super 8 cine film. and you can soup the super 8 film yourself!

for silver prints with tri-x pro, i always favor compensating development, utilizing a cold [diffusion] head, and letting the highlights fall where they may, exposing for the shadows [rating the film @ iso200 in extreme daylight / iso320 in even/controlled light, and never afraid to push to iso800 or iso1600 in certain situations].

hopefully kodak will stop discontinuing films that have been and still are staples in a photographer’s bag and an artist’s workflow. it couldn’t hurt to keep stock and volume at the pace of supply and demand, however it fluctuates.  or i guess it could.
a dark day for film.
