My recent Ilford FP4+ development times article seemed to cause quite a buzz. Mostly around the topic of “why would you even try to shoot this film at EI 6400?!”
I’m not really one for standing still and with that in mind, I’ve decided to publish my personal development times for Kodak’s Tri-X 400 from EI 200 all the way up to EI 25600.
As with the times published in the Ilford FP4+ article, the tables below show both real world tested and untested (extrapolated) development times for this film.
The times listed below may not work for everyone (differences in water quality/hardness/softness, agitation schemes, etc.), however I’ve yet to hear back that any of them were anything other than a success – here’s keeping fingers crossed.
The times below with ISO400 as the base speed (N). All other times vary from that as N+/- in full or fractions of stops
Ready? Here we go.
