There you are , The GreatGasman, there is a Kodak time which I'd go with. If a maker of both the film and the developer has taken the time to do this then the odd favour this being the right time
The massive dev chart is very useful, but also very frustrating sometimes. There is no sprint standard time listed on the site, but sprint has a time listed on its data sheet.
I assumed that the OP was developing old roll film. As Kodak doesn't make T-Max 320 in roll film sizes any more, the current KodakTri-X datasheet doesn't list a time for roll film development using small tanks and inversion agitation.
Thank you very much.
and as I said- the massive dev chart has no such indications which are which.
It's a 220 roll. I developed a roll in d76 1:1 earlier this year, but I've since been converted to hc110. I also do have a few more rolls if this happens to not work out.
I don't trust (as in lack confidence in) the MDC, and will only refer to it when it is the only source of information for some odd combination of developer and film. As an example, I have some very old Neopan 1600 that I would like to develop in replenished X-Tol.
Pretty much my only access to film dev times- outside of photrio, and I don't want to make one of these posts unless I absolutely need to.
Here is a link to the 2007 Tri-X datasheet which does deal with roll film Tri-X 320. and provides the same time: https://125px.com/docs/film/kodak/f4017-400TX-2007.pdf
Here's a sample from the d76 roll I shot earlier this year- no idea what the age was, wasn't even wrapped, shot it at iso 80 and used whatever the massive dev chart said for d76 1:1, and the results weren't that bad
Yea, I'll remember this. I just assumed everyone would just go for the standard 68ºf and agitation every 30 seconds. Though I did provide that link for reference.Here is a link to the 2007 Tri-X datasheet which does deal with roll film Tri-X 320. and provides the same time: https://125px.com/docs/film/kodak/f4017-400TX-2007.pdf
Speaking generally to anyone reading this, it helps to know which format of film (particularly sheet vs. roll), what mode of development and agitation you intend to use, and what your target working temperature is when you ask about development times.
Hope all this helps.
Wish I had some 220 Tri-X
Me neither. Even if I have an odd film - developer combination where there's no official data, I'll just do a clip test until the film becomes reasonably dark and count the time it took. I'll also fix it and eyeball the density against a lamp. If it looks good enough, I'll commit some film to it. I sometimes bracket some shots of a gray card, which also enable me to plot a characteristic curve. It might not be perfectly accurate, but it's useful nonetheless.
The next one (whenever that will be), may end up being the 5.5 minute dev time. And though that d76 roll came from a different lot- that one turned out quite nice, for an expired bw film anyway.
The 1999 Kodak recommendations for the old version of Tri-X 320 specified 5.5 minutes, not 7 minutes (20C and Kodak agitation).
Nope, everything's alright, But I am going to try a longer dev time whenever I get to the next roll.
Out of curiosity, how exactly is the film "badged"? I'm wondering if the film is old enough that the 1999 datasheet should be used (5.5 minutes) rather than the 2007 datasheet (4.75 minutes).
I have the box, but the expiration was torn off, but I remember the seller indicated the film probably expired in the late 80s to early 90s. I don't have the box with me right now, so I also can't reference it.
Thank you again- this really helps. I also didn't mention I previously developed a roll from this lot in Sprint standard sometime early 2019 and got a similar result. But yea, it's good to know the difference.
