  Q. Tri-x 320

Asked by Andrew  Todd    (K=50) on 1/9/2006 
I just did a personal ISO test on the new TRi-x 320 TXP 4x5 film from kodak and found that it actually exposes at around iso 160. Has anyone else done this and had similar or different results? My densitometer is old and used so results are debatable. Anyones personal experience with this would be much apprciated. thanks

Andrew,

I use the 120 version. My method of determining my meter setting could not be called an ISO test, but it's based on toe speed and then checked in practical use. I find that 250 to 320 works with Xtol and 200 works with W2D2+. What test method are you using and what developer?

Best,
Helen

im using HC 110 (dilution B) and to determine the iso I make a zone 1 eposure using the films recommended ISO and then make 3 more exposures: one 1/2 stop under and 2, one 1/2 over and one a full stop over. Then based on densitometry readings i determine which is actually a zone 1 density and adjust my iso accordingly.

Andrew,

I think that the best thing to do is to try metering at 160 and see how you like the results. 160 doesn't sound bad for the method you have used.

Best,
Helen
