Help on development time on dated 320 TXP

[cdowell]

Just enough variables on this processing goal to send me to the group. I needed to test the zone focusing on a camera I took apart and put back together, so I'm not worried about getting great negatives that do anything more than show me if the focusing works as expected. I used a tripod and a tape measure, etc and kept notes.

But the light was going and I ended up exposing as follows.

1.) a roll of 320 TXP (tri-x 320) that expired in 2009, metered at 800 since that was the light I had.
2.) the only developer I have on hand is Ilfosol 3.

Anybody got a time recommendation on old 320 film exposed at 800 and developed with what I have on hand? I just want to make sure I get results I can see since I kept a lot of notes and would hate to trash the roll.

Thanks for any suggestions.

I have never pushed Tri-X so I can't help. 2009 is not that long ago for B&W film, though, so I would just do normal push processing for 800. Flickr usually has some examples.

I'm assuming the film was stored well.

I watched a guy who does Youtube videos check the focus on his folder using a cheap shoe mounted range finder and some material he made use of as a ground glass. Depending on what kind of camera you are talking about, you might want to try it out for checking focus. His channel is "Shoot Film Like a Boss."

Normal processing. Lets not over think this.

320 TXP is, of course, a somewhat unusual emulsion.
FWIW, Kodak recommended that you process normally for one stop under-exposure (EI of 640) and a 50% increase in time if you under-expose by two stops (EI of 1250) and develop in X-Tol.

Thanks, all, for these insights. I went about 40 percent over and seem to come out alright from what I can see.

+1. I'm still using Verichrome Pan which is about the same age as your TXP, I give it the same development as I did when it was fresh.
