help! forgot filter factor with tri x - which developer for full box speed?

[frotog]

shot 4x5 portraits with tri x and forgot to compensate for two thirds of a stop filter factor. i've effectively exposed my film at 320 asa. i'd initially intended to develop in pmk but did not even bother once i had realised my mistake. i've tried pyrocat but it's not sufficient for the shadows. the portraits were made in the shade with morning light being redirected with bounce panels. in other words the scenes display a large subject brightness range. which developers would you test for compensating effects (i need to compress) but maximum film speed?

X Tol or D 76 1+1 ...maybe Microphen

I'm confused.

Which Tri-X were you using - Tri-X 400 or Tri-X Professional (320 ISO)?

Did you meter at EI 400, EI 320 or ????

Champion promicrol develop for 9 minutes at 1/19 shold do the job, did it for me when I overexposed some HP5+ by a stop and got nice negatives,Richard

tri x 4x5... i think it's only available as 320 asa. right? x-tol is one of the developers i have in mind... how best to use it for broad sbr? greater dilution, less agitation, longer times? i'm also considering running some test negatives in rodinal, semi stand at one to fifty. not sure if i'll get the shadow detail of xtol though.

Unless it is really old film the Tri-X you are using is Tri-X Pan with an ISO of 320. So you exposed 320 film at about a third stop off which is well within the latitude of exposure of the film. Just process it. If you are nervous, process on sheet at a time until you are convinced that you can just go ahead and process it.

I agree. I think you need to sacrifice one sheet with your normal dev routine before you try anything else, maybe give it a nudge up on development time...EC

 

[frotog]

clearly. developed one sheet in divided pyrocat... shadows dumped. incident light readings in high contrast settings. portraits. i need a compensating developer that will give the most shadow detail possible but delivers good separation in highlights.

I don't know about sheets, but I expose rolls at 320 and develop in PMK, 10m @75f, the last five minutes with no agitation.

If you had a filter on and did not adjust for it, the film received 2/3 stop less exposure, not more.

Diafine?

I have a friend who makes photographs of shiny metal objects with beautiful, delicate, glowing highlight separation. He devs 4x5 Tri-x @320 ISO in Rodinal 1 + 200, agitate about 15 seconds to remove the bubbles and then stand for about an hour. It make nice negs but my own developer is Germain's Finegrain which does what I want. In comparison, using identical sheets, the Rodinal routine definitely lowers the contrast. I have only developed a few this way in the last weeks, being back on a Tri-x kick, and haven't printed them yet...EC

 

[frotog]

Thanks eclarke. I haven't tried rodinal stand at high dilutions with tri-x. It's definitely a combination I'll test. I'm concerned that it won't bring out as much detail in the shadows as I"d like. I've used rodinal stand with 3200 and fp4 with good results. I concluded that fp4 needs at least iso 80 for printable shadows.

Ummm, if you had a 2/3 stop filter on and made no compensation surely you are looking to 'push' 2/3 stop ?

So you effectively exposed the 320asa film with an EI of about 500 and want to get back some potentially-lost shadow detail - is that right ?
