Tri-X HC-110 Dil-D dev times

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

Hi everybody. I decided to play around with the good old HC-110 to see if I can squeeze some more out of it. Does anyone have the times for 35mm Tri-X ISO 400 in HC-110 dil.D (ie 1:39 from concentrate or 1:9 from stock) for 200C and 5/30s agitation.I believe it should be around 8.5-9 min. I hope to improve the sharpness a little bit and don't care so much about the eventual grain increase. Thanx. Evgeni.

tho i do not use dil d i believe the time should be around 9 min @ 68f and would recommend as a starting point to anyone who asks, though i doubt i would suggest rating the tx at 400. i would start around 320. If that didn't hold enough for my taste, i would back off to 250. let me know how you make out with the density/contrast/grain/tones/etc. Sean

1+39 is the only dilution I use for HC110, because stonger dilutions cause burn-out in the highlights (in my system). I always develop Tri-X exposed at 400 for 6 minutes at 20 degrees C; sometimes half a degree more. It's for a condensor in a Beseler (which is not a very contrasty condensor). I agitate the first 30 seconds and then 5/30; no pre-soak with 35mm. Beautiful results, always content. I print on grade 2, mostly to finish with Selenium. This procedure is especially suited for long brightness ranges of say 8 stops, but with VC-paper I can manage lower contrast situations with this too.

Lot- Last night I developed TriX (shot at 400) in dilution B (1:7) for 8 minutes (N+1) at 20 C and was disappointed to see extremely dense negatives- i.e. highlights are almost certainly burnt out. I'll try your formula and make personal adjustments as needed. I just switched from TMax developer to HC110. We'll see how it goes.

Have you ever exposed Tri-X at 800 and developed in HC110 dilution D? If so, what times do you recommend?

About 7 minutes, but I've got bad experiences with it. It's better to use Tri-X's latitude for 1 stop underexposure and just develop for 400 ASA; print one grade harder or split-contrast printing will help you out better than too dense negatives.
