120 Tri-x @ 1600 in HC-110

Postby Cschwa17 » Fri Jan 05, 2018 2:51 am

Im developing 120 tri-x shot @ 1600 with hc-110. I have a three reel plastic tank but im only using 2 rolls of 120. I have read all the sites like mass dev and have been all over google. Can someone please give me a standard dev time and dilution. I do not understand about hc110, do i take syrup and put it in water, then use that mixture with other water to create working solution? I could really use someone just spelling it out for me. Thank you in advance. Also is it ok to just use 1000ml of solution, which will cover the 2 rolls of 120, but wont fill the tank.

You have under-exposed your film. Nothing can be done.

this has been ornello's mantra for years, and fortunately, not everybody has bought into it. true, you may lose some "shadow detail" but so what. you probably didn't want to take a picture of shadows anyway. anyway, yes, the syrup is mixed with the final volume of water. for example, my current preferred method of using hc 110 is to mix 1 oz of syrup with 120 oz's of water to stand develop (another technique that makes ornello's hair stand on-end) for around an hour, no agitation after initial agitation of 30". have never tried this with film underexposed this much, but I have entertained the thought. I would test with a snipped-off portion of this film before committing the whole roll. with 120 this may be a bit awkward. try a sacrificial roll exposed about the same way, if pix on first roll are really important.
also, I tend to overfill by an ounce or two, no matter what developer. I am a little neurotic about premature developer exhaustion and full coverage of film. anyhow, this is only a suggestion. it's all fun.

Your film is two stops underexposed. Nothing can be done. If you had overexposed it by the same margin, there would be no problem, and no change to processing would be needed. B&W negative film has no underexposure latitude, but about five stops of overexposure latitude. If you make the best prints possible from a negative given 1/2 stop underexposure, and one given proper exposure, loss of shadow detail will already be evident. A print from a negative given one or two stops addition exposure will be basically identical to that made from a properly exposed negative.

Orny:
please explain what you mean, "nothing can be done". tri-x has been underexposed two stops for decades, with results that have satisfied the shooter. though the results may not be satisfactory by your standards, if they were so terrible to other people, who have continued to do it, what does that say about their standards?

Underexposure cannot be cured by increasing development. End of story.
