Tri X - HC110 dilution G

[steve barry]

I have been using HC-110 dilution G for a few years, on both both acros 100 film and Arista 100 and getting results I am very very happy with in all formats 4x5, 8x10, 120 and 35mm.

Room temp chemicals (72-75 deg), 1:119, 60 seconds gentle agitation and then 45-60 minutes untouched.

It has been a while since I shot any high speed film, but I tried this method (as a starting point) on both Delta 3200 shot at 1600 and just now with Tri X 400 shot at 400. Two different cameras.

Both are so underdeveloped they are unprintable.

So I started looking around, and found people using basically the same thing I have been doing, on Tri X and getting good results:

what gives?

All from the same bottle of HC110 syrup.

Here is a 35mm acros developed this way:

Very few people use Tri-X at an EI of 400. It generally tests out closer to 160. This said, the Tri-x is underexposed by at least one stop. I can not speak to the Delta since I have never used it or other ultra speed films.
How old is your HC110 syrup? There is a possibility it has lost power or become contaminated. There is also is the possibility that you accidentally over-diluted the developer.

It is off by way more than one or two stops though. There is barely anything on the film. Can barely read Kodak. All of the above photos were developed separately using the same batch of developer one day apart. I mix one ounce of syrup in one gallon of water. When I use it I fill a one reel Paterson tank. And toss spent developer.

Eh? Yeah, it will "test" that way for zone system purposes but it's fine at box speed if developed appropriately. It's pretty good at higher than box speed in some developers. If HC-110 dilution G doesn't work well, try something else. I develop it in T-Max RS 1+5 or D76 1+1, shoot at 400, and I'm very satisfied with the negatives.

Does that mean that the film that looks like hell was developed using day-old developer? I get the feeling that working-strength developer is going to fade fairly quickly compared to stock or concentrate anyway, and if that working strength is something as dilute as dilution G, that may be your problem right there. I love dilution G and have standardized on it, but I mix it up and use it on the spot. I'd be wary of letting dilution G sit and using it the next day.

Roger thanks. I used TriX and D76 as my only film/dev for a number of years, and do like it. But I really like hc110 more than anything else I have tried. I would abandon it if others were not having great success with it at dilution G for TriX. But since they are having success using it, I would really like to figure out what I am doing wrong.

David - I hear what you are saying, but I have let mixed developer sit for up to one week and it was all good.

The 6x6 film was the first development on a fresh batch of gallon developer.

[steve barry]

It must be the film, all I can think of. I tried another roll in HC110 dilution B and got similar results. Does not explain the Delta.

I did notice last night when I was dumping the developer (after development was complete) there was a slight brown/red tint to the developer?

[Roger Cole]

What times are you using? While I've not used HC110 I've always read that Kodak's recommended times fir Tri-X in it are comically short and it needs much longer than Kodak says.

You have your answer in this response. "All of the above were developed separately using the same batch of developer one day apart."
This is a one shot developer. It's active developing agent is used up, or nearly so, with the first batch of film. Even if re-used immediately with a second batch of film it will likely result in under-development. It certainly will not keep overnight.
