I thought I had posted this to the articles a long time ago, but I guess I didn't. So for the archives and the children, here it is.
I like Hc110. Especially for roll film. I don't like the convoluted "working
solution" dilutions and sub dilutions, or the short times some of the dilutions
and sub dilutions create. It should be simple to use Hc110, like Rodinal.
If you care to research, there was a method to Kodaks madness when they
created the dilutions and routines for HC110,...
JBRUNNER, thanks for this. Sorry if this has been asked before, but I noted that TMax 100 and TMax 400 have the same dev dilution but yet have the same dev time. How can this be? I would think there would be some difference??
They are not the same emulsions.
I think I have found an easier way to measure the stuff. I saved an empty dish-wash soap bottle, thoroughly rinsed it, and filled it with HC-110. I have a little graduate that goes to 100, and I fill it with water to 88. (I even put a little mark on it at 88). I then hold the squeeze bottle upside down and slowly squirt in the developer until the level is at 100. I need 600 mls, so it's 12+588. As soon as you stop squeezing the bottle, the flow stops, no mess. The little graduate is dumped into the big one, rinsed out a few times with water, which is added to the big one, and then it's filled to 600 mls. The little thing on the cap of the bottle even snaps shut.
Best of all, it was free.
Just seemed odd that other developers indicated diffs of a minute when used with TMax 100 vs 400.
Jason, what minimum amount of developer per roll do you recommend? I found two recommendations one says 3ml another 6ml.
JBrunner,
What do you like about HC110? I used to use it and found it nice as super diluted compensating developer and use to have a great method for pushing HP5 with semistand. I've since switched to X-Tol and pyrocat hd. I'm just curious to why you like it for roll film. I do really love working with concentrated developers.

My apologies, I thought you were thinking it was the same emulsion at different speeds.
It is actually quite a good question in regard to developing regimens, so I hope to give a better answer, and address a little mantra of mine, in the context of thinking people need to realize that the key to success in the darkroom is being consistent enough to have verifiable cause and effect, and that that is so incredibly more important than following what some hippie from Utard advises as a time, as to be possibly one of the most under sung magic bullets yet devised.
So, the times are just my times, what I like for a particular emulsion, so they aren't meant to be holy writ, just a guide for people to start with. Also, im thinking a minute more or less in a nine minute development scheme doesn't amount to a difference most people can discerne.I probaby cooked one at nine and tried it for the other with good results and wrote it down. All of the times will in my experience yeild good usable negatives, but adjustments should be made by the individual to achieve their own version of negative nirvana. One might find 12 minutes more satisfactory, and that would be fine by me.

I'm really not clear what problem you're trying to solve. Making a 1:49 dilution doesn't make anything easier than a 1:31 or 1:63 or 1:119 dilution, as far as I can tell?
