Recently I've developed a few rolls of Arista Premium 400 (rebranded Tri-X) that I shot in 2016 and put away on shelf without freezing. The expiration date of the films is 2013 -- they had always been frozen before I shot them.

I tried normal development for several rolls and pull development two rolls (just curious) in the past week but the results were just "boring" (a.k.a. normal). So yesterday I decided to experiment stand development with HC-110.

It has been well established that one roll of 36 exp 35mm film requires minimal 3ml HC-110 syrup for one shot development. Typically, I used dilution H and made 480ml developer solution from 7.5ml syrup. This solution allowed me to develop two rolls of 36 exp 35mm film in a 500ml stainless steel tank. It had worked very well in the past.

Call me cheap, I have always been wondering whether it is possible to use even less syrup, which would cut my negligible cost on the developer even further! I know many of you probably are already rolling your eyes at me. That's OK. Heck, even if it fails, it's just a small lesson of don't be cheap!

The true reason to use even less syrup is to make further dilution and still fit into the 500ml stainless steel tank. So after researching a lot online with no conclusive result, I decided to conduct an experiment yesterday.

I diluted 5ml syrup into 500ml developer AND soaked two rolls of 36 exp 35mm films. The temperature at the beginning of the development was 70F. After initial agitation of 30 seconds, I put the tank in the refrigerator for 40 minutes. At 20 minutes mark, I gently agitated the tank twice.

The result floors me! The contrast, the well-controlled highlight, the deep shadow, and the grain are among the best I've ever got out of Tri-X. The pictures really shine in front of the other rolls developed last week. The only flaw that I can see is some small highlight at the edge of some pictures, which looks like a bit light leak. I got this similar issue a few years ago when I tried stand development with Rodinal. Haven't figured out how to solve it.

At this moment, it is hard to say whether it's because the subjects of these two rolls were well thought through to make the pictures stand out, or the development method is the magic bullet. But I will definitely try this method again -- still have several rolls of Agfa APX 100 and Plus-X to go!

A few samples:

The negs(scans of negs or scans of prints?) look good. What was the temperature of the HC110 by the end of the time? Is it the period in the fridge that you believe has made the difference. I say temperature difference because I assume that this is the crucial change in the process as far as you are concerned

I’m seeing some non-uniformity, along with blank shadows/high contrast (the shadows could be due to exposure also). But that’s just me.

The blank shadows could be from a combination of shooting at box speed (an assumption on my part as the OP doesn't say which EI he used), and stand development. If stand or semi-stand is intended, one must give amble exposure, especially with Tri-X's longish toe.

These are scans of negatives -- I don't have a darkroom or equipments to print yet. And I don't know the temperature of HC-110 by the end of the time. People claimed that temperature didn't matter much for stand development so I didn't bother checking it. The refrig was set to 38F, but I doubt that HC-110 would reach this low at the end of the development.

I believe I shot mostly at box speed but in many scenarios I simply guessed the exposures, or arbitrarily increased exposure by my taste. And it has been five years since I shot them.
