Desperate but not serious
Rodinal for 100asa or slower, anything quicker is HC110.
I'm just about to get back into B&W processing after many, many years and this thread has been very helpful to me. I like the sound of HC-110, the shelf life being a big plus, but I understand it's quite a viscous solution. Is it difficult to dissolve fully, any tips? For instance is it better to mix (and how) at a higher temperature and let it cool before use?
Thanks Rob, extremely helpful tips for me to follow.In my limited experience, HC-110 is not difficult to mix. It is easier, for me, than mixing powdered chemicals.
I make up 500ml of working solution at a time--I use it in a Stearman SP-445 daylight tank--and it was a bit fiddly to measure the small amount I needed but, since I figured that out it is quick and repeatable.
I mix using water at my desired temperature and the HC-110 at room temp.
I use 1:31 ratio ( dilution B) which means 16ml HC-110 and 484 ml water.
I have a blunt tipped syringe marked in ml that I thought I'd use to measure the 16ml but that proved to not work very well because of the viscosity. What I did to solve that was to get a small plastic cup, use the syringe to measure 16ml of water, squirt that into the cup and mark the level. With that level marked I now just carefully pour the HC-110 to the mark.
I then rinse the HC-110 into my larger graduate with the water I'm using for my working solution. Once the small cup is well rinsed, I then simply add water to the larger vessel to the 500 ml mark. Mix in normal light and you'll be able to see whether or not the HC-110 is well mixed. And, the working solution will be a homogeneous, pale yellow-ish color.
Easier to do than to describe!
I will also suggest using the "Massive Dev Chart" as a good starting point for times/temps and there is a very useful "Volume Mixer" that makes getting your measurements quite a bit easier. See here:

Good luck and have fun!

So almost 18 months later, I've basically come to the conclusion that the difference a developer makes is harder to discern in most cases. For me, a good part of the problem lay in the variability of my hand agitated so-called technique. To fix this, I picked up a used Jobo, and yes, it fixed a lot of problems. There are certain types of low agitation, stand development approaches that a Jobo won't work with, but for many, it eliminates problems.
Even so, seeing the difference between an XTOL, ID-11, D-76 developer... takes a trained eye. Even Pyrocat-HD can be be less of a holy grail than it's often cracked up to be. While it won't be news to a lot of folks, I've come around to the position that 95% of our results won't be differentiated on the basis of developer or film choices, but by lighting and composition. Duh. So I've spent a year with the one film, one camera, one lens, one developer mantra... and there's a lot to be said for keeping it simple and focusing on what comes under the lens rather than the rest.
That said, which ones can make a difference in your confidence in getting the results you want. For me, the year's been all about Delta400, Rollei TLR 3.5F, and Bergger Berspeed. I've also used color: Portra400 and C41 (where the developer manufacturer doesn't matter all that much). C41 processing experience went a long way in terms of convincing me that there's a lot less value derived in these discussions than I'd have thought at the beginning. And Jobo literature will tend to convince you as well that the artsy fartsy agitation techniques have less merit than we want to believe as well.
To use the C41 podcast line, "Just go out and shoot some film, dang it!" Keep it simple and don't get lost in the details. Been there, done that. Glad to have moved on.

I didn't see what all the hubbub was about with HC110. It was "okay" but never got on with "the goo" and didn't see it as any better than D-76, so why bother?
Well, that's good enough for me. Thank you very much.Not even slightly difficult to mix into water. It is 100% water soluble and goes into water with even the most minimal agitation. The viscosity of HC-110 is higher than water but extremely low by any other standard. I use a simple 3ml syringe to add it to water. Takes about 45 seconds to measure, add, and mix into 20 C water.
Rob:
One of the great things I enjoyed playing with in HC-110 is the level of dilution to use. I don't know whether there's a more flexible developer out there. It's amazing stuff! The only thing I didn't like was that the viscosity is so thick, and the stuff ran so slowing out of the bottle and into the beaker, that I used to worry whether I had too much or too little. Truth is that precision isn't all its cracked up to be. You gotta be close, but you don't have to be precise or you're gonna ding dang dong die. But I only came to that with experience... experience of making mistakes and the stuff still turned out fine.
BTW, I like the shots you've linked to. Yep: you could develop with shoe polish and your content would still look great. Don't do it! Just saying.
