My evaluation of the negatives suggests that there was only just enough shadow information to be truly usable, so I don't think overexposure was the issue. But I haven't used 2B-1 with a film like HR-50, which I will probably do soon.I still think you over exposed the negatives you did in 2B-1. It's giving a speed boost and needs less exposure. Your highlights will be hard if you over expose it (and develop normally). You can see in this thread above how well my two baths (2B-1 and 2B-4) did with HR-50. Since you already cut your dev time to as low as makes sense, less exposure is the next step.
Of course if it's not the tool for you it's not the tool. But it might be for others.
If the developer is doing its job, (IME it does) with the proper exposure and development, you're not going to lose shadow detail at the expense of blown highlights. This developer will retain the shadow detail, that is where a divided developer shines. If you are experiencing blown highlights, my assessment is still that you didn't dial it in yet. But you have no obligation to do that. I'm only defending my work in the face of statements that your result is how it is.My evaluation of the negatives suggests that there was only just enough shadow information to be truly usable, so I don't think overexposure was the issue.

See above comnents. IME you did not dial in the exposure and times yet. But again, if you like what you have, no need to.For my needs, no matter how much exposure the film got, highlights shouldn't be getting too hot in a divided developer.
My tests involved bracketing upon to 1&1/2 stops plus and minus, and the minus frames lacked any shadow information, but the high values were hotter than I prefer. (I didn't say the highlights were "blown", I just said they were too hot for my liking)If the developer is doing its job, (IME it does) with the proper exposure and development, you're not going to lose shadow detail at the expense of blown highlights.

As I said, 2B-1 will work well for many people, depending on what they want to achieve. But it's too active a developer for my needs.
I'm heading back up to my cottage where most of my chemicals are tomorrow morning and will mix a batch of 2B-1 up to test it against BTTB. I find HR-50 in BTTB a very good combination, but I would never turn down a little increase in film speed as long as it doesn't take a toll on image quality. We'll see, I guess.
Give it a shot John. I liked my results with it, as posted. For me, achieving box speed and retaining as much shadow detail as possible were key positives.
Very nice indeed! I haven't used HC 110 since college in the late 70's-early 80's. Then it was only dil. B.
Aviphot 80 worked great in Rodinal 1+50 or 1+100HR-50 is an Aviphot 80 derivative which has a contrast intermediate between "ordinary" film and Adox CMS20.
In the data sheet Adox suggest developing it in dilute FX-39 II or Ilford DDX:
It may do well in some other diluted developer eg, dilute Xtol or Perceptol.
John,i use pyro-M with hr-50 and it comes out very good. I use the standard 1+1+100 dilution and shoot the film at 50. 72 degrees, 15 min, 1 min initial agitation then 10 seconds every 3 min. get much better results then i did with RR80. so, for me, their speed boost does what it claims. i had mostly used hr-50 and rr80 for slides. I never liked the high contrast i got with rr-80 as a negative, but hr-50 is great for me in pyro_m as a neg. I also used it in Alans cd4-lc with good results

John,
I take it Pyro-M is Pyrocat-M or MC? I tried it with Pyrocat-HDC and it was fine, but I actually thought Barry Thornton's 2-bath worked better for me. I won't be playing with these films until Spring rolls around again.
BT 2-bath is pretty simple to mix and contrast can be controlled somewhat by bath B dilution and differences of agitation/time. I think AA used a similar 2-bath Stoeckler version with different B-bath dilutions or borax, sodium carbonate?yes, Pyrocat-M. I prefer metol based developers over phenidone. i pretty much use it for all my neg films, so i have it dialed in. i have wanted to try thorton 2 bath, i have the books and read them every once in a while, but I have never mixed it up. I'll give it a try when the weather gets better and shoot a few rolls to try it. thanks for the idea
