Rodinal 1+50: How much for 1 roll?

Tri-X at 3200 with rodinal 1+50

Tri-X at 3200 with rodinal 1+50

Here's my first time results with tri-x at 3200 souped 30mins. in rodinal 1+50 (10ml+500ml water btw). Two inversions every 3 mins.

I may need to develop more films (haven't done any for the last 18 years or so) but I like what I got so far, I prefer it to tmax3200...

Hi folks,
I've read a bunch of old posts regarding pushing TriX to EI 3200 using a 1+50 dilution of Rodinal and souping for 30min. In my tank, it can hold up to 570ml.

For a simple 1+50 dilution for 1 roll of film, would I use 510ml of the 1+50 soution for 1 roll of film?

-or-

Would I use the amount that the tank requires for 1 roll of film (270ml I believe) out of the 510ml of mixed solution?

I believe that it is the prior, I would use 510ml of the 1+50 solution for 1 roll, but want to verify before I soup it tonight. It is counter-intuitive compared to all of the other developers out there, you mix a litre of the various solutions and then use only the amount required by the tank.

Thanks!

Hi Paul,

This is a question that always gets a lot of answers due to the fact that Rodinal is such a versatile developer. As you can see, there is no single "RIGHT" way to use rodinal. I have found that I like to use Rodinal 1+50 for 35mm films and at 1+100 for 120 films. This way I am using 5ml of Rodinal per each roll of film. I also like to use longer developing times with agitation intervals of two gentle inversions every 5 minutes. This works beautifully for me, and that is what's important, to me.
