Rodinal Stand Development - advice needed

DNG said:
OK, Tried using 2ml for 300ml water... Not enough, Exhausted too soon,

: :

Back to 3ml per 300ml of water
BUT, I will try 4ml to 400ml water next. just to see if it is better than 3ml/300ml.

Let me say this again: the quantity of water doesn't matter for stand, as long as you cover the film. Dilution is not the right metric, Rodinal quantity is. At nominal speed, use 3ml for one 35mm roll. For 2 rolls use 6, etc. To push one stop and one roll, use 4-5. If you use less (2ml) you are pulling.

I knew about the "Per 300ml dilution..
But, I did not know about changing the amount of Rodinal according the ISO used... Good to know.

I just did a roll of FN400 at 500, and added 1ml, but used 400ml (which doesn't matter apparently) Negs are scanning real nice at 4500dpi/4 passes. And they look good too. And lower grain also... than at 3ml.
 
I have been reading up on stand development for a few weeks and tried it for the first time today. I used 1:100 and developed TMax 400 film for one hour with one minute agitation for the first minute and 30 seconds after 30 minutes. The temperature was around 72F. To be honest I was surprised with the result. The negatives had excellent contrast and scanned very well. The grain was remarkably fine compared with my normal 1:50 films.
I will post some pictures soon.
The second film was just as good.
 
If you used a 1:100 dilution, how many ml of rodinal were in the tank total per roll of film? There seems to be an idea that say 500 ml used for one roll is different than 300 ml used for one roll - that it is the amount of developer per roll that is relevant. I'm just curious. I hope to develop some in the next few days.
 
Since stand exhausts the developer when done right, the amount of water doesn't matter. Usually people say 1:100 and refer to 300ml water. When they really mean 3ml per roll ....
 
That's why I asked. In the photos I posted, I mixed 500ml @ 1:100 and then filled a two reel tank that only had one roll of film. So effectively I had 5ml for that roll.
 
For me that would be equivalent to pushing by 1 stop, SA. It all depends on how you expose and scan, however - if you develop for scanning, that is. I expose for shadows, mostly, and try to get a good level distribution right from the start, after scanning. Like this:
