I had a pretty successfull trial run stand developing Acros in Photographers Formulary's modified version of FX-2, TFX-2. I doubled the dilution. Aggitated for one minute and again at thirty minutes, then full stand for another hour. Hour and a half total. I forgot about presoaking, and I did get what look like tiny airbells. I also worry about uneven development with stand developing in general. Now I'd like to try semi stand development, aggitating perhaps every tenth minute. I do not have a 'normal' development time for this combo to begin from, so could anyone reccommend a good place to start for ten minute aggitation intervals backed off from my 1 1/2 hour stand time? Normal times for many films in TFX-2 are pretty long, in the 15-20+ minute range. Thanks!
