I've been using Kodak HC-110 developer in a small tank for film processing. For the last 2 sessions, I was using T-Max 400. One session produced negatives that had a purplish tint (which I don't think is right). The other session produced more normal looking negs (black, grey, clear). I've looked over the "J" sheet for HC-110 and I don't see anything about agitaion. I think when I used other develpers, I was told to agitate for the first 30 seconds and then 5 seconds every 30 seconds. However, during the first session I may have forgotten the pattern and only agitated for the first 5 or 10 seconds and then every 30 seconds for 5 seconds. Does anyone have any recommendations for an agitation pattern using this developer in a small canister?
