Hi all i have just tried push processing Tri-X 400 @ 3200. Just to ask some beginner question as i have trouble trying to sort it out. I tried developing Tri-X in DDX @ abt 18mins @ 20C with agitations every min(Could find the timings anywhere so just tried to infer the correct timing by basing it on the timing for 400 and adding abt 2.25 times more). The negatives i got back, are primarily clear ( I was shooting a concert so there were lots of black parts). Now i know the negatives are underexposed due to me pushing 3 stops, and the developing time has been increased. So i would like to ask is the negative that i got back correct? As i am still experimenting i would like to know how to proceed next in order to develope Tri-X in DDX. Should i develope shorter or longer the next time i try to push tri-x. Or should i not agitate as much to bring out the shadow details (some form of stand developing)?
