Sharing from peronal expereince, the time listed at Digitaltruth.com for Tri-X in rodinal 1:50 at 18.5 minutes is not recommened. The roll I shot 2 days ago is drying with 3 possibly usable frames. But I'll scan them tommrow. In the past I would probably be pissed about the result but somehow I am fine with it these days. The fact of shooting film gives such result a true appriciation for a developed roll.
I have been reminded by Pope John Paul II greatness in the last 24 hours. Its now been 2 years and the time of his death I was in Poland feeling the loss. The whole country came together. It was(is) an amazing place in the world to be and feel powerful events.
