Marc,(posted 8145 days ago)Like you, I'm a pretty devoted XTOL and Rodinal user. I got some DD-X the other day and developed some Delta 400p so that I could see how it worked. I started at the bottle recommended times and the film came out waaay too thin. I'm pretty sure I got all other parameters (tem, agitation, etc) right. You might test it on test film first, as you find your times.
