Depending on what music is playing, I "might" roll a bit harder . I am currently using D-D23 and I think I did this one at 4 minutes in A and 6 minutes in B (I'd have to check my log). I've slowly been working towards getting harder/darker/denser negatives so that I can contact print and have adequate time for burning, dodging etc. I'm up to an average of about two minutes exposure (from 20-40 seconds) on AZO Gr2. This negative is about #35 from this old camera and #135 since I started in photography. The first 100 were mostly FP4+ in a Calumet 400 monorail. Now I'm using an Agfa Ansco 8x10 field camera made in 1941. The film is kodak PlusX Aero cut from 9.5" x 125' rolls.
cheers and thanks again - I'll watch my agitation a bit more carefully from now on, just in case.
