(My) Film development times

My personal film development times. Temp is 20°C if not explicitly stated otherwise.

Notes:

^[1] Not verified by o.d. measurements. Looks quite OK. Only tested once, 2022-01-30. Edit 2022-02-09: From transmission measurements it seems like 11:00 is actually a suitable choice for *normal* (N) development !?

^[2] Preliminary, need further testing. Agfa suggests 8:00@EI125. Ilford suggests 9:00@EI125

^[3] Dev-time 10:30 tested and worked quite well judging from contact sheets. Transmission densities from last batch (Jan 2022), however, indicate density is actually a bit low. UPDATE: Test on “test-neg” from 2022-07-20 indicated 12:30 is more appropriate.

^[4] Time verified by o.d. measurements on test negative. I used to developer for shorter times, approx 10:00

^[5] Not verified by o.d. measurements, but contact sheets looks fine (OK shadow density and overall contrast). If anything, the time should be increased and not decreased. Even better is probably to let time be and use EI 50 instead?
