You say that your recommended tomes for Plus-X, at EI 100, developed in Agfa 17 1:1 at 72º F is 20 minutes.

I haven't tried Plus-X yet in Agfa 17, but the times for Efke films and Ilford Pan F+ isn't much longer than with D-76. I have used Agfa 17 1+1 at 20ºC for 9 minutes with Efke R 50 and Ilford Pan F+, and found it to be right. The recommeded times for same films in D-76 is 8 and 8 ½ minutes.

Are you really sure that 20 minutes is correct? At 20ºC the times would be 21-22 min.

Patric--It has been 10 years at least since I tested Agfa 17 with Plus X. When I get home I will look through my negatives again and see if I can find any notes on this combination.

Patric. The Plus-X in Agfa 17 was done in 1989. I note there is a roll before the one at 20 minutes that was developed for 45 minutes in Agfa 17 (1:1), and is extremely overdeveloped. I can't imagine why I would use such a long developing time unless I were testing reduced agitation. The next roll, developed for 20 minutes at 72 degrees looks very nice. I suspect that I reduced agitation to maybe once every two minutes, but I didn't record it. Let us know your results

Thanks. I have a roll of Plus-X that's waiting for the soup. I will try Agfa 17, 1+1 at 20ºC for 10 minutes and see how it turns out.

Hi! Just to post times for Agfa APX 100. I've tested it in Agfa 17 a few years ago (and didn't use it for a few years, too) and got the following results: 5 min (beta=0,5; 21 DIN) 8 min (beta=0,6; 22,5 DIN) 13 min (beta=0,75; 24 DIN) Agitation: Const. for the first minute, then every 30 sec.

Alex, was the developer straight or diluted? I don't think I will try Agfa 17 with APX 100 because it's too close to D-76 and I have never got good results with that developer and APX 100.

-- Patric (jenspatricdahlen@hotmail.com), April 26, 2002.

I developed my first roll of PX in Agfa 17, and 11-12 minutes at 20ºC seem correct.

Ed, your times for Efke films in Rodinal are too long as well...

This is my times for Rodinal 1+50 at 20ºC

Efke 25 4-4½ min Efke 50 4½ min Efke 100 5 - 5½ min

-- Patric (jenspatricdahlen@hotmail.com), April 29, 2002.

Patric, it was in straight developer.
