Ed Buffaloe’s Recommendations for Agfa APX 400

Developer

Dilution

Time

Temperature

E.I.
Rodinal 1:75 12 m 70° F 200
PMK 1:2:100 13.5 m 70° F 200
PMK+ 1:2:100 14 m 70° F 320
HC-110 B (1:31) 9 m 70° F 400
Comments:  For Rodinal and HC-110 continuous agitation for first 30 seconds, then 10 seconds (4 inversions) per minute thereafter.  For PMK and PMK+ continuous agitation for first 30 seconds, then 5 seconds (2 inversions) every 30 seconds thereafter.  This isn’t my favorite 400 speed film, but it is cheap (in the U.S.) and I have used it a lot and gotten excellent results with it.

Rodinal Special (Studional) 1:30  (16ml + 484ml) 9 m 30 s 20° C 200
Rodinal Special (Studional) 1:30  (16ml + 484ml) 11 m 20° C 400
Comments:  Gentle continuous agitation for the first 30 seconds, then 2 inversions every minute.
Rodinal Special gives me finer grain compared to Rodinal, but a little bit less sharpness.  Don't expect miracles with APX400 at E.I.400, but Rodinal Special does a good job. I find that the 1:30 dilution works better than the recommended 1:15.
