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.
