Comments: All are for Jobo rotary agitation, one-minute prerinse to avoid airbells. [D-76H omits the hydroquinone and increases the metol to 2.5 grams.]

Comments: I give 30 seconds initial agitation, followed by 5 seconds agitation (2 inversions) every 30 seconds. This time is for a diffusion enlarger. * This is using the metol
version of Pyrocat-HD.

Comments: Exposure is generally with a Weston II and Zone System. PVC pipe spacers are used to put the 35mm material in the center of a 450ml tank, thinner spacers in the top/bot of
120mm keep the reel from rattling about during inversions. Inversions every 15 seconds per Hutchings’ Book of Pyro. N- and N+ developments are about 1 minute (-/+) from this 11 minute
base. If someone is interested in a heavier than "normal" stain (almost brown), the Pyro mix can be "aged" for 8-10 hours before using.

Comments: Gentle continuous agitation for the first 30 seconds, then 4 inversions every minute. I rate it at 50 only on bright, sunny days.
