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.
