HC-110 is an amazingly versatile developer, given how it can be predictably used at significantly different dilutions. It also lasts a long time in concentrate form. I employ it for certain technical applications of TMax and other films in the lab. For general shooting, I prefer PMK pyro.
Times per massive development chart.
Tanks: Paterson Roll 120 and 35mm, SP 45, MOD54 insert in Paterson
Dilution B for times 6 minutes and more.
Dilution H for films where MDC Dilution B times would be less than 6 minutes.
Agitation:gentle inversions for about 10 sec once every minute.
Hope this helps.
