After years of processing film we have three basic standards
D76 - for low light and normal lighting conditions,, end uses are varied but I
like pushing a bit the dev and printing lith or solarizations with this dev.
Pyro- our standard developer for strong lighting conditions.. we recommend over exposure by one stop minimum and we develop accordingly.
HC110- multi purpose developer with different dilutions and times.
this is a go to developer with tri x for lith negs. under expose over develop.
this is the developer I process my film from the image recorder.
this is the developer I used for enlarged negative applications.
All three are amazing developers if used for the intended purpose.
