off the shelf is based upon hydroquinone's infectious
development in a very low sulfite environment.
I'll likely get back to compounding my own although for
the near future my time available for darkroom work
is very limited. I'd like to explore the developer as
a global contrast control. Have you done any
exploring along those lines? Perhaps lith
then bleach then redevelop? Or even
Not as yet. Processing ILFORD MGWT in a standard PQ developer, bleaching, and then redeveloping in a lith developer is planned, as suggested by Tim Rudman.
