There is as much new work as old to cover, and the rest of the process is not covered well in existing books. I've said before that fixers, stops and the other solutions are useful material for incorporation into a book.
Those are all in the pipeline much data already prepared, I did a lot of work on Toners for instance for commercial reasons back in the 70's & 80's and here again it's a case of not trying to re-write Tim Rudmans books but add something extra.
Over the years I've done a lot of research and archived it away, countless Patents etc, and some very interesting developer formulae that need trying and testing, taht are unlike anything published in existing books.
Some of the formulae I'm not so interested in now, that's the emulsion & alternative processes, but rather than let them go to waste sat on my PC (& on film or in books still) I'll pass them on to someone like Denise Ross rather than let them go to waste. There shouldn't be anything you haven't already got somewhere or other, but there's some Formulae for POP etc that she'd probably like to put on The Light Farm. Maybe someone like Kirk Keyes might like to transpose them to a text format first.
Most of what I need is ready,,some needs editing, Gerald Koch & Tom Hoskinson were going to do the cross checking and validating, and add one or two I'd missed. Now it's really just a case of designing a good way of making the data available.
