I remember running out of developer and looking up formulas to mix up enough to get me through the weekend.
A $100 or smaller investment in a balance might be in line, if the formulas are published.
I suppose it will also depend upon how exotic the required components turn out as well, but it might not be too difficult.
I had a visit from a former student who had an advanced degree in photography, and he had enough chemistry to adjust or compound a number of developers.
Could be a good subject for a book by Roger? But I have not researched what is out there at present. My good friend Jan from Berlin seems to know many of the formulas through research.
He also tells me that many older formulas were made available in the former Eastern block countries??
