I've had a copy for some time (as regular readers will know) and think it is
an excellent buy.
Some illustrations of interesting work produced with the process also, and
interviews. I haven't seen anything else that covers the area so well or
clearly.
As I've said before, highly recommended - almost essential reading if you
are starting work with these emulsions.
