Dear Dan,
According to Christopher James, "it keeps indefinitely if stored in a
dark glass bottle and kept away from excessive heat and light" (see his
book).
As I mixed my first batch of Cyanotypes chemicals previous week, I'm
unfortunately not able to confirm that claim (BTW, I must state that I
see Mr. James as a very reliable/trustworthy source of information).
Can you please share your experiences on [digital negatives - cyanotype]
combo later? I will try the spectral density negative method - that
you've described in your book - this weekend. I prepared a negative on
Epson transparency media - will try to build a good working adjustment
curve...
Regards,
Loris.
