A while back PE wrote of one of his connections possibly producing some dyes for Emulsion Makers. I wonder, is this still possible.
If I have no alternative, I will buy more of the SDA3057. For my work, nothing but panchromatic emulsions will do. I have been evaluating some dyes. But none do as well as "J Agrigated" SDA3057.
Believe it or not, chlorophyll, freshly extracted from spinach, shows some red sensitivity, but nothing like SDA3057.
Just Dreaming,
What in the heck kind of ANYTHING on this earth could cost $16,800 an ounce? That doesn't make sense. What good could it have possibly have been even to a company like Kodak was in film manufacture at a crazy price like that. Surely there is another reasonable alternative to making film panchro.
