Thanks Mustafa,
One of the dyes is difficult to get in the USA. If I remember correctly, it was the iodide. Sigma would not sell it to me, even back when they would sell some dyes to individuals. It is harder now.
Jeff Blyth is a realy good guy. We have corresponded and he even sent me some of the dye I was having trouble buying. I wonder if the dyes reccomended by PE, SDA3057 and SDE3008 , for red and green sensitivity,respectively, would work in this system. They are mucho expensive, but they do work for panchromatic sensitivity.
