Hi Kirk,
I might consider selling a few dozen mg of the spectral dyes to you,as you are a fellow insect fan. As of yet, I have not opened the vials they came in. They are tucked in a dark corner of a freezer.
As for testing the spectral sensitivity of my future emulsions, I intend to place a Kodak color chart transparency over the emulsion,which has been coated on glass, and expose with pops of a strobe. Thats as close to white light as I can get, ouside of going outside.
As fof your T-grain emulsions, I thought that was your baby! I am waiting for your initiative.
