I'm not much given by nature or training to act that way. I've got a number of lovely handmade panchromatic film negatives and glass dry plates on my light table.

Denise, I agree. However, I must ask if you have wedge spectrograms of your pan emulsions showing good red sensitivity? This would be hard scientific evidence that it works. If you don't, I would be happy to expose a few of your plates for you and return them to you for processing, as I have a Spectro Sensitometer. That is the ultimate proof.
