I understand now. Thank you for alleviating my confusion.
I think that it would be a wonderful thing to have, though. You raised an interesting idea for me. I do have one of the Zone VI compensating timers that I had purchased for a cold light application, but I never used it. I wonder if a person could obtain the photocell from Calumet (I understand that they are still available). and fashion a retainer in the light path of the light source for contact printing?
What is your reaction to that idea? Would it work? Please give me your thoughts on the matter. Thanks.
