I received your formulary. Thank you and congratulations! Its an amazing piece of work. I will talk to my friends and will reply you as soon as I have something done.

You say "Note also that the latent image properties for reversal films are not long lived". On "latent image" you say the film BEFORE developing? Is that it? If so I may have a problem because since the E-6 developing costs skyrocketed in Brazil I stopped sending the films to develop and keep them frozen (-18C).

I have films from 2 years ago. Do you think I may lose something because of the age?

Thank you.
