First, this is black and white LITHO film, not color film.  Second, it has NOT been exposed to any stray light, and I am using the recommended safe light as per the Kodak spec sheet.

It is VERY VERY subdued, so after getting adjusted to the light, I can BARELY see what I am doing.

This film is only about 8 years old.  I have been using Agfa film with no problem for years, my batch is now 13 years old.

I can clearly see the film develops fine, and only turns reddish-orange when put in the fixer.

Thanks,
