Documentary of the scientific processes of film and video on a molecular/chemical/electronic/binary level.

I have been searching far and wide. Can anyone shine some light? I'm looking for anyone who has an understanding of the technical processes of film and video on the smallest and most complex levels for a documentary I'm making. Any suggestions; websites, books, documentaries, and people who could shine light on the matter would be very appreciated. Specifically someone who could explain what film is doing, with detail, chemically. More understanding means better technology and advances. Thank you!
