Photo Chemistry: The silver behind the silver screen

We have megapixel cameras in our phones and gigapixel cameras on our telescopes.  Before digital took over photography (and the world,) we had film.  Light struck silver and made a mark and behind it all was some marvelous physical chemistry.  It is still awe-inspiring to think of how these processes came about when knowledge and instrumentation were not nearly as advanced as today.  Each step could have millions of alternatives and sorting them through brute force would take the age of the universe.  Yet somehow it all came together and spawned industries.  The American Chemical Society takes us through the science as it was in 1940.
