Digital may look great, but all this talk of different film stocks and speeds makes me wonder if we haven't lost something of the art of photography. You could do some really lovely things with different camera's, lenses and film back then. Isn't it all a bit 'vanilla' these days?
You should check out the movie "Samsara."
Filmed in 70mm, it's the most beautiful film I've ever seen. The movie was shot on film, then digital tech was used to scan the film at 8K. I'd like this to be the future of film -- not replacing film with digital tech, but using digital tech as a tool to make the most vivid, detailed masters possible.
