I have wondered how the old films handled low light. I assume the films used in the 1940's were slow by today's standards so how they achieve focus and lighting so well has always caught my attention. I already had the box set to record Casablanca tonight. Joe
The light level was quite high in most scenes. A lot of the light came from carbon arc lights, 10,000 Watt and 5,000 Watt tungsten as well. . (Here's a little clip on the Mole Richardson carbon arc brute you might enjoy - https://www.youtube.com/watch?v=9d7bsCiRFLE )
Although the arc brute came after Casablanca very similar lights were used. The lighting directors really knew how to light back then and used contrast in lighting and exposure to control the look.
I agree these old films shot on B&W negative and printed on fine grain release stock were beautiful.
