More specifically I mean were there filming techniques that worked well in black and white that no longer worked with color film? I'm just curious how the physical process of shooting a motion picture was changed.
Technicolor required very intense lighting. It was a three-color process, so there was a color filter in front of each of the three strips of film to allow only one color light for each. As a result, the film had an ASA of only 5 and the lights had to be very bright. The three-strip camera also was enormous. So, mostly shots had to be done in a studio, not outdoors. Perhaps the most famous film to use it was the Wizard of Oz, which required many actors in very heavy makeup and elaborate costumes to perform at temperatures of around 100 degrees F. The most afflicted probably was Bert Lahr, in his furry Cowardly Lion costume.
The George Eastman Museum has a good short video on the Technicolor process.
