color and sound

Color was revolutionizing film in the late 1930s. In the Wizard of Oz the emerald city was used to show off this new technology of shooting film on three different filters to combine and create a colored screen. Color made focus shift to whole other businesses of the trade like costuming and makeup.

Sound was interesting because deison was trying for sound on his old recordings too. The first talking picture was the jazz singer. In singing in the rain it explores all of the problems with the first few sound movies. the way that the soound was not matching up with the actors mouths reminded me of the later problems with translating foreign karate films to make the mouths match up and even later, the way sound and picture still might not match up on netflix while it loads. I think having sound and imag be two different tracks is a problem because of the possible delays but it must be done to keep the layers of a film intact.
