This graphic gives us an idea of how seamlessly the movie magicians can patch together a scene made up of live footage and a matte painting. Here we have Judy Garland as Dorothy Gale running down a dirt road with her little dog, Toto in “The Wizard of Oz.” (1939) On the soundstage, they only needed to build the dirt road and some of the fencing. The rest of the scene was filled in by the talents of a masterful artist. In post-production, an editor flawlessly pieces the two elements together, and voila! We have that gloriously sepia image.
