Final answer:
Most films started being made in color during the 1930s, thanks to advancements in photographic technology such as Kodachrome by Kodak and Agfacolor Neu by Agfa. These technologies employed a multilayer emulsion process that is still relevant in today's color films.
Step-by-step explanation:
The transition to colour films became prominent in the 1930s. Technological advancements such as Kodachrome, introduced by Kodak in 1935, and Agfacolor Neu by Agfa in 1936, facilitated the proliferation of colour photography and subsequently colour cinematography. These color films used a multilayer emulsion process that resembled Agfa's, and most modern color films still use similar technology today.The film industry experienced a significant shift during this era with the integration of both color and sound into feature films. This technological evolution not only transformed the way stories were told on screen, but it also unified audiences in theaters and marked the beginning of a widespread cultural phenomenon. The advancements in photographic technology dating back to the nineteenth century, along with the rise of methods like CGI in later years, have continually shaped the way films are produced and experienced.
