Mixed Filters

photographers often use orange and red fi lters to cancel blue and green, making skies dark and foliage rich in tone. Careful selection of these color fi lters allows the photographer to decide which colors in the image will produce the brightest or darkest tones.

How color fi lters in black and white make color fi lm

Even when photography was only black and white, visionaries were already laying the foundations to move photography into color. In the 1860s, less than 30 years after the introduction of Daguerreotype, the method of using color fi lters with black and white fi lm was utilized by James Clerk Maxwell, who experimented with a three-image projection process to create a color image from black and white fi lm. He presumed that a color image could be created by exposing three monochrome images of the same subject, exposing each using a diff erent color fi lter before the lens. Each of the red, blue and green fi ltered exposures was then projected using three lanterns, each equipped with the corresponding colored fi lter. The red and green fi lter together created a yellow image, and all the three colors together created a white image. The fi nal image, although far from perfect, included all of the original colors in the subject. This experimentation laid the foundation for not only color photography but also the Technicolor process used well into the 21st century to create movies in color.
