One of blind believe is that past is black & white.Many of us can forget that the past was also in full color because we just don’t get to see it.
Color photography was not possible at the time, but it was possible to create a color image for the viewer by completing three separate photographs. One had to take three separate photographs of the same subject – once with a red filter over the lens, once with a green filter, and once with a blue filter (red, green, blue – RGB – is a set of color channels used by many digital images as well). In the next stage these three monochromatic images would be projected through filters of those same colors onto a screen and superimposed. When viewed through a final filter, they would appear as a realistic color image to the viewer.
