In 1861, by Scottish physicist James Clerk Maxwell and his assistant Thomas Sutton. Maxwell conducted studies on how the human eye perceives colors. Based on them, he used the existing techniques of black and white photography to take three identical photos of the same object, each through a different filter: red, green and blue. Then, using lamps with filters of the same colors used in the capture, he aligned the results on a screen. The generated image was in color. In fact, the Scotsman’s technique had some essential flaws, such as capturing blue much more than green and the practically non-existence of red – the pink you see in the image is an accidental capture of ultraviolet light. But his three-color method influences photography to this day: RGB technology is inspired by him. In 1903, the Autochrome Lumière method appeared, the first that allowed taking color photos with just one (long) click.
