Old photos are generally meant to be black and white. However, we have some photos from the 20th century where color photography has proven to be in existence for longer than we thought it would be.
Before 1907, some different dyes and pigments were to be used if an individual wanted color photos. However, Auguste and Loius Lumiere, two brothers from France, changed the world with the technique they introduced, known as Autochrome Lumiere. It made use of dyed potato grains and starch to come up with light-sensitive emulsion and it resulted in vibrant photos being produced without having to spend much time and effort to color it. The sad part was that they were not able to prove themselves scalable. Nevertheless, they were famous in the amateur photography industry.
It was only when Kodak came into the picture that it was revolutionized at a different level and Kodachrome became popular.
