I’m a huge fan of seeing photos from France in Paris in the distant past and 100 years ago is amazing to see how much is different and how much hasn’t changed.
These colored photos by Jules Gervais-Courtellemont will take you back through time to see how Paris looked in 1923. The vivid images are produced using the autochrome technique in which the plates are covered in microscopic red, green and blue colored potato starch grains (about four million per square inch).
When the photograph is taken, light passes through these color filters to the photographic emulsion. The plate is processed to produce positive transparency. Light, passing through the colored starch grains, combines to recreate a full-color image of the original subject.
