Photographer Jules Gervais-Courtellemont mastered the technique of taking colour photographs using Autochrome, an early process patented some 20 years early by France's own Lumière brothers.
The Frenchman, who worked for National Geographic, captured these snaps of the City of Light almost 100 years ago, showing a somewhat familiar Paris as well as some fantastic fashion from the 20s.
