French towns and landmarks are captured in pioneering colorised images from the 1890s 

  • Images capture France as it was 120 years ago during La Belle Epoch, before it was crippled by two world wars
  • Photographs show Nice and Brittany in the process of transforming into the tourist attractions we know today
  • Paris can be seen during the 1900s world's fair which debuted invetions such as diesel engines and escalators
  • Pictures created using Photchrom process, which involves using dyed limstone tables to colour photographs



These incredible images show what life was like living in France more than 120 years ago in stunning colour. 
From Normandy to Nice and Montpelier to Marseilles, images taken around 1890 show France during La Belle Epoch, an age of huge cultural, scientific and artistic advancement before it was devastated by two world wars.
The pictures were created using the photochrom process, where a series of dyed limestone tablets were used to create a colourised version of a black and white negative image.
The technique, created in Switzerland in the 1880s, was used to produce some of the earliest examples of coloured photographs, and is particularly well-known for its use on postcards.
These incredible images show France in 1890 in detailed colour photographs produced using a technique known as Photochrom. Here, the bourgeois are seen taking to the boardwalk in Trouville, the same boardwalk that inspired some of Monet's paintings around two decades earlier

Notre Dame cathedral in Paris, devoid of the huge crowds of tourists it draws today, is seen in 1890. The stonework on display here is relatively new, having been restored and updated by Eugène Emmanuel Viollet-le-Duc, starting in 1844

Women are seen washing their clothes along a river in Nice in 1890. This period, known retrospectively as La Belle Epoch, saw the coastal city undergo a huge change. The invention of the railway brought a confident aristocratic class here to spend their money and enjoy themselves, establishing Nice's reputation as a premiere tourist destination

Sunseekers wander along the beach in Parame, in Brittany, around 1890. Like Nice, this period saw Parame become a tourist draw, with the Grand Hotel constructed there in 1880, which was a favourite holiday spot of the Grand Dukes of Russia

The German Gate in Metz, constructed in the 13th century, is seen around 1890. While controlled by the French for a large part of its history, Metz was actually under the control of the German Empire around this time, having been handed to the country at the conclusion of the Franco-Prussian war in 1871

Rue de Boigne, in Chambéry, was built around 60 years before this photograph was taken as a tribute to General Benoît de Boigne, a military man and adventurer who was born and died in the city. The street was designed as the cultural and social heart of the city, flanked by arcades filled with expensive tea rooms and cafes
In this photograph taken in the opposite direction the street can be seen lined with cars

Cargo comes and does at the Quay de la Joliette, in Marseilles, around 1890. The port was newly constructed around 1840 to take pressure off the Old Port, which was becoming overwhelmed with the sheer volume of goods arriving. Today, the dock in la Joilette forms part of the largest trading port in France

HOW COLOUR WAS ADDED TO THE PICTURES: THE PHOTOCHROM PROCESS INVENTED 120 YEARS AGO

Invented by a Swiss printer in the 1880s, the Photochrom process began with coating a tablet of lithographic limestone with a light-sensitive emulsion, then exposing it to sunlight under a photo negative for between 10 to 30 minutes in summer or up to several hours in winter.
The emulsion would harden in proportion to the tones of the image and the less-hardened portions would be removed with a solvent, leaving a fixed lithographic image on the stone. 
Following detailed notes on colour made by the original photographer, litho stones would be prepared for each tint to be used in the final color image. Often more than a dozen stones would be needed for a single postcard.
Each tint would then be applied, using separate stones with the appropriate retouched image. When completed, the delicate process produced surprisingly lifelike color with far greater precision than traditional hand-colouring.
Despite the prints looking very similar to colour photographs when the pictures are viewed with a magnifying glass the small dots that make up the ink-based image can be seen. These early Photochrom prints were immensely popular especially because, although colour photography had been developed, it was still rare.
The process was mainly used to print postcards which became particularly popular in the US after the US Congress passed a law in 1898 allowing private companies to print postcards, as opposed to the post office having a monopoly on them.
They were sold at tourist sites and through mail order catalogs to travellers, tourists and photo collectors. The technique was popular around the world and there are hundreds of surviving Photochrom pictures from a range of countries including the US, France and England.
