[1][2] In 1923, as Jeanne Devos's health deteriorated, Abbé Joseph Lamps transported her to Corsica, where he initiated her into the world of photography, specifically focusing on autochromes and stereoscopy.
Beginning in 1936, she extensively explored Flanders, capturing a rich array of photographs that documented the region's rural and traditional lifestyles, occupations, cultural beliefs, and festive celebrations.
On September 7, 1944, Abbé Lamps and Jeanne Devos were in Bissezeele during the village's liberation, where they recorded over 150 photographs of the 5th Canadian Infantry Brigade as it moved through the area.
This initiative was innovative, as she became the first to provide a comprehensive photographic account of the wedding day, including ceremonies held in the church, an approach that was met with disapproval from religious authorities at that time.
[2][11] On June 10, 2022, a documentary on her life entitled "Les images de Mademoiselle Devos", directed by Anne Bruneau, was shown at the Studio National des Arts Contemporains[12] in Tourcoing.
