Little seems to be known of Buron; he maintained a business as an optician and engineer on the rue des Trois-Pavillons, Paris. In the early 1840s, portraiture was of a very low quality, given the lenses available which were more suited to landscape photography than portraiture; the lenses needed to be faster and with less distortion for a close subject.
In the spring of 1840, the Société d'Encouragement pour l'Industrie Nationale, announced a competition to encourage improvements in the photographic lenses. Among the award winners was Buron, who received a bronze medal for his ingenious portable camera and darkroon, all contained in a single box, weighing approximately 8 1/4 pounds. Two lenses could be used with this camera: one for portraiture and one for landscape. See Gernsheim p. 117.
This pamphlet is a manual for making Daguerreotypes; the engraved plate illustrates Buron's portable camera / darkroom.
