The history of photographic studios and photography dates back to the 1840s with the invention of processes for recording camera pictures, by Henry Fox Talbot and Louis Daguerre.
The first use of a "flash" dates back to 1839 when Levett Landon Boscawen Ibbetson used limelight to photograph very small objects.
Photographic studios started using flashes in 1840 and in 1864 the next technological breakthrough, magnesium wire, became the new artificial light source.
Flash powder was the first means of artificial lighting that allowed to produce sufficient brightness to capture the action of the film.
With the introduction of calotypes the production of negatives enabled the photographers to print as many copies as customer required, hence strengthening the very base for the studios.
