I've had to do some research when a groom has changed occupations and I needed to prove that the person I originally put on my tree as a salesman and member of a manufacturing metal working company up in Aberdeen changed his occupation later in life and became a photographer in Sunderland.
The link between the company that made signs for the railway and also manufactured its own miners lamp was that the first photographs consisted of a metal base and the salesman ancestor had experience of working with metal.
"Louis Daguerre developed the metal based daguerreotype process, the first publicly announced and commercially viable photographic process. The daguerreotype required only minutes of exposure in the camera, and produced clear, finely detailed results. The details were introduced to the world in 1839, a date generally accepted as the birth year of practical photography."
