Photo processing is no longer in demand as a career because digital technology has largely replaced the use of film.
Explanation:
Careers like photo processing are no longer in high demand because technology has advanced and now photos being taken are largely digital format and this had done away with a lot of the need to process photos manually using chemical agents. The principal means of processing photos using a gelatin-silver process required soaking the photo in a series of different baths like the developer bath, the stop bath, and the fixer bath. Gelatin silver printing has been the most common process for photographers to develop black and white photographs since the 1890s when photography started to become more widespread and commonplace. Digital photography has revolutionized the way that the average person takes photographs and there is no longer much demand at all for cameras that use old-fashioned film.
