Photographs are able to make realities, so before photography became financially available, companies like travel agencies could not promote their holidays through photographs as a form of visual proof of where the tourists were about to visit, instead hand drawn images were used. Not only was photography financially unavailable for advertisement companies but it also took a while for them to see the benefits and qualities photographs could hold. In 1920 15% of illustrated advertisements employed photographs, and by 1930 almost 80% had. The idea of a photograph showing a clear understandable image became of interest.
An example of this is the travel agency Thomas Cook, who persisted hand drawn illustrations, brochures and posters well into the 1950’s. However in the early 20th century tourists were beginning to become reliant upon photographs or postcards from a professional. However some felt that instead of these photographs showing realistic images of places they in fact held the opinion or view from the photographer.
But as more advertising companies were using photography it meant competition was increasing. So it was only natural for these companies to all gain access to photographs in order to show their products realistically, the way in which the population were beginning to expect to see them.
