Photography was invented by Niepce and improved upon by Daguerre who invented the daguerreotype in 1839. The daguerrotypes were mostly studio photos for the rich, the later ambrotype using glass plates was cheaper and studio photos were accessible to even modest families.. In 1888 the Kodak camera made photography the first art really accesible to all.
Originally all photos were in black and white, the colour photo becoming popular only in the 1960s. The black and white photo is a precious aid in decoration, immediately giving for example an Art Deco feel to a room or a vintage atmosphere with snaps of the 1950s to 1970s. It is also a collectible item on different themes or by the choice of a famous photographer.
