Representations of the world can seem more realistic than the real thing. By developing an image which can enhance memories, challenge ideas, or reinforce stereotypes, we can also change 'real' life. The camera has proved a remarkably powerful technology for recording interesting and sometimes disturbing images. From railways to war and foreign parts, the exotic has become familiar through photography. The remarkable photographic collections of the National Museum of Photography, Film & Television include the archive of the Daily Herald newspaper which began in 1912 and ran until the mid-1960's. The National Railway Museum and the Science Museum also have powerful photographic collections, interesting both for their subjects and treatments. Whether through travel in the picture album or through the railway poster, we can all enjoy a sort of virtual travel across space and time.
