People, still to this day, use both Digital and Film Cameras, and use all formats for travel photography (Large format, Medium format, 35mm). Digital cameras have certainly made taking travel photographs alot more easier and accessible, and much more readily stored and used. Compact Digital cameras have allowed tourists and photographers alike to capture quick snap shots of foreign cities, countrysides, buildings, landscapes etc. Also these cameras are easily stored and able to be carried around in pockets, bags etc.
Film still has its place, even with the large influx of the digital market, Professional and amatuer users alike still use medium and large format cameras to capture their relevant subject matter, as film is still readily made and produced for these format of cameras.
35mm and compact make the ease of travelling with cameras easier, as large and medium format can be quite bulky to carry around.
