Next stop on the tour of Dunedin, seen through early colour film is Tunnel Beach. The hidden beach is an amazingly popular spot for tourists. For this photo I used a preset based on the process called Autochrome. The early colour photography process of Autochrome was introduced by the Lumière brothers Auguste and Louis of France in 1907. In this process a colour image is created by combining microscopic layers of dyed potato starch grains on a glass plate.
