Fredrick Scott Archer (1813-1857) invented the photographic wet-collodion process in the 19th century. A mixture of a bromide, iodide or chloride dissolved in collodion was poured onto a tintype or clean glass plate for a few seconds. Once this reaction was complete, then moved on to expose, develop, fix and finally rinse it. As the glass plate is getting wet throughout the whole processes from adding the chemicals to taking the picture, this process is also known as “Wet Plate Collodion Photography”.
The University Library will be hosting an exhibition “Hong Kong Through the Lens of John Thomson” from 15 November 2018 to 28 February 2019. The majority of his photographic work was produced using what is known as the “wet-collodion” process. This workshop will introduce the principles of traditional photography and the production process of the Wet Plate Collodion Photography such as lens operations, choice of plates, mixing of chemicals, etc.
