Scentography is the technique of creating and storing odor by artificially recreating a smell using chemical and electronic means.
[1][2] In 2013, Amy Radcliffe, a Master's student in the Textile Futures department of Central Saint Martins, London introduced a prototype of a desktop device to record aromas.
For the project, she drew on headspace technology pioneered in the 1980s by Roman Kaiser to capture smells in the air around certain objects.
[3] Called the Madeleine, after the Marcel Proust episode from Remembrance of Things Past, the device is a working prototype of a new kind of camera to record smell.
In the scenario developed for the prototype, the Madeleine would be taken for local lab processing in a similar way to conventional photographic film.
