Todd Dominey has published a video on his Youtube channel that dives into the interesting history of a film stock ‘with an origin story unlike any other,’ Kodak Aerochrome.

The 11-minute video, which is part one of a two-part series, walks through why the infrared film was developed by Kodak and what the United States military had to do with its inception. From there, Dominey talks about the film’s significance in pop culture — most notably in the late 1960s and early 70s — as well as the film’s discontinuation announcement in 2009 and the striking Aerochrome works of photographer Richard Mosse.

One of a few albums from the late 1960s and early 1970s that used images captured on Kodak Aerochrome film.

It’s a fantastic watch for those unfamiliar with the discontinued film and still worth a watch for those familiar with it. Dominey says the second video will focus on digitally recreating the aesthetic of Aerochrome film — something that’s been attempted a few times before in the form of presets.
