I'd also guessed they were using a two rather than three colour process.<br /><br />Then I switched back to the video and noticed the end credit to "Claude Friese-Greene the inventor of the Friese-Greene Colour Process".<br /><br />Bingo! Wikipedia confirms my guesses were right; it was an alternating two-colour process.<br /><br />https://en.wikipedia.org/wiki/Claude_Friese-Greene<br /><br />So, essentially they were using black and white film to generate colour.<br /><br />As for those old nitrate films, they're scary indeed. They were dangerous when new, and age-related decomposition makes them even more dangerous and unstable.<br /><br />This video of a reel of nitrate film being burned is particularly interesting:-<br /><br />https://www.youtube.com/watch?v=gEz_a-Akufk<br /><br />(Check out how fiercely it starts burning from around 5:14 onwards...!)Mostrormhttps://www.blogger.com/profile/11124999849533200955noreply@blogger.comtag:blogger.com,1999:blog-987738695581729895.post-5590897356247116832014-02-07T07:15:36.591-08:002014-02-07T07:15:36.591-08:00Oh my.

Exposure to sunlight can destroy the frames, and over time, damp and varying temperature also deteriorates the picture quality and the film reel material itself. This is the reason film archives keep them in media vaults because they’re damp and light free.<br /><a href="http://www.williamsdatamanagement.com/?p=hard-drive-data-recovery-los-angeles" rel="nofollow">Ruby Badcoe</a><br />Rubyhttps://www.blogger.com/profile/16314434089797506245noreply@blogger.com
