The warm, natural color grading of 80s and 90s movies shot on film.
Iโd like to point out that none of these movies have anything resembling โnaturalโ color! The โwarm, naturalโ vibe people remember from a lot of โ80s and โ90s movies isnโt some untouched neutral image. Itโs just as crafted a look as any more modern film. Back then, the look and feel was created using the chosen film stock, lenses and filters, lighting, lab timing, and was optimized for the way those movies wouldโve been viewed at the time. (In fact, many of those films would have had digital intermediates.)
How those films look is no more โnaturalโ than the films created now. And those films were all produced using wildly different techniques and technologies.
By the way, of course there is NO SUCH THING as a โnaturalโ image. Itโs all constructed. Itโs similar to philosophy. If you believe itโs pointless and shouldnโt exist, it just means you are then following someone elseโs philosophy without even being aware of it.
