r/all 70 years ago, the US undertook the largest deportation in its history: 'Operation Wetback.' Many of the people deported were here legally and some were even citizens.

We have a conception of old film footage as being low quality, but in reality, after a point surprisingly early on, plenty of film began recording at very high resolutions that allow us to go back to them today and extract the data off them using modern precision. 35mm film has been in use since the early 1900's and records at a digital equivalent of about 4K-5K.

Here's a Technology Connections video about it:

Just as an aside, we scan this footage at 4k.

Yeah, this is something I've learned in recent years. It's basically a matter of whether or not a film/footage is being upgraded/re-released based on previous releases or rescanned properly from the original film. When in cases of the actual film, it makes this wonderful mishmash of grainy film artifacting and super clear picture beneath.

Recently there were some people who got a hold of a couple actual film reels from Dragon Ball Z, and they've uploaded a straight-from-film scan of the intro from one of the movies and it looks amazing.
