Everyone needs someone saying something like the N word in an official document before they can buy that racism exists. It's not possible that capital follows racial lines (spoiler: it does) and that therefore incentivized products to develop in a particular direction, to appeal to the folks with money? You don't need "overt racism." You don't need a guy twirling his mustache, spouting white supremacist rants.
Do you know anything about film? If you do, then please contribute; if you don't then I would encourage you to actually get educated about the topic involved rather than just knee-jerking your way to validating your own bias.
Using Photoshop as a "Mobile interaction designer + developer" does not an expert in photography technology makes. Doesn't even count actually -- the issues behind film dynamic range have nothing to do with Photoshop. As for the "darkroom experience", well it doesn't mean much. Plenty of photography enthusiasts don't know their chemistry and physics -- just barely enough to develop photographs.
If you have a specific technical comment about how they could easily optimize dynamic range in those crude early films and didn't (because of racism), then tell it.
If you also think that film companies shouldn't had optimize for the main market for a commercial product regardless. Would even a black film company owner optimize for the 20%, less afluent to buy cameras, US market?
So is film racist or not? Do you have any science? Exposure tests? Test prints? Any proof at all? Or just a hatred of the 'man'?
With so much experience, you should have lots of evidence to prove the racism of film.
The simple fact is this, black Hollywood would have screamed about this long before now if there was even a remote chance that film was racist. There would have been academic debates, a long line of evidence and years of discussions among technical and critical circles. Not just some random internet article from a non-qualified source making a claim with no peer-review or any sort of intellectual authority.
We might be bankrupt as a community; yet here you are.
You just need wild, race-based income inequality.
Guess what?
That happened.
