I think I disagree on the point about the "medium is the message" framing. I dont think the camera quality has much to do with it, instead the visual qualities arise from the lack of a need to show that critical view, as the blank optimism overshadowed the less savory views by a mile. I think we have lost the capacity to view these process neutrally, independently of the medium used to record them.
I remember watching a hungarian film called On body and soul, which takes place in a meat processing facility. The footage of the meat processing is beautiful, eerily so, and it is really jaunting when you realize the only images of slaughterhouses you have seen is grainy handycam footage filmed for ideological purposes. The medium is always important, but always subservient to the gaze.
I found the video eons ago, it still has so few views and I am so happy to have brought it to light to such a receptive crowd.
