Hito Steyerl, In Defense of the Poor Image / Journal / e-flux.
Two relevant views on the usage and (mis)use of poor quality images in film and later online media.

” In For an Imperfect Cinema, by Juan García Espinosa, (Cuba – late 1960s) he argues for an imperfect cinema because, in his words, “perfect cinema—technically and artistically masterful—is almost always reactionary cinema.”

“But, simultaneously, a paradoxical reversal happens. The circulation of poor images creates a circuit, which fulfills the original ambitions of militant and (some) essayistic and experimental cinema—to create an alternative economy of images, an imperfect cinema existing inside as well as beyond and under commercial media streams.”
