I don't think that finished movies come from raw film, they come from
recording the images and sounds of actors and scenery. The raw film is
actually the public medium between one rich private experience and another.
What personal awareness lacks in sub-personal fidelity to appearing
gorillas it makes up for a thousand fold in fidelity to the totality of
experienced anthropology. It's odd to me that the worldview which expects
sense to be a solipsistic simulation within the brain is surprised that the
brain makes mistakes that seem real rather than that it can compose high
fidelity reality out of senseless mistakes.
