When a camera takes in an image, it is objective and records what comes through its lens, without bias, not giving preference to one piece of information over another. The brown book sitting on the shelf is as important to the camera as the red fingernail raised toward the sky.
When the brain takes in an image, it receives 400,000,000,000 bits of information each second, but only processes 2,000 of those bits because the brain has a network of neurons that has been trained to use associations, both of objections and of familiarity, to sort information into quickly usable portions of fuel for decision making.
When watching a movie, is the focus on the streetlight in the background or the exploding truck in the foreground? The camera makes no separation between one bit of light and another, but the brain does.
