The 'eye' makes many more adjustments. If you have ever taken a photo
of a sunset you will realise that the camera tends to make the image
very red. Sadly the 'eye' (meaning the brain) changes the perceived
tone of the image to filter out excessive redness; this way we miss
many beautiful sights that only the camera can record.
On other occasions when there is so much colour contrast in the sky
that the 'eye' is unable to adjust, we see the sky as a multicoloured
image - sometimes more varied than a camera has the ability to
capture.

This phenomenon can be most easily seen when a camera is taken from a
room lit with an incandescent bulb to the outside where the sun is the
only light. The inside shits tend to be very yellow or with a slight
redish, unless a flash is used. An industry has developed to sell
various filters to mask out these inconsistencies, and they do a
reverse job of the adjustment done by the 'eye'; either a daylight
filter for outside to tone down blueness or one to adjust for none
flash images. Mush of the same effects can be achieved by photoshop.
