How would that work? Take a picture of the picture and hash it? Wouldn't that just make the picture you took the source of entropy not the physical one?

You might have something in the image that you could interpret as 1s and 0s. Say, heights of trees in a line. If the next one is bigger, 1, if it's smaller, 0, etc.

If you can reliably produce the same hash from the painting over and over again[1], you can use the painting as the source, and throw away the picture.

What a bummer we can’t do this with the computer encoding of a long but memorable phrase. Ah, were that the tech existed!
