What is the main value of using a computer to make art?

The greatest, or the most significant, change in art over the past century was collage. It has had an enormous influence, whether it was John Cage, Schwitters or John Heartfield, Picasso and his collaged sculpture, or even the late work of Matisse.

For me, being in a sense a figurative artist, the great disadvantage was that it reduced everything to a small scale because the collage material I used tended to come from magazine pages. Whatever I composed with it ended up more or less on the scale of Life magazine or the Sunday supplements. So I often used collage as studies to initiate paintings.

But now, with computers, once things are scanned in, the computer, each of the elements can be made any size you like. It is possible to do anything at all: changing scale, colour, flipping, cutting and pasting.
