Each individual pixel, everyone of the smallest pictorial units, each 'pictorial atom' can be changed. Since there is no longer an original, there is also no longer any proof for 'truth'. In the final instance, the digital electronic image will make the divide between 'reality' and 'second-hand reality' deeper than ever before, perhaps rendering it insurmountable. In other words, pictures have completely changed their being in the course of time, have been transformed from unique painted works into digital clones. The latter have arisen with incredible rapidity and have multiplied at a similar speed. We are being bombarded by images to an extent unprecedented in human history.
