•In the past: images
and text made in same way, by
hand (e.g., Medieval manuscripts)
•Changed in 1450s with
Gutenberg’s printing
press
•Why no similar
technology for images? Text
already an abstract, discrete method of
encoding meaning (paperback has same
content as original manuscript)
•In general, no way to
abstractly encode images
until computer graphics. Print of a painting
not equivalent in content to original…
•Now have abstract
(text- and numbers-based)
representation of images—images produced
are different views of that same data
