I came across a reference to a new book ‘Digital Images for the Information Professional’, which looks interesting, although I haven’t got a copy myself so I can’t vouch for it.
It’s written by Melissa Terras from University College London, and covers: The history of digital images; Digital image fundamentals; Image file formats; Digital images and memory institutions; Personal digital image collections; Image metadata; and Current issues in digital imaging.
