The Disruptive Library Technology Jester has a link from here (http://dltj.org/article/jpeg2000-survey/) to a survey being carried out by David Lowe, Preservation Librarian at the University of Connecticut. Chapter 3 in the Lesk textbook is on “Images of Pages” and chapter 4 on “Multimedia Storage and Retrieval,” so people who are interested in collections of digital images may want to investigate this. The DLTJ post also has links below to some related posts/discussions of JPEG2000.
I’ve never been much of an image person myself (despite having taken art classes in high school and as an undergrad) and so my understanding of the different image file types is pretty minimal. I think this is probably an area I need to read up on, at least a little bit. Ideally digitized images would be faithful to the original, have a small file size, and bear metadata as part of the file – but I suspect it’s a case of “choose any two of the three”.

Not sure if you knew this but when it comes to digitizing photos, it is best to scan the negatives. In my archival internship this summer, the archivist told me that it was the best way to get the true image of the picture. She said that pictures start to degrade and if they are older and you scan them you tend to not get the full effect of the original picture. I know that may not directly relate to your entry but came to mind when I read it. Just thought I would give you a bit of information.
