Understanding Digital Images: Basic to Intermediate Concepts

Andersen Library.

Confused by the technical jargon of digital imaging? Frustrated by training seminars that assume too much prior knowledge on the part of the student?

This day-long series of presentations guides the participant from the very basics of digital images to intermediate-level concepts, giving them the essential knowledge to embark on further exploration. Sessions cover the basics of digital image files, the mechanics of digitization, intermediate concepts such as colorspace and profiles, and suggestions for setting up computers for imaging work.

Friday, May 27, 9:00 AM - 4:00 PM (Central Time)
Andersen Library, University of Minnesota, Minneapolis
