Course schedule

CS 178 - Digital Photography
Spring Quarter, 2013
Marc Levoy
Handout #2

Here is the current version of the course schedule. It is also available online at, and will be continuously updated as changes are made. In particular, lecture titles and assignment names will become clickable shortly after a lecture is given or an assignment made. Readings should be completed before the date on which they appear in the schedule, except for the first week. "London" and "Peterson" refer to your textbooks; "http" readings are online; all other readings are from your course reader. For London, the 11th edition is assumed. Unfortunately, some material present in the 10th edition was omitted from the 11th edition. This material, designated as "10e" in the schedule, will therefore be considered optional reading. It will also be covered in class.
