A couple of weeks ago I wrote a post on dating photographs based on photographic process and contextual clues. If this topic interest you, you may want to visit the Stephen A. Schwarzman Building or two classes on dating and preserving photographs. This Friday, I will be teaching a class called Clues from Family Photographs and next week, Tuesday Erin Murphy, the Associate Conservator for Photographs and Paper, will be offering a class called Caring for Family Photographs. Both of these classes will be held at 3:15-4:30 in the South Court class rooms.
