The Canyoneers 1 p.m., Oct. 22
San Francisco-based photographer Chris McCaw speaks about his project, begun in 2003, in which he creates images by allowing the sun to burn its path onto a paper negative during a long exposure, using the camera as a tool for both creation and destruction. The lecture will be followed by a signing of McCaw's most recent book, Sunburn. Info: email@example.com or 619-238-7559 x235.
