The camera obscura is appearing in a book arts exhibit called "Sense and Sensuality," a national juried show which I believe will also feature work by recent L&TM5K contributer fingerstothebone.
Here are the dates:
June 27 - August 4, Thurs - Sat 12 to 6 p.m.
Artist Reception: Friday, July 13, 6 - 9 p.m.
NE Sandy and 23rd in beautiful Inner East, Portland
And here's an example of the kind of thing you might see if you gazed into the camera obscura.
