On July 16, from 6pm to 7pm, there will be a talk on "Old techniques being used today". Text from the Carnegie Museum of Art website:
Early Photography: New Uses for Old Techniques
Thurs., Jul. 16, 6:00–7:00 p.m.
CMA Theater
Daguerreotypes, tintypes, and ambrotypes—what are they, and how did they evolve? Learn about some the earliest photographic processes and the way they’re used today in this discussion with Mark Johnson, past president of the Daguerreian Society; John Fobes, artist and ambrotype specialist; and Tom Persinger, photographer, Director of F295, and organizer of the F295 Symposium on 21st Century Photography. After the lecture, look at examples of these classic techniques in the exhibition Digital to Daguerreotype: Photographs of People.

I plan on going, and will probably get there earlier in the day so I can go through the exhibit first. The Carnegie website is www.cmoa.org
