As staff photographer at SRI, I've gotten to shoot plenty of portraits, from formal corporate sittings for execs and new hires to a more casual series titled 'A Community of Innovation'. Most of these are from the latter, and are featured on large graphics installed at SRI's different offices along with quotes from the pictured researchers. I'm comfortable in studio or on-site, have attended workshops by Joe McNally and Rick Friedman, and have read every article on The Strobist. Twice.
