One on Ansel Adams, an absolutely brilliant photographer of California landscapes from the early 20th Century, and another on Wolfgang Sievers, an industrial photographer who took many fantastic photos of Australian industry.
I'm inspired to get out and photograph again. The proliferation of digital photography bothers me. I see hundreds of fantastic photos take by amature artists on the net, but how many of these images will be remembered in 100 years time? How many will still exist?
One big electronic pulse and they're all gone.
