I found a great set of photos on flickr taken by Max Westby (Max xx). I don't think he is doing backwards beekeeping but there are lots of great shots of wild swarms and hives.
One highlight for me is a group of pictures of these eccentric hives maintained by an 82 year old man.
This is a wild hive that formed in only 3 weeks between the bathroom window and shutters of a vacation home in Lyon.
See Max xx's whole set on flickr.
