Fantastic pictures! I wonder what TLR camera the girl is holding @1.34... an early Seagull model maybe?? Ah... where's my "Cameras of China" book is when I need?
I also like the "ghost" on the bottom left of the picture @2.51.
While at Carl's doing the collodion workshop early this year he showed me an amazing book with pictures of 19th century China's photography, unfortunately I can't remember the name...
