I just read a review today in the Bangkok Post regarding an exhibition of roughly 20 black and white prints at Playground on SUkhumvit Soi 55 (Soi Thong Lo). It is by one of Thailand's foremost commercial photographers named Chamni Thipmanee.
The review is sort of mixed, but it still sounds interesting and may be worth checking out.
It runs until April 30 and there seems to be a web site for the photogrpaher at
www.thaiphotography.comHave a look.
