Photographers Gallery London
This is a amazing place and is one of the high temples of photography in the World. The most impressive and outstanding work I saw, on my last visit, was Richard Mosses amazing "Infrared War Landscapes". These were printed large and a different experience from seeing his work on the web or in a book. A live viewing is strongly recommended.
Some people take the line that he is subverting war photography by his use of infrared film. However, I would rather say he has created a strong and interesting body of work. This is more important than the discussion if he has subverted a style of photography or not.
