We went to the NPG (National Portrait Gallery) for the Taylor Wessing Photography Prize, but stayed for some extra bits as well.
The images are always interesting and many are definitely worth close inspection - the winners for Taylor Wessing 2011 are here - and some really captured my imagination. It's capturing the sitter that is so interesting, though where images come from a series I do wish there was a bit more information about the sitter.
Elsewhere in the NPG, the big paying exhibition is on The First Actresses, covering early actresses of the British stage: we didn't really haev time for that one, but did see the side-room exhibition (free) The Actress Now which was great. (Even though I did get cross at the innacuracy on the signage for Samantha Morton which said she did television work Band of Gold and Under the Skin --- NO, Under the Skin was a FILM).
