Hi, I am going to London this Saturday (will be free to sightsee from about 9-5). I know I read about an exhibition recently that I'd really like to see, but stupidly didn't make a note of what it was and now I can't find anything that rings a bell on any what's on sites. I feel like it would probably have been photography and possibly something to do with architecture or costume, and maybe only on for the first half of the year.
In the absence of any clues to what my original idea was, I'm currently thinking of going to the 80s photography exhibition at the Tate Britain and the Peter Mitchell exhibition of photos of Leeds (a place I used to know quite well) at the Photographers' Gallery in Soho.
Does anyone who lives/works/sightsees in London have (a) any suggestions for what the lost idea might have been or (b) any other recommendations for something to see or do, preferably free or inexpensive?
