if you are looking for something to do over the weekend and you love photography, then pop down to somerset house and see photo london; its your chance to see photographs from all the early great photographers to contemporary now. its a big sprawling exhibition, spread over several wings of the building and levels, plus an added addition in the courtyard. think frieze art, but of photography. i didnt manage to see everything – its a good idea to take a plan with you, and tick off where you have been, cos you can easily get lost. you must see the Don McCullin gallery on the mezzanine level, the finsbury park photos are amazing. book into one of the many talks with the participating photographers – I managed the Alec Soth interview, which was very interesting. its quite pricey, but then when do you get to see so many varied photos in one swoop.
