I saw it recently and was impressed by her pictures and the exhibit itself, but I've haven't got any books or knowledge of her or the photographs beyond being vaguely aware of the work she did, so perhaps I was always going to be a little more impressed than those more conversant with her work and life story.
Having seen the exhibit I'd have been quite keen to go along to the curator talk, I've been in the past and they can be informative and engaging events, but I'm away and won't be able to make it even if I could get a ticket.
