It is rare that a photograph can make me sick from vertigo.  But Peter MacDiarmid of Getty images has succeeded where no one has before – yikes!  He accomplishes just that – shades of Alfred Hitchcock.  His dramatic image shows observers watching last week’s 35th running of the London Marathon as the runners crossed the London Bridge, from the glass floor of the observation deck.  I cannot look at this picture without feeling the need to hold onto the security of my seat and feel an overwhelming desire to find a parachute. I think that this raises is a very significant point about photographs.  When we look at a photograph, if it is a good one, our eye can be tricked and our brains forget that it is a two dimensional object before our eyes and instead transform us into a very real three dimensional world.

While such images create a physical uneasiness, they are a welcome respite from the more gruesome news images of week, which typically makes me sick in other ways.
