I have cleaned & enhanced for you the oldest verified photograph of London, taken 185 years ago, in September 1839. This is a daguerreotype photograph, taken at Trafalgar Square, looking past the equestrian statue of King Charles into Whitehall and Parliament Street beyond. The photographer was Monsieur de St Croix, who had travelled to London from Paris to promote the newfangled photographic process patented by Louis Daguerre 3 months previously. This image pushes back the photographic record of London to its very beginning and - if you look closely - you can see the ghostly blur of Londoners and the stage-coach traffic, lost to the daguerreotype's long exposure.
