In 2007 film-maker Errol Morris went to Sevastopol to identify the site of this "first iconic photograph of war". He identified the small valley, shown on a later map as "The Valley of the Shadow of Death", as the place where Fenton had taken his photograph (see right). Two pictures were taken of this area, one with several cannonballs on the road, the other with an empty road. Hitherto opinions differed concerning which one was taken first but Morris spotted evidence that the photo without the cannonballs was taken first. He remains uncertain about why balls were moved onto the road in the second picture—perhaps, he notes, Fenton probably deliberately placed them there to enhance the image. The alternative is that soldiers were gathering up cannonballs for reuse and they threw down balls higher up the hill onto the road and ditch for collection later. Other art historians, such as Nigel Spivey of Cambridge University, identify the images as from the nearby Woronzoff Road. In June 1855 illustrator and war correspondent William Simpson produced a watercolour of the Woronzoff Road, but looking downhill, which has cannonballs similarly placed to those shown by Fenton; Simpson's publisher too used the title "The Valley of the Shadow of Death". This is the location accepted by the local tour guides.
