Trafalgar Square is a great meeting place, many local attractions nearby, with a good set of steps to chill and soak up the London atmosphere. They have got rid of the majority of pigeons and you can always find people frolicking along the fountains or sipping on a drink and people watching.
Info from wikipedia:
Nelson’s Column is a monument in Trafalgar Square in central London built to commemorate Admiral Horatio Nelson, who died at the Battle of Trafalgar in 1805. The monument was constructed between 1840 and 1843 to a design by William Railton at a cost of £47,000. It is a column of the Corinthian order built from Dartmoor granite. The Craigleith sandstone statue of Nelson is by E. H. Baily and the four bronze lions on the base, added in 1867, were designed by Sir Edwin Landseer.
The pedestal is decorated with four bronze relief panels, each 18 feet square,cast from captured French guns. They depict the Battle of Cape St Vincent, the Battle of the Nile, the Battle of Copenhagen and the Death of Nelson at Trafalgar. The sculptors were Musgrave Watson, William F Woodington, John Ternouth and John Edward Carew respectively.
A traditional silhouette, where the light source is very strong and directly behind, would black out the foreground element however I wanted to maintain some detail. With careful exposure, I was lucky on this day as the sky was quite clear of clouds and very blue. I followed the shadow of the column along the ground until I was standing on the shadow of his head. This set the sun directly in front of him. As I walked up and down the shadow line taking different compositions, I was spotted doing this and a couple of people followed me. I helped them get a decent photo too.
