The British Horse Guards were a must-see when we were in London. I captured this shot when the backdoor of the Horse Guard stall was shut creating the black background I wanted. I used Photoshop to create the final effect. The Blues and Royals (Royal Horse Guards and 1st Dragoons) (RHG/D) is a cavalry regiment of the British Army, part of the Household Cavalry. The Colonel-in-Chief is Queen Elizabeth II and the Colonel of the Regiment is Anne, Princess Royal. It is the second most senior regiment in the British Army.
