Color. It surrounds us so completely that it’s easy to take it for granted, becoming a sort of visual white noise, unobserved and innocuous. Yet the strategic use of color in a travel photo can really draw in the viewer’s attention. Take the emerald green scarf in the photo above – it’s exactly what caught my eye in Flickr user Mark Fischer’s photo from Sudan. It literally shouts at your eyes against the muted white background of the characters in back. The man’s weathered face, faint smile and white wisps of facial hair further add to the intrigue of this mysterious character.
