Striking Red in a Black and White World

Here's a picture that I'm considering for my project, Urban Serendipity. Over the last couple of days, I've been posting images of isolated figures in tunnels, on escalators, and on stairs. I’ve demonstrated that even small and large puddles can create interesting shadows that isolate figures or add an intriguing and sometimes confusing element to the image. This image places the individual in the entrance of an immense office building. On the left, you can see the small security gates giving access to the elevators. The red is coming from a door giving access to another elevator. I like this photograph because of its clean composition and the striking contrast of the almost entirely black and white scene with large red shapes - London, UK.
