BEFORE THE IPHONE MADE SELFIES COMMONPLACE, I shot a selfie without knowing it. All I'll say is that the photograph was made in New York and has not been composited in Photoshop. It is a single image with no post-processing except for minimal exposure adjustment and sharpening. Full marks to anyone who can figure out, or guess correctly, how I did it.

Nikon D90, Nikkor 18-200mm AF at 18mm, 1/80 at f/3.5, ISO 200. Click on the image to view in lightbox.
