Stacey Baker, New York Legs

When Stacey Baker spots a good pair of legs, she has to move quickly. Sometimes she races down the sidewalk to catch the woman before she slips out of sight. Sometimes she sidles up and gently introduces herself. Quickly, she persuades the stranger to pose for her by whipping her iPhone out of her pocket, showing some of the images on her @stace-a-lace Instagram account and explaining that she needs the woman to stand up against a particular wall and raise her arms above her head.
