British-born, New York-based photographer Alex John Beck’s photography series is a study on facial symmetry entitled 'Both Sides Of'.
To find out if it’s true that the most attractive faces are symmetrical, he took the left side of each subject’s face and replicated it mirror-image onto the right side. He went on to do the same with the right side of each subject’s face.
The two photographs were then placed side by side for comparison.
