I've seen many a dance photograph in my time, but this one... this one stopped me in my tracks. I have absolutely no idea who took this photograph or who the subjects are, but it's one of the best tango shots I've ever seen. Amazing lines. Amazing frame. Amazing contrast.

Lines: All vertical, save one. Their faces, their lips sit at a perfect vertical 180° above one another, the angle of her leg at 45° of the bottom right corner.

Frame: Shooting slightly to the right of the subjects, the photographer emphasizes the sheer importance of the vertical. Though her leg extends to the right, the energy is not away, but inward and upward. Her body may be bent, but she reaches up. The only piece in the photo not moving either in or up are her locks of hair and drape of her dress.

Contrast: His shadowed face, her pale skin, the white leather of his shoe, her stockinged leg. Remove the hat, remove the suspenders, remove the long hair and you have a totally different photograph.

While obviously in a studio, the two in the photo show the beauty of this art form in a fascinatingly pedestrian way. Chances are neither have been through the rigors of classical ballet, but grew to understand and work their bodies on their own, to a point where movement and eye contact are the only necessary communication devices. Every bone, every muscle is engaged in that one second of that one motion - appearing passionate and almost delicate, however requiring the utmost strength and control.
