I love the structure and sense of togetherness exhibited in this photo.
The Gestalt Law of Closure is used, making the group of dancers appear as one complete unit.
The contrast between the dancers, the lighting illuminating the stage floor, and the black backdrop is visually stimulating. The deep darkness of the back of the stage makes the lines of the bodies sharper and even more dynamic. Also, the shadows on the underside of their limbs versus the highlights enhance the details of their muscles, which adds texture to their skin. Then, the color of their costumes blends with the color of their skin, adding interest to the photo. Given the positioning of the photo, the dancers seem so small on stage, and the distance helps unify them as one.
As a dancer, the lines of their arms and legs, complexity of the lift, and the element of collaboration at work speak to me. Culturally, people view dancers as graceful and view the stage as another different world. It is revered by some. It appeals to us psychologically because we see the dancers up there creating something amazing.
