To fix this photograph I would do a couple things. First, I would change the backround. For a wedding photoshoot it should look happy and pretty, for example a flower field or a nice building, not a run-down nasty building. I would also change the fact that the bride isn't looking at the camera. Another thing I would do, which is unnessary but might look better, is pose the couple differently. The photographer made the groom more focused on so I would change their positions to distribute the main focus. I do, however, like the candidness of the shot.
A nighthawk is a nocturnal bird, hence the name. Value contrasts create the minute illusions of form in the shining, glossy hair atop the woman’s head, as well as the concavity of the male patrons’ fedoras.
