Negative space can give your photograph an entirely different atmosphere than the other photograph of the same subject. The absence of content does not mean the absence of interest. In fact, negative space often adds interest as it can place a stronger emphasis on the subject and it can evoke emotions effectively. Negative space brings clarity to a photograph but it also leaves a nice area that can be filled with text or boxes without taking away from the object in focus.
