Visual balance is considered as one of the important factors in defining the aesthetic quality of visual arts. In this paper, we propose a novel method to obtain visual balance in a layout with dynamic visual elements. We use the idea of a spring-electric graph model and augment it with the concept of color energy from the literature of visual arts. We also present an interesting application of the proposed model in photography assistance. We focus on group photography and utilize social media images along with the proposed spring-electric model for providing a recommendation to the user. The proposed method can provide real-time feedback to the user regarding the arrangement of people, their position, and relative size on the image frame. We conducted qualitative experiments along with user studies to evaluate the proposed method. Experimental results and user studies show the effectiveness of the proposed model in obtaining visual balance and group photography recommendation.
