Five types of balance in photography are: Symmetrical, Asymmetrical, Tonal, Color, and Conceptual. Some ways to create balance are geometrically, minimalistly, and cropping. What is great about this group is that we can interpret the prompts literally or figuratively.  For my photo, I tried to achieve tonal balance as well as balancing the stones. Have fun with the prompt. I look forward to seeing all the great photos you come up with!
