In the normal course of the day, the typical viewpoint for a human is about 4.5′ off the ground. Standing height, sitting in car, sitting on a chair or stool, and looking left and right, up and down at that height. We see so much of the world this way it’s commonplace. Nothing new.
Just choosing a different angle, height, and engaging your subject from that viewpoint will add a tremendous amount of visual interest on its own. It creates interest by breaking their normal viewpoint and giving them something different. The path less traveled.
To create a much more dynamic image, change the viewpoint. Use a view that is uncommon and not normally seen. Lay on the floor, stand on a ladder, use a dutch tilt, shoot from outside in, from above, from below, through objects in the foreground. Anything different will add some additional interest to your images and give the viewer a fresh viewpoint. If all the other components of the image are done well, it will dramatically improve the overall image and add additional interest for the viewer.
