One way to be very creative in composing an image is by framing your subject inside another element in the image. You can use architecture, tree branches, windows, tunnels; anything that can isolate your subject or form a frame around it. It's a clever way to call attention to your subject and make it that much more special.
In this sweet portrait of a brother handing his sister a bouquet of daisies, the siblings are framed by the giant oak tree in the background and wildflowers in the foreground. The pair are also positioned on the two-thirds line.
In this image, my lovely subject is framed by the arches of the breezeway.
This image follows at least 4 compositional rules; Patterns, Leading lines, Rule of thirds, and Framing. The Georgian Terrace is framed by the AT&T Midtown building.
