A round peg in a square…
You find beautiful, symmetrical, round flower. The first thing you might try as a photographer is to get the camera parallel – so all the petal edges are in focus. And get all of the flower in the frame. But where to put it in the frame?
Centered in the frame – like the shot on the left – always is the least interesting and least dynamic spot in a photograph. Nothing wrong with it, but it doesn’t say that much. You can try to fix it by putting the flower to the side, or cutting down on the symmetrical open space and cropping to a square, or crop to a 4:3 aspect ratio and push the flower off center. Roundness is a bit of a curse in a square or rectangular frame.
Why not try something different? Drop down and make an image from a lower angle and get in close and crop the flower in the frame, like the image on the left. Now the flower center dominates the frame and the the petals cut across the frame on a diagonal.
Both of these compositions have a place. In the right context, for instance as an image with text in the open spaces, the first one could be really useful. I prefer the second or maybe the alternative composition in the last post as an images on their own.
