Here is a fun little shot I made of two frogs in a pond covered in duckweed. The basic theme here is a repetition of the main elements within the image. The two frogs visually play off of one another and become a visual echo of each other. It’s important in a composition like this to make sure both frogs have equal weight within the shot. You don’t want either frog to become visually dominant or the main focal point of the image. The comparison of the two is the focal point. By keeping them equal in visual weight we emphasize and celebrate the symmetry between the two. Additionally, the beautiful S-curve in the negative space of the image adds much to this composition, helping to gracefully tie the two frogs together.
To the viewer this symmetry is visually interesting. They get pulled into the image, enjoying the similarities between the two frogs, or perhaps looking for the subtle differences between the two. Either way, they are engaged and a participant in the image.
