This playful collection of photos works well in any gallery format. While any single image in this series could be interesting by itself, an array of dozen or more in a collage display has a unique appeal. Any uniform size would work well. I suggest the 8" x 8" square format with a simple black frame.

Multiple images like these in an identical format are ideal for gallery installations and can accommodate a wide variety of arrangements.

While taking a series of train photos, I noticed my pictures were beginning to take on a particular characteristic. This observation led to an exciting discovery and resulted in my seeing familiar objects in a new way.

These images are typical of the 2:3 image format that's the standard full-frame ratio Nikon and many other cameras use. I typically shoot in this format, cropping and editing later to adjust the final composition.

I noticed in quite a few shots that circles were the primary visual element. This simple observation suggested a square format that emphasizes the circle shape. Editing my images in a square composition added emphasis and interest, and the discovery of the Circle in the Square approach.

I now see circle compositions everywhere that I didn't notice before. This expansion adds a new and exciting viewpoint to my photography, resulting in many opportunities that I may have otherwise overlooked.
