Open Format Cropping

Open format cropping is a photography technique that focuses on details of the subject, for example texture or shape. Photographers often crop out unnecessary parts of the photo to ensure that they get the most interesting details possible.

This photo by Torika is a great example of open format cropping. Because the viewer can't see most of the meerkats, it creates mystery as to what is beyond the frame, and leaves them with many questions. Also, the background is out of focus, making the meerkats stand out even more.
