The single easiest thing that you can do to improve your photography is to fill the frame.
By filling the frame with your subject, you put the emphasis completely on it. There’s nothing else to distract your viewer. Filling the frame removes everything that’s not essential to your image.
When you fill the frame, you clean up the clutter and the result is an image that is striking, and has impact and drama.
In the video below, photographer David Bergman shows us how filling the frame can vastly improve our photos.
