Think of Your Composition
Level your crystal ball with the subject you’re photographing, as a centered subject in the crystal ball will result in lesser distortion. Try to get as close to your subject as possible. The closer you are to your subject, the bigger it will appear in the crystal ball. Whether you’ve positioned the ball on a flat surface, a crevice, or even if you’re holding it, ensure that the crystal ball will not fall.
When experimenting with crystal ball photography, ensure that the light coming through the refracting object is strong. If your subject is poorly lit, you may see unwanted reflections from brighter lights in the vicinity appearing in the ball.
