Leopards Fighting, South Africa

It’s the feeling of motion that makes this photograph of leopards wrestling so successful. Some parts of the cats’ bodies, like the claws and ears, are perfectly sharp. But it is the blurred limbs that grab us and indicate which powerful muscles are working to propel the animal. Photographer Richard du Toit has chosen the perfect shutter speed to showcase the action. —Annie Griffiths

Photo Tip: Although we are tempted to use a very fast shutter speed when photographing wildlife behavior, slowing things down may lead to a more compelling image. The goal is not always a perfectly sharp image.
