Sports pictures: guest editor - James K. Colton
In July 2010 CPN readers from around the world submitted their sports images to Editor's Choice for review by Sports Illustrated's Photography Editor James K. Colton.
In a multimedia presentation Colton revealed his choice of 36 pictures and talked in detail about his favourite 10 images. He also gave guidance to photographers on what makes a great sports image and what Sports Illustrated, one of the world's leading sports publications, is looking for when it chooses photography. He called the images that CPN readers submitted "dynamic and diverse" - everything from well-lit and stylised portraiture to action shots and photo illustration. He also explained what he calls the basic principles of sports photography: content, composition and colour.
