Getting the most out of an image taken during a sporting event can be a challenge. The biggest problem is the amount of similar hues/tones (especially in football) that overwhelm a picture; muddling the foreground and background. These are the techniques I use to help make the focal points of your shot more interesting, more dominant, and more dynamic (and no, that doesn't mean HDR - ugh, HDR makes Jesus cry).
Software: Adobe Photoshop CS3
