Like masturbation, which everyone does but no one admits to, chimping is rife in sports photography. Chimping is when you check every photo you take on the LCD. While the odd check to make sure your settings and light is good is okay, too much chimping and you’re guaranteed to take your eyes off the field and the action.
And in most sports photography the nature of the beast means that you get no second chances. The moral? Too much chimping will make you go blind.
