Are You a Chimper Too?
"Chimping" means reviewing images on the Monitor after
each shot. I guess people think you look like a monkey if
you review each image. Well, I do it anyway! Sometimes I
even make monkey noises when I'm chimping my images.
Try saying, "Oo, Oo, Oo, Ah, Ah, Ah" real fast when
you're looking at an image and are happy with it. That's
chimping with style, and why the word was invented.
