Overpowering the sun.

This was a concept that took me for freaking ever to grasp. But what it really means is you kill the ambient, shoot a flash at really high wattage, and shoot a small fstop. Make sense? Okay, no, but what it really is is to darken the overall scene. Here is a good example, if I had shot this with a speed light, there would be a ton of white in the background from the sun, well not that I was able to shoot at f10, the sky was darker, now Kelli here was black. But with a alienbees ABR800 from the left side, I was able to fill her in giving a harsh contrast between the subject and background.

So basically you are killing the abient and filling in with flash, one of my favorite styles.
