I have a shitload of shots like this from last year's petit le mans... lol I had to kind of teach myself the technique on the fly. All of a sudden I understood why when you look through the lens using the eyepiece there's crosshairs there. Here's a couple (they've been edited in photoshop, obviously)... I don't think I did too badly considering my subjects were moving upwards of 160mph, and I was shooting using my crappy FinePix A205




^^old one.. dirty ass show car, but a cool pic I think

I'll put up more if you guys want em when I get home
