Here are some images from day 3 of from the workshop in Colorado Springs
Day 3 was Motocross. Some images are made using natural light while some were made using of camera lighting.
Using off camera lighting (ranger studio type lighting with battery pack) I was able to light the rider with the sun behind him.
Big Air (natural light)
Berm Shot using off camera flash.
Same berm as the shot above but a little later in the day, also using off camera flash to light the rider.

Great shots! Great use of lighting! Love Colorado!
Some amazing shots! I love the one of the rider up in the air with the sun behind and the flash filling in the light. Looks like a Red Bull ad to me=)
