We stumbled across this image by Austin Mann, a PocketWizard user.
We went out to Cameron Park this weekend to go mountain biking and I decided to to take some of my gear out to shoot a bit. This is my former room mate and friend Jonathan. To light him, I used a Canon 580EX on screen right, with a softbox umbrella mounted on a super compact manfrotto stand fired by a PocketWizard. On screen left, about 20 feet behind Jonathan, I have another 580EX II, on zoom at 105mm, mounted on another manfrotto stand, fired by a PocketWizard. Shot this with the 24-105.
