I saw the following clip on You Tube showing a little behind the scenes action of Annie Leibovitz working on an advertising campaign for Louis Vuitton.
It’s very short, but still interesting to see the gear she is using: umbrella with diffuser for light, PocketWizard trigger, fan, speed boat in the background, movie icon (and movie icon’s private beach).
And here’s the shot used in magazines.
Also interesting to note how stickers vanished from the bag in the final image. (You’ll have to watch it again now!)

I’m a fan of Annie. I have her documentary on DVD and very much enjoyed watching her work, especially on the Marie Antoinette shoot.
