Rob Haggart, aka A Photo Editor, does a great job introducing this video of Annie Leibovitz photographing Queen Elizabeth.
What I find interesting in photo shoot videos is not the 11 assistants or the lighting setup but watching the photographer interact with the subject.
As Rob says, "Annie really shows her tenacity in this video when she immediately tries to get the Queen to remove her crown after deciding it doesn't look good in the first shot and not giving up on an original request to shoot the Queen on horseback inside the state apartments."
Simultaneously fascinating and terrifying -- like watching a trapeze artist at work.
