In this video, Daniel Norton of Adorama takes you into his studio, showing you how to set up for three different lighting scenarios, with the ability to change from one to another at the flip of a switch. This is great for if you have extremely limited time with models or actors and need alternate looks or options between them.
Norton uses zones on his radio trigger to control different lighting scenarios. You'd need a lot of gear to pull something like this off, but in a time crunch it appears to be very effective. Norton shows his entire setup, with notes that cover where each fixture is placed, and how lights are set to create the different looks. He uses PocketWizards, controlling the different zones, to select his different setups. The other trick is to use a light meter to make each setup at the same exposure, and then if you have this option on your trigger, you can use a "cycle" function to capture each zone.
This is originally inspired from the work of Alexis Cuarezma, whose portrait photography work has been covered here on Fstoppers before, as well as in his own behind-the-scenes videos, which I've included below.
What do you think? Is this practical or not? Being able to have gear to create all of these looks is made possible by rental companies with decent rates, but has anyone ran into situations where they needed to do this, even for just two different looks?
