All images made with the Fujifilm X10 Some have a little fill flash from the Fujifilm EF-20 flash Editing in Lightroom 5.2.
In this video on flash photography, Gary Fong shows how to quickly and easily "fool" the custom white balance of your camera so that it "colors the world" in the opposite color. Then, by using a Gary Fong color gel tab (or color dome) on a Lightsphere, the color on the subject is corrected out to a neutral tone! This enables you to create spectacular effects not possible through Photoshop or other post production software.

Gary is using a Canon Digital Rebel (not sure the exact model) for this demo, but the technique would work for any camera that allows custom white balance settings. To make the background very cold substitute an amber-colored insert or dome in place of the blue one that Gary used.
