See Joe McNally in "Small Flash, Big Donuts"

Joe McNally shows how to blend light with existing light in this behind the scenes video. Join him as he demonstrates Nikon's CLS system at Ralph's Donut shop in Cookeville, TN.

Note from Sean: I can't shake the feeling that this donut shop looks really familiar to me. :-)

B&H carries the Nikon D810 and Nikon Speedlights.
