The whole shot is metered to the studio lights. Then by dragging the shutter(very slow shutter shutter speed) it allows some of the ambient light to capture in the image, giving it the slight orange cast.
It is the same thing as slow or rear curtain sync.
I'm at work and our coffee looks NOTHING like that! I want one!
Great shot. Looks delicious.
Do you do a lot of food work? Ever work with a food stylist? Reason I ask is one of my good friends from cheffie school became a food stylist, he does all right for himself making food look beautiful.
