Food literally fuels us. It really gets the people going! I try to use natural light when I take food photographs when I travel. For the simple reason that I do not like to bring a flash or an obnoxious flash box with me. They are cumbersome, heavy, and just not really fun to use when its just me and my backpack.
People get super creative with their food and make it edible art, I LOVE IT. The plating techniques that gives food the visual effect of eating it, is awesome!
