In order to develop a lighting vision, one must understand that all light behaves fundamentally in the same way. Sunlight is the same as the light emitted from a flash, which, in turn, is the same as video light. The way it works is that light is a form of energy called electromagnetic radiation. This energy travels in groups called photons. These photons carry an electromagnetic field around them that fluctuates with speed. The faster the electromagnetic field fluctuates, the more energy each photon has. Although we cannot see the actual electromagnetic field at work, we can see the effect of the speed of the wave fluctuation ...
