Physics shows us that light is ambiguous and paradoxical, possessing the qualities of both particles and waves. Light's multidimensionality can reveal any subject's many diverse realities, which may be as fleeting as light itself. Developing an awareness and knowledge of natural light is the first step toward the discerning use of its substitute: artificial light. Basic lighting methods are front light, side light, high side light, low side light, top light, back light and under light. Reflector cards are used to reflect or bounce light into shadow areas to help illuminate details. A snoot is a tube that is attached to the front of the light for the purpose of narrowing its beam in order to highlight specific areas. Keep in mind that the camera, lens, software, and paper have but a single purpose: to capture and present light. The two types of studio strobes are monolights and power packs paired with heads.
