The use of reflectors in photography is just a way of taking advantage of the existent light, and bounce it to different places in your image. This can be done with virtually any surface that reflects light, like a wall, a mirror, cardboard, styrofoam, aluminum foil, etc. Dedicated photography reflectors come in many different colors, shapes and sizes. Silver, gold, white, and sometimes mixes of these three colors commonly know as zebra reflectors are the most common colors. There are also 5-in-1 reflectors that include a black surface to absorb light, and a translucent surface to soften light.
