The Photoflex LiteDisc 32" White/Gold Reflector's purpose is to reflect light. That was pretty obvious, right?
The light source can be artificial such as flash lighting or natural - the sun. The Photoflex LiteDisc 32" White/Gold Reflector is useful in removing dark shadows from your subject such as in outdoor portrait pictures. It can add a nice fill light when it is needed or desired.
The LiteDisc twist-folds into a small, round, zippered case for storage. It is light and compact for easy portability.
I don't find myself using my Photoflex LiteDisc 32" White/Gold Reflector very often. On a bright sunny day, the reflected light is too bright - my human subjects squint too much. Also, use of the reflector typically requires an assistant or a holder. I often have neither of these available.
