Professionals use light bouncing tools to assist them in working with studio flash lighting. The umbrellas look much like a domestic rain umbrella. They come in a variety of colours such as white silver gold and can be "shoot through" & "reflective"
Reflectors do as the name suggests = the reflector. AKA bounce light from a light source such as the sun or a flash. Use them to add white silver or gold for example to your subject.
