Modulating devices research:
Reflectors:
In photography and cinematography, a reflector is an improvised or specialised reflective surface used to redirect light towards a given subject or scene.
Filters:
Filters are mostly made of high quality glass (or resin) and when attached to the front of a lens, are used to block (filter) certain colours or types of light coming into the camera. Some filters (eg ND filters) are designed to reduce the overall light intensity coming into the camera.
Bounce umbrellas:
The bounce umbrella, a parabolic in shape, keeps the light closer to the same distance from the subject. It also forms a light that can be seen from the side of the subject (wrap). While it is less diffused than the shoot thru umbrella, the bounce creates a more even light with the added wrap for cutting contrast.
