For filmmaking purposes, controlling how much light comes into the lens is pretty basic. Opening or closing the iris (or aperture) of the camera can control the total amount of light, but what if you want to be more selective? You might need to control light sources individually and that's where a dimmer comes in.
Simply plug whatever light you wish to dim and crank down (or up) on this very handy gadget. Made easily and cheaply with hardware store parts, this little dimmer can handle any light up to 600 watts.
If you're not a filmmaker, this gadget will still handle most of your light controlling needs.
