Here Bradley Thomas is measuring the light beam to see how much area the light rays expand and the intensity of them using the inverse square law.
Inverse square law:
Light leaving a surface will radiate in all directions.
Square law describes the area of a beam at fixed distance. (light quadruples as it goes out)
Reverse square law describes the power or intensity of light at a fixed distance. (Intensity of light is divided by 4 as it goes out)

This was an exercise for proper lighting when shooting interviews. Jordan Schofield was our mock interviewer. In this photo we were using three point lighting, which included a main light or key light, a fill light or soft light, and finally a backlight.

In this photo, I have the camera plugged into my computer and I’m using video scopes in final cut pro to display what the luminance level is, to see if is correct. We wanted to have it at 50% light intensity, and at first it wasn’t so we adjusted accordingly to have perfect dispersal of light.

Here Pete Bendoris is standing on a ladder and adjusting the flood lighting for our green screen exercise.

After we had set up our lighting and got our green screen up Tony demonstrates using the light meter and points the sensor towards the light rays to find ambient light.

Here we tried a few contrasting aperture settings, then we tested different shutter speeds such as 1/50, 1/200, 1/500 ect.. we dropped and threw stones in a pile of flour using these different shutter speeds to see the differences between them.

Here we’ve set up the dolly track and are correctly attaching the tripod to the dolly to film our scene.

This is the dolly track all set up properly with the camera ready for filming. The set in the back ground is supposed to be a detectives office.

In this picture Jordan Schofield is using tree branches with our lighting to cast shadows on the background of our set. This will make the shot more realistic and believable.

Here we are beginning to set up our 3 point lighting, making sure all lighting wires are taped to the ground, the tripod is secure,  and our establishing shot for the drink awareness video.
