Assignment 2 the 3 Laws of Light

Assignment Description 

In one photograph using one light source clearly demonstrate the 3 laws of light at work. Include the light source in the photograph. The subject is the light. Think of it as more of a physics project than a photograph. Use a dodging tool  to prevent the light from flaring the lens.  Try to crop out any rigging you might use and make the image about the light.

-inverse square law

-the angle of incidence equals the angle of reflection

-light travels in a straight line

Assignment 1 Inverse Square Law

Assignment Description 

1. Using 3 identical 4x5 grey cards set 1 foot apart, overlapping slightly and placed at a 45 degree angle from the camera angle. Make 4 photographs of the cards with the light 2 feet, 4 feet, 8 feet, 16 feet and 32 feet from the middle card. Use an incident meter on the middle card to give the correct exposure. The middle card should have the same value on each photograph.  Use Lightroom to weak the middle card until they all read the same value.

2. Use 3 4x5 cards a black card in front, a grey card in the middle and a white card in the back. Using the same single point source make all 3 cards appear to be the same value. You can move the cards and the light source until it works.
