Lesson 1 Inverse Square Law

The inverse square law states that the intensity of a light diminishes inversely square to the distance. i=1/d²



Assignment 1 The Inverse Square Law
1. Using 3 identical 4x5 grey cards set 1 foot apart, overlapping 1"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.


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.
