Assignment 2: Inverse Square Law

Card distances from light: 2'/4'6"/12'

Setup

My understanding of the Inverse Square Law is that the intensity of light cast upon a subject falls as the distance between the source of light and the subject increases. With this in mind, our group set up the three cards from darkest to lightest. The black card would have the highest light intensity, so it would appear lighter in the photo. The white card in the back would have the least light cast upon it, so it would appear darker in the photo.
