Lesson 1 - Inverse Square Law

Here is my example of using the Inverse Square Law to demonstrate that as the object gets farther from the light source, the intensity of the light reflected off of the object lessens. l=1/d^2

Additionally, we did an exercise where instead of using three grey cards placed one foot away from one another, we placed a black card in front, grey card in the middle, and white card in back. The challenge was to get the shade of all three cards to match by manipulating the distance of the light source. We were able to successfully complete this part of the assignment by moving the light closest to the front black card and focusing the radiated light upon this black card. Because the light was close and focused, less light reached the back white card and thus their colors looked similar when captured in the camera.

Amazingly enough, the photo above is of three different colored cards. From left to right: black, grey, and white.

This assignment will be helpful because it taught that placing an object close to a light source is not the best way to capture detail. Additionally, when photographing a crowd, placing a light farther away will ensure more even lighting upon the subjects.
