In the video you just watched, you learned about how Jeremy uses math to get the right exposure for the special effects he creates. The challenge now is to use the light probe readings to find the mathematical relationship between light intensity and distance so the light source is the correct distance from the exploding flower.
The flash power, or intensity of a light source, is often measured with a light meter in a studio, but intensity readings can vary based on the distance from the light source. Understanding light intensity and how it changes, or varies, with distance can help the photographer to achieve the proper lighting for a given shot.
You will solve the challenge on the next screen, but before you do, think about the questions below and record your answers:
What are some situations in your daily life where you may need to apply the concept of variation between two sets of data, where one variable changes and another changes proportionally?
Why you would need to look for the variation between light intensity and distance in this challenge?
