Photography: Art and Techniques Specialization

Overview

“As the distance away from any non-focused light source doubles, the light intensity decreases by a factor of four. Inverse Square Law is an important concept to understand. It has a lot of practical applications. In this lesson, I will give you an overview. ”

In this video lesson Domestika addresses the topic: Exponential Fall Off from Omni Directional Transmitted Light, which is part of the Domestika online course: Photography: Art and Techniques Specialization. Master basic camera skills, explore photography theory, and capture unique images using any type of camera.

“Exponential Fall Off from Omni Directional Transmitted Light. Previously, we went over some of the fundamentals in action. In this lesson, I want to go over another important aspect of light which is how it changes intensity the further you get away from a source. There's a rule called the inverse square law that states, "The further away you get from the light source, the intensity falls off exponentially.” To start with, we have a bare head which is as simple as it gets. It's just spraying light in all directions. It's coming away from this in a sphere coming out everywhere except behind ...”
