To many, the circle of confusion is well named as it can be a tough subject to understand. In this video not only will I help you understand it, but I’ll show you why it matters.
What is it?
The circle of confusion defines the transition point in-between what appears acceptably in focus and what is out of focus. It works like this: take a point of light from in front of the lens. That light travels through your lens and it is focused down to the focal point. The focal point is where the light beams cross, or converge behind then lens. When the focal point falls on the focal plane, which is where the cameras sensor is located, that subject is in sharp focus, or what we call “critical focus.”
