In optics, a circle of confusion (CoC) is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. It is also known as disk of confusion, circle of indistinctness, blur circle, or blur spot . In photography, the circle of confusion is used to determine the depth of field, the part of ...
Jun 20, 2021 · The circle of confusion is the measurement of where a point of light grows to a circle you can see in the final image. Also called the zone of confusion, it’s measured in fractions of a millimeter. The circle of confusion is what defines what’s in or out of focus. This number is also what calculates depth of field.
The Circle of Confusion occurs when a point of light from an image enters the camera through the lens and lands on the sensor at the back of the camera. It’s a measurement of a point of light that falls on the focal plane (i.e. camera sensor) that’s often referred to as the focal point. When we move the focus ring to focus the image, the ...

Jul 5, 2022 · According to Wikipedia, when we're thinking about optics, "a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source." When a lens focuses, every point of the subject gets projected as a point onto the camera's sensor. A single point on a subject is only ...
May 13, 2022 · The Degree of Tolerance with the Circle of Confusion in Photography. The circle of confusion is basically about the degree of tolerance that the human eye has. Your eyes make a clear distinction between a subject that is out of focus and one that is in focus. Before this happens, there is what is called the circle of confusion.
