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.
Jun 20, 2021 · 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’s size is what affects the sharpness of an image. The smaller the circle, the sharper the image. And the larger the circle, the blurrier. It is often written as CoC.
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.

Jun 7, 2021 · Photographers refer to the measurement of such optical blurs as the circle of confusion. When you enlarge a photograph beyond a certain size, you may notice that parts of the photo that once appeared sharp now seem blurry. In fact, the larger the print size, the more blur the human eye can perceive.

May 13, 2022 · That, in essence, is the concept of the circle of confusion. The circle of confusion is a photography phenomenon. With our natural vision, we experience no circle of confusion. This circle of confusion happens because light passed through a series of lens elements from different distances.
