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 · What is the circle of confusion? 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 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.

Jul 5, 2022 · A single point on a subject is only registered as a point on the camera’s sensor if the lens is precisely focused at the right distance. Otherwise it will actually be recorded as a circle (known as a ‘circle of confusion’). Use this diagram to help you when it comes to the circles of confusion.
Dec 9, 2021 · The circle of confusion (CoC) occurs at the point where an incoming ray of light intersects with the plane of photography. The shape of the lens bends the incoming light. The diameter at which the focal plane intersects this optical column determines how "in focus" this part of the image will be.
