WebMore details about Depth of Field (DOF) Circle of Confusion (CoC) is generally used in two ways. Circle of Confusion (CoC) is the computed diameter of the blurred size of a hypothetical "point" (theoretically of original size zero if in perfect focus), calculated at the sensor, before any enlargement to viewing size.It is a math concept (and Not any actual … WebThe 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 …

How do depth of field and the circle of confusion relate to pixel size ...

WebWith digital sensors, the size of the pixel determines the size at which the circle of confusion (CoC) becomes significant when viewing at 100% crops. Any blur circle smaller than the pixel pitch will be recorded as a single pixel. Only when the blur circle becomes larger than an individual pixel will it be recorded by two adjacent pixels. WebThus, sensor size is used to calculate the enlargement of a blur spot given by its proportion with image print size. Maximum print dimension: The size you want to print ...
