Depth of Field P.2

Answer the following questions in an in depth - paragraph:

1. What is the circle of confusion?
2. How does this affect what the viewer of the image perceives overall?
3. How does the camera's sensor come into play with the circle of confusion? Why?

The circle of confusion is defined by the size of the spot of light that is acceptable to be considered "sharp enough." This is a subjective matter that its accuracy is generally determined by the size of the print or screen that the content is going to be viewed in. In general terms, the bigger the projected screen, the smaller the "acceptable spot of light" becomes. The circle of confusion is altered when speaking in terms of digital mediums. Because digital mediums are captured in pixels, the circle of confusion is defined by the size of the pixel. The smaller the pixel sizes, the more accurate the focus has to be in order to be considered in focus. Thus, as a result, the higher the resolution, the shallower the depth of field. In other words. A smaller sensor will inevitably create a shallower depth of field.
