English: Effect of aperture on blur and DOF. The points in focus (2) project points onto the image plane (5), but points at different distances (1 and 3) project blurred images, or circles of confusion. Decreasing the aperture size (4) reduces the size of the blur circles for points not in the focused plane, so that the blurring is imperceptible, and all points are within the DOF.

Still wasn't right. Out-of-focus points result in a smaller circle with the same intensity, in-focus points stay sharp but get dimmer, background gets dimmer.
