Understanding Depth of Field: How Focal Distance Affects DOF, Visualized

Note: This is part two of a series on depth of field. you can read part one here.


This video is seen from a third person point-of-view, perpendicular to that of what the camera user would see. Depth of field is a phenomenon of near and far, forward and backward from the point of focus. Changing our point of view rotates the axis of the depth of the field 90˚ so that we may view it laterally across the X axis. This helps us better understand the optic principles at play. The overlays in this video visually quantify the changing depth of field at the given lens setting.
