Depth of field depends on the subject distance and aperture you choose and is indicated by the lines on the depth-of-field scale corresponding to the aperture. ˎˎ The To use the plug-in polarizing (circular) filter To set the subject distance depth-of-field scale and depth-of-field table are for 35mm-format cameras. [. . . ] You can adjust the polarizing degree to get good contrast when taking photos of blue sky. ˎˎ Generally, reflected light (polarization) should be minimized in photography, however you can adjust the polarizing degree for the desired effect.
