A circular polarizer helps to deepen colors throughout the (white light) spectrum. How it works is to cut out all the light except the light rays

that are flowing directly in the same direction as the filter allows. Due to this cut out of light rays, it is neccessary to open the exposure 5/3 stops.

So, on a sunny 16 setting @ 100 ISO, I set my camera to 1/100 and F 16, then drop the aperture to F-9.0 @ 100 ISO.I checked the color

temperature as well and the polarizer has no effect on color temperature.
