>>3697549>polariztion of light works not on "visible light rays" level but on photons level. so when you shooting light also reflecting from an air's atoms and obstructing the light from an objects come to sensor>it's mean even fog is an object cause basically it's a drops of water>so with polarizing filter colors are more "juicy". everybody knows it but nobody understand why. and if you push colors on post process you'd get this inconceivable colors straight from the shot, almost without editingi forgot to mention that CPL removing photons reflected from an air cause they are more polarized than photons reflected from an objects cause while light reflecting from an objects he usually do few iterations and polarization of light reducing so light become not polarized. while there is no iterations in way of light reflected from an air so light is very polarized. CPL removing polarized light and keep only depolarized.
so amount of light reflected from air is reduced so you get more light reflected from an objects, so you get better color, cause color is combination of values of amount light that sensor's cell received through RGGB filters. so the color comes from LIGHT and therefore the MORE light you have the more COLORS you do have
same for a film. atoms of chemicals get more light and react better
digital sensor's cell is just literally a cell filled with chemicals that reacting to light with electric impulses. copper wire dlivers impulse to CPU and CPU combine signals from all cells to image.
cell is called subpixel. 1 subpixel have RED color filter 2 have green and 1 blue
it's called RGGB scheme sensor
so as you see the only thing that deliver COLORS to digital image (as well as to film) IS LIGHT. so then MORE LIGHT YOU DO HAVE THE MORE COLORS YOU HAVE
but in most cases light comes reflected from an air which you ain't need at all but you need an objects in frame. CPL is removing light reflected from air and delivers only light reflected from objects
