Hi everyone. So I generally shoot black and white with a yellow filter (y2) and I understand the effects it has in relation to the colors of a scene. What I am trying to figure out is what type of filter would help add contrast on overcast days with a snowy landscape, often times I find these scenes lack colors, or are mostly blue. Could a polarizer help or hurt? Is the yellow filter still a good choice under these conditions? Any help is appreciated, thanks guys.
