I normally use red, orange, green, and occationally polarizer filters with my B&W landscape work. On a dark, overcast day, is the use of filters greatly diminished, or just subdued? Is it worth it at all? (aside, for example, of a polarizer taking the sheen off surfaces, etc.) I know, I should run tests, but time is tight, and I appreciate the expertise of this forum ! thanks mark smith(posted 8159 days ago)
