The effect the B&W 95mm 040 Yellow-Orange (16) Multi-Coated (MC) filter is quite powerful. It darkens violet and blue very strongly. It even darkens yellow-green a bit. Landscape and architectural photographs have an increased, virtually "graphic" contrast.
More dramatic effects are possible with orange filters with clouds starting to jump off the print when photographed against a clear blue sky. It should be noted that if orange still does not produce the desired effect, a red filter will give maximum boost to your contrast. And, if a polarizer is used in conjunction with these filters, the effect of a threatening storm can be achieved.
Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Because skin tones are strongly lightened in relation to the green tones of plants, this is a favored filter for nude photography outdoors - because it raises the contrast between the lighter bodies and darker landscapes
