Leica Filter Orange, E49
The effect of this filter is quite powerful. It darkens violet and blue very strongly, green strongly, it even darkens yellow-green a bit. Landscape- and architectural photographs have an increased, virtually “graphic” contrast, clouds in the sky already look dramatic. 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
Leica Filter Yellow, E49
With strong blue suppression, which extends into the blue-green, clouds in the sky look very natural, but not yet dramatic. Distant views with light haze become clearer. An ideal filter, especially for landscape and plant photographs.
