For B&W photography. Increases contrast between Orange and Blues. Oranges are lightened while Blues are darkened. Especially suitable for portraits. These Leica M-Filters are made of optically pure glass, parallel plane ground and precisely annealed. Thus the full performance of the Leica M-Lenses is retained even with a filter attached.
By modifying the conversion of colours to greyscale values, these lens filters offer new opportunities for the exploration of creative effects with light and contrast. This means that the colour of the filter in the original scene becomes brighter and its complementary colour darker. This is effective for creating unusual moods in landscapes, portraits and other genres of photography. At the same time, multilayer coating reduces reflections and ensures high transmission without vignetting.
