This most delicate reddish-yellow conversion filter absorbs violet and some blue plus a minimal amount of green, but it passes yellow and red undiminished; the color of the light becomes â??warmerâ?? by 15 Mired. That is mostly the optimal amount for correcting the light blue cast in the shadows under a blue sky. It also absorbs UV radiation and hence it provides better sharpness.

Soft Image 49mm

Not to be confused with UV-blocking filters that photographers normally refer to as "UV" Filters. This one passes UV A radiation (320 to 385nm), but blocks visible light and looks pitch black to our eyes. It is used with appropriately sensitized films in such applications as ultraviolet reflection photography in forensics or in materials research, but also as filters on UV-emitters for flourescence photography. Depending on the illumination, its

Cross Screen 4 49mm

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. Its filter factor is approximately 2.

023 Dark Yellow 49mm

This filter has an effect similar to that of the medium yellow filter, but it also darkens red colors. Clouds in the sky gain more contrast, a red roof and red flowers are rendered darker in relation to plant greens (as they would not with a purely yellow filter). The yellow-green filter accentuates the delicate springtime green in nature, it makes portraits more dramatic. Its filter factor is approximately 2.
