Effects of Filters
These filters, manufactured from the finest solid optical glass, are ground and polished to the most practical thinness. In addition they are heat-treated to avoid any distortion or focal shift, and each filter is subject to strict tests in order to ensure a perfect even surface which is essential to a good filter.
|UV||Transparent||Absorbs ultra-violet rays without increase of exposure, thereby preventing haziness and foggy effects in distant landscape. It creates clearness. Constant use of this filter is recommended for clearer pictures as well as a lens protector.|
|Skylight||Light Pink||Creates the effects given by Y2 filter in case of black and white film. Reduces excess blue and adds warmth to the pictures. All purpose filter.|
|Polarizing (PL)||Gray||Removes or reduces reflections from non-metallic surfaces, darkens blue sky while increasing color saturation penetrates haze. Simply rotates the filter in its mount until the optimum effect is obtained.|
|Cicular Polarizing (C-PL)||Gray||It is similar to the ordinary polarizing filter, except rays go circular, no linear, after passing through the circular polarizing filter. It eliminates possible exposure errors which may be caused by the slight polarizing of rays in cameras of the TTL system using fixed mirrors.|
