Heliopan 55 mm Linear Polarizing Glass filter - Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

Note!

Fully calibrated to indicate the axis of polarization and the convenient markings make the filters very easy to use on non reflex and non ground glass focusing cameras
With the calibrations all that is necessary is to hold the filter up to the eye and rotate it until the desired effect is seen; Note the position of any number on the rim, mount the filter on the lens and rotate the mount until the selected number is in the same position as when the filter was held to the eye
The effect can be seen through the viewfinder and changed by rotating the filter
The filter factor varies according to how the filter is rotated and its orientation to the sun
