Description
Similar to UV filter. Eliminates ultraviolet rays. Re-
duces haze and bluish tones in daylight photography.
Effective with color film only. May be used at all times
to protect the lens.
Eliminates undesirable ultraviolet rays which cause dull,
flat pictures. Renders subject in clear detailed brilliance.
May be used at all times to protect the lens.
Reduces the quantity of light entering the lens to 1/2
or 1/4 of the original intensity. For use in extremely
bright conditions when you wish to maintain a wide
aperture.
Enables you to take pictures through glass or water
without reflections. Will darken the sky in black-and-
white photographs without altering other color values
in the picture, and renders blue skies darker when used
with color film. Reflections are reduced to provide
better texture surface detail.
Accentuates contrast, darkens blue skies. Very effective
in daylight scenes where the sky is part of subject mat-
ter. Heightens the effect of white clouds. Usefull in
copying documents where line copy is blue or black
on light background.
Absorbs a wider range of wavelengths from UV to dark
green than the Y2. Makes a superb rendition of the tex-
ture of outdoor subjects, and indoors. It brings but
detail in objects yellow, brown. Used with infrared
film.
Used as contrast filter to create darkened sky or in copy-
ing. Also used to penetrate haze in landscape photo-
graphy for stronger contrast than an O2 filter. Used
with infrared film.
For use when taking color pictures in cloudy or rainy
weather. Reduces bluish tone.
Designed for use when taking color pictures in early
morning or late evening hours when red rays are pre-
dominant.
