Warm filter
Encyclopedia
A warm filter is a photographic filter
that improves the color
of all skin tones and absorbs blue cast often caused by electronic flash or outdoor shade. Adds warmth to pale, washed-out flesh tones and are ideal for portrait
s as they smooth facial details while adding warmth to skin tones (for color imaging)
In general, they suppress blue casts on overcast days and on subjects lit by blue sky.
Photographic filter
In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. The filter can be a square or oblong shape mounted in a holder accessory, or, more commonly, a glass or plastic disk with a metal or plastic ring frame, which...
