       3 Key Categories
The  easiest way to understand the world of filters is
to group them by function. Almost every filter falls
under one of the following 3 categories:
Chromatic, Non-Chromatic, and 
Special Effect
      Simply Put     
  Chromatic (color) filters  are used to change, alter,
or balance the color content of light.    
      Chromatic filters include several sub
    groups all of which affect color in some 
    way or another: color compensating,
    color conversion, color enhancing,
    color balancing, and  black-&-white
    contrast effects.

 Non-Chromatic filters  are used to change or modify
 the behavior or intensity of light.
This group includes: polarizers, NDs,
UV-absorbing, and optical flats.

 Special-Effect filters  are used to change or
the physical aspects of the image.
   This category is quite diverse and includes
   many intriguing groups: diffusions, mists,
    frosts, low cons, fogs, star effects, center clears,
    diopters, and multi-image attachments.
