HOYA offers a wide variety of superior quality filters for use in all imaging
applications such as 35mm SLR cameras, Medium Format, Large
Format, Video, Movie and Digital. It is important to select the best filters
for your needs, as choosing inferior brands can deteriorate the 
performance of your high quality lenses. HOYA filters guarantee you the
highest standards so you can create the best images.
In order for you to fully understand the wide range which HOYA offers,
the four main categories, into which our filters are grouped, are explained
below:
GENERAL FILTERS
This group includes everyday filters which can be left on your lenses,
such as Skylight 1B, UV and Polarising. These are the first filters that
every photographer should ensure they own. Skylight and UV filters
should be constantly fitted to a lens to give improved clarity and color
balance as well as offering protection to your lens. Polarising filters
have several uses such as eliminating unwanted reflections, 
increasing color saturation and enhancing contrast. As to whether you
should use Circular Polarising or Linear Polarising filters with your
camera, we recommend that you refer to the detailed explanation later
in this catalogue.
CREATIVE FILTERS
This is a new classification, exclusive to HOYA. Although similar to 
general filters, they produce a subtle, but realistic result which may be
used to artistic effect. They are also suitable for use as everyday 
protection filters and may be combined with other types such as 
Circular- PL and UV for enhanced effect. In this case, we recommend the
use of HD Filters or PRO1Digital series models which have thin rings and 
multicoating to avoid vignetting and ghosting.
COLORED FILTERS
As their names suggests, these filters use HOYA colored glass. They are
used for color correction of different light sources when using color film,
or for controlling contrast with Black & White film. Color correction filters
are important as color films do not have the flexibility of the human eye
to automatically adjust to different situations. Black & White films register
colors as shades of grey and the rendition of each color in a scene is
important, so filters can be used to control this. The color of the glass
used in all these filters is carefully controlled and to reduce the possibility
of color shift over a period of time, such high quality filters are coated or
multicoated on both sides. This maintains the desired effect and gives a
long service life.
SPECIAL EFFECT FILTERS
As you saw in the previous pages of this catalogue, HOYA makes it 
possible to add many different special effects to your pictures, such as
star-bursts, close-ups, softening and multi-images. It is simple to achieve
outstanding creative or unusual results and take special photographs for
memorable occasions such as weddings, birthdays and holidays.
