Polarizers
A
circular polarizer has the same effect as a normal
polarizer and is used on cameras with beam-
splitting metering systems commonly found on
autofocus and digital SLRs.
Polarizer filters give you several key creative
features. They evenly increase color saturation of
all colors (except black and white), creating deep,
rich scenics. They add contrast for dramatic skies
and arial shots. They eliminate the whitish glare
from highly reflected surfaces like glass and water.
Polarizers are two part lenses that rotate, allowing
you to select the degree of additional saturation,
contrast and glare reduction desired. Polarizers are
offered in standard and warm versions. Warm
polarizers add warming filter, giving portraits and
scenic a warm and muted feel while retaining rich
coloration. Polarizes come in two types: Circular --
for all types of cameras: required for beam
splitting metering systems commonly found in
auto-focus SLR's and in most current TTL SLRs.
Linear -- for older metering systems.
