ND filter
A Neutral Density
filter or ND filter is a "grey" filter, it appears gray and reduces the
amount of light reaching the film or sensor, but does not have an effect
on color balance.
The purpose of standard photographic neutral density filter is to allow
the photographer greater flexibility to change the aperture or exposure
time, allowing for more control, particularly in extreme circumstances
such as on a very bright day.
This filter can be used to prevent strong overexposure even when using a
slow shutter speed. It's perfect for shooting in heavily-lit settings or
for extended exposures. For example, when you use a slow shutter speed to
capture a bright moving object, such as a waterfall, this filter is your
best choice. See the pictures below for comparative shots of a waterfall
taken both with and without the use of this filter. The ND Filter we offer
is double thread with 2×, 4× and 8×(ND2 ND4 ND8) to indicate the amount of
light a ND filter can reduce. Different neutral densities have different
effects. You can use the filter individually or in any combination to meet
your demand.
ND2 filter can reduce light transmission by one
stop.
ND4 filter can reduce light transmission by two
stops.
ND8 filter can reduce light transmission by
three stops.
UV filter
UV filters are used in sunscreens
to protect in photography to reduce haziness and fogginess created by UV
light.
CPL filter
It also could remove reflections
in water; therefore, you can see the detail in the water or river bottom
during shooting a river scene. It is also good with foliage, making leaves
and less shiny.
Soft filter
This filter reduce contrast and create a soft halo
around the highlights, they are also ideal for creating a hint of softness
or blurred contours. They are very suitable for portrait especially for
close-up shoot, which can soften wrinkle, spots, pore etc, giving a
gentle, flattering effect. You can obviously find the differences from the
above pictures that with or without this filter.
