CPL filter
What does CPL filter do?
Firstly, it can darken blue skies turning them a deep, rich blue.
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.

It removes reflections from non-metallic surfaces:
Skies
Color Enhancement
Water and reflective surfaces
Light absorption

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.
