Digital High Grade Filters
The DHG Circular Polarizer allows you to eliminate unwanted reflection from water, glass, etc. It also helps saturate colors and increases contrast. The DHG CPL is often used to enhance blue skies and white clouds. The thin frame allows it to be used with wide angle lenses. Front threads accept a lens cap.
Light Control 8 (ND8)
With the ND8, you can open up the lens or slow the shutter speed 3 stops from where you would be without the filter.
This enabes the photographer to:
A - Use slower shutter speeds at higher ISO's to show movement in waterfalls, cars, etc.
B - Use wide apertures to narrow depth of field for effect.
C - To use video cameras with fixed shutter speeds in very bright situations like snow that would cause over exposure.
The ND8 doe not affect color rendition.
