Modus operandi

GND filter is the abbreviation for “graduated neutral density filter”, also termed grey graduated filter.

A grey graduated filter is used to balance the difference in brightness of the horizon.

The reverse grey graduated filter does not have any uniform grey distribution, but rather a grey

gradation that in the middle of the filter runs upwards from dark-grey to light-grey and runs
downwards, ending in transparency.
This type of filter is much used to take shots of the sunset and sunrise. The filter is particularly effective when
the sun is at the point where it meets the horizon and the light is strongest in the centre of the subject.
