Generally about SOFT GRADUAL ND filters/usage:
SOFT GRADUAL ND filters have various density throughout filter space (from dark to light with soft transition). It means that light
incoming to camera is reducing gradually. This is very useful in situations where some of parts of the photography are overexposed
(too much bright sky - especially on straight horizonts).
SOFT GRADUAL ND filters are able to use with full or gradual filters in stacking mode.

Density in stacking mode example: ND4 filter + ND4 filter is equal to ND16 filter (density is multiplied).
