Generally about REVERSED GRADUAL ND filters/usage:
REVERSED GRADUAL ND filters have various density throughout filter space (soft transition from light to dark then hard transition from
dark to light). 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 sunsets and sunrises).
REVERSED GRADUAL ND filters are able to use with full or gradual filters in stacking mode.
Density in stacking mode example: ND8 filter + ND4 filter is equal to ND32 filter (density is multiplied).
