beside GND, CPL, Big Stopper .. another filter that always with me is Reverse GND … and I am using Singh-ray for quality capture (it produce very less color cast as Lee Filter do)
when this filter been use ? (many ask) … as dusk/dawn time the sun always stay near horizontal level which make near horizontal level over expose and make details lost ….
horizontal near sun area lost details due to the overexpose and not able to rescue by the GND filter …
so with the GND help … I can balance the horizontal level exposure and recover some details as shown
hope this simple share will clear … most of the question from my friends .. “when RGND need ? ”
few more sample of RGND capture
