Daryl Benson's Reverse Neutral Density Graduated 3-stops filter
Sylvan Lake, Custer State Park, South Dakota, USA
beautiful man-made lake. Very hard to photograph rocks againts
the bright sky of a sunrise glow. The pictures shot with a
3-stops ND grad filter helped the rocks to be seen, keeping
the water under good exposure, but the sky behind was colorless.
The Singh-Ray Reverse Neutral Density grad 3-stops proved
itself the right one for this scene. We were so happy we began
to throw pebbles into the water.
