Dutchman Falls, Worlds End State Park

I timed my Dutchman Falls (near Worlds End State Park) photography so that the sun would be completely set at this vantage point - to avoid any hotspots in the frame. Plenty of small streams of water make a wide variety of compositions available at this location.
 
I generally use manual exposures when photographing waterfalls. Set the aperture for the depth of field/sharpness needed, set the ISO to 100 (usually) and set the shutter so that a very small area of the brightest water is overexposed (blinking highlights).
