Careful calculation, timing and camera
location are needed for the required combination of dark sky and
a bright moon in just the right position to create a rainbow in the
spray from the falls.
Plus, plenty of spray. "2006 brought an unusual amount of snowfall
to the Sierra Nevada mountains - about twice the average. The spring runoff
was very high, causing both the thick mist critical to creating the bow
and the flooded meadow necessary for the reflection."
The reflection is a 'reflected bow' produced
by moonlight first refracted and reflected through spray droplets before being
reflected again by the flooded meadow.
