Spectacular "double" rainbow over Pauatahanui Inlet as seen from Motukaraka
Point. This image was taken with the 24.6 megapixel Sony Alpha A900 camera
using the Carl Zeiss F2.8 24-70mm lens.
It is interesting that, in this photograph, you can see a secondary rainbow
outside the primary bow. This phenomenon is described in "Wikipedia, The
Free Encyclopedia" as follows:
"Occasionally, a second, dimmer, and thicker secondary rainbow is
seen outside the primary bow. Secondary rainbows are caused by a double
reflection of sunlight inside the raindrops, and appear at an angle of
50°–53°. As a result of the second reflection, the colours of a secondary
rainbow are inverted compared to the primary bow, with blue on the outside
and red on the inside. The dark area of unlit sky lying between the primary
and secondary bows is called
Alexander's band, after
Alexander of Aphrodisias who first described it."
Shown below, the double rainbow photograph has been
cropped so that it can be printed as a wide panorama. This is a nice
alternative to the double bow presentation, but it can show only the primary

obtain the best appreciation of the quality of the images on this site, they
should be displayed at a relatively small size, because each image has been
reduced in size to a maximum width of only 870 pixels, from the original
width of at least 4900 pixels (or 6000 pixels from my full frame cameras).
In addition, the images have been saved at a low quality setting.
