Blue Moon

I know, the moon is not really blue. Further explanation will follow:

This is an experiment with the photomatix software.
This image is a composite of three exposures (normal, plus 2 stops and minus 2 stops). The software creates a high dynamic range (HDR) image of 32 bits.
Of course, it is impossible to display 32 bit images on a computer monitor, so the software will also produce a tone mapped image, which is what you see here.
The technique does allow more details to come out in areas that would otherwise be too dark or too light from a single exposure.
I had to retouch the moon, because it moved quite a bit over the time of the three exposures.

The "blue moon" is the rare (but arbitrary) occurance of a second full moon in the same calendar month. The phrase is over 400 years old, and the origin of the term is lost to antiquity. May 31, 2007 was a "blue moon" day. This is the full moon rising over a small lake near my home.

A happy blue moon to all my FC friends!
