Full Moon effect on HDR

It is interesting that tidal forces may affect the HDR. For example, there is a full moon effect on the HDR detailed by HDRKID.

Mainly, this effect causes the HDR work better on the morn of a full moon. Also, it performs better when there is a new moon which leads me to believe that the effect might be tidal. This could be a breakthrough, but more tests need to be done to prove that there is a tidal effect.
