It makes me think of an image I took at White Sands, NM last October that has rippling waves of brilliant white sand that I took on ANPAT 12 that I am still studying how best to present it. Mine however is only the sand since I started out with the idea of creating an abstract. I will probably look at some filter options in LR4 and/or Nik. Thanks for posting. As always you generate ideas for us.
