Walking along the beach in Exmouth last week, the clouds took on a pattern similar to the sand bumps on the shore.  My new Formatt-Hitech filter gave a warm purple tone instead of the customary cold blue of the Lee filters, lifting the colour of the scene. I was so pre-occupied with the scene that I did not notice the progressive surf.  Moments later, a wave washed in from my left and soaked me to the knee.  Worth it though.
