Another member of my course (whose name completely escapes me) takes a shot of the Dangerous Current sign on the beach. What's of interest to me is that the light on that day seemed to be incredibly kind (not too harsh, but bright enough to give vibrancy to the colours) even to those of us who had little idea what we were doing.

Addendum: My personal opinion is that Facebook is a sociopathic organisation that steals other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so. Facebook going out of business would IMO be a net gain for humanity.
