On this occaision, it was a bright, cold, clear day, with lots of great skies, good light, wet sand and wide open spaces. Hardly a soul on the beach, except us.

This one appealed to me because the sand was wet, picking up the reflections of the sky, which looked huge through the wide angle lens.
Mono seems to work better than colour in this case, since it gives emphasis to the tones rather than it all looking blue.
