My daughter Kerry was travelling in New Zealand and in April this year I visited there to catch up with her. We ventured to the South Island’s remote Fjiordland National Park and cruised up the mighty Milford Sound. This iconic location is hemmed in by huge mountains, imposing cliffs and thundering waterfalls. I anticipated taking some great pictures to be briefly frustrated by heavy overcast skies and persistent drizzle. I needn’t have panicked. The sun broke through and the clipper sailed into position just as the rainbow revealed itself. Within seconds, the moment was gone, but I had my picture.
