I took this image in August 2012 returning from a trip up the West coast.
It was taken in the early evening from the ferry which goes from Craignure (Mull) — Oban.
It was cloudy but, just as we reached the Isle of Lismore, the sun broke through the clouds and lit up the lighthouse on the edge of the island.
The image was processed slightly afterwards to make the clouds more prominent and avoid a bland sky.
Taken with my Nikon D5000 at 400s, f10 at 200 ISO.
