Lighthouse - Portland Bill at night (9min f/5)
Took a late-nighter with Dan and Adam. Travelled 100 miles (each way) to shoot the lighthouse but the sky was unforgiving, the temperature was low and the wind was bitter.
Had no choice with composition - wind was easterly so facing pretty-much west to avoid spray, and the tripod was on the deck to minimise vibration from the wind. Of the lighthouse shots, this was the best of the bunch - 9 mins at f/5! It's no wonder you don't see many photos of lighthouses at night...
Moved on from here to a local industrial estate with loads more potential :)
