Alyn suggested we get right below the lighthouse and shoot up for a clean and dramatic composition. We carefully positioned ourselves so we got the most of the lighthouse beam, which covered a 180-degree arc. Alyn suggested I use the Tungsten preset for accurate white balance, and the LCD spirit level for a level shot. Shooting at 14mm meant that the stars surrounded the top of the lighthouse. The clear sky and residual light from the beam meant I could shoot at ISO3200 and capture a good exposure.
