Location : Pontsticill Reservoir or Taf Fechan Reservoir in South Wales. It lies within the Brecon Beacons National Park and holds approximately 3400 million gallons of water.

This image was captured shortly before dawn using a tripod-mounted Canon 5DmkIII camera and a Canon TS-E 17mm f/4 L lens. I used Live View focusing at 10x to focus on the gantry. The camera was set to manual exposure mode, f/7.1, ISO 800 and daylight white balance. The exposure was 30 seconds; it was really quite dark at 6:30am (more than an hour before sunrise)! The RAW processing and the final adjustments were all done in Photoshop CS/6.
