It was so dark that only 30sec, f2.8 and ISO 3200 would do for this brief take.
We zipped over to Tusan Cliffs last night, it was nice and completely dark. Unfortunate for us by the time we set up tripod, laid-down the mat ... dark storm clouds started moving in. After about 6 or so exposures, the dark clouds completely covered the skies. It poured even before we reached home 2330hrs!
