The light and colors in the sky at sunrise/sunset here in Barrow is nothing short of spectacular. The iPhone camera fails to capture the huge dynamic range. Even the HDR image I tried didn't capture the colors from the sun just below the horizon. At 1:00, it's still around 3° below the horizon. The first sunrise will be on January 23rd. I set up the GoPro on a window sill in the Barrow Arctic Science Center on time-lapse but the battery just doesn't last long enough. The start time is 10:30am and the battery ran dead at 1:05pm just before "solar noon". Maybe I can dig up a USB charger to run the camera on and try again tomorrow.
