I got up at 3:30 am to get a shot of a Lighthouse. I must be crazy... But the Community Foundation needed a photo of a lighthouse for their Annual Report, so off I went in the dark of night.
You must be there in the dark, find the best camera angle and be ready. Only a 10 minute window to shoot while the sky is dark but filled with color, and the pre dawn light warms the subject giving it shape. If the sun's rays peek above the horizon you loose. Go home and get up early again tomorrow.
