5 vertical shots with a 24mm tilt shift lens stitched together in PS6. I climbed up onto this log and walked to the end hanging over a cliff. I carefully balanced my tripod and set up my lens to capture the background and foreground in sharp focus. The sun had already dropped below the horizon and the sky turned a purple-blue. There was still enough warm light on the horizon from the sunset to light the scene. I love this time (called civil twilight) because the shadows lighten up and the light softens - natural HDR if you like. I used a Lee 2 stop ND filter to hold the sky and the exposure was set at 13 seconds at F16.
