Sunrises and Sunsets provide the same challenges in terms of dynamic range. Clouds add a lot and most of the time the best opportunities occur when the sun is below the horizon.
Here is my std set up:
Wide angle lens (14-24 mm) @ f/22
Tripod with level (unless camera has artificial horizon)
Generally shoot in Raw with 5 to 7 bracketed exposures at 0.7 or 1.0 stops.
If you cannot shoot bracketed then a graduated ND filter is a big plus.
The photo below is a single exposure and was taken last week with a D700 @ ISO 800, 1 second exposure @f/22.
Lens correction in LR3 and post processing using Nik color efx tonal contrast masked to exclude the sky.
May be dark on your monitor.
Hope to have time this weekend to merge the bracketed exposures into a HDR image so I can bring out the shadows.
