I have become real good at capturing sunset shots it seems. Repeated experimentation and trial & error, and here is the result of some of that (I am sure gazillion people used done the same techniques before, but even Christopher Columbus must have been mighty thrilled discovering America when the Vikings had already done so).
1. 1/100s, f8.0, ISO 200, Cloudy White balance
This one is my favorite. Zoom right into the sun in aperture priority with a high aperture and meter for exposure. Cloudy white balance works best just before and after sunset (Sunshine is preferable before that). If the camera has AF lock, keep the focus locked, zoom out and click. Or what I did was switch to manual, increased f but used the camera recommended exposure time. Thats why the photo looks darker than it really was.
2. 0.3s, f6.3, ISO 200, Cloudy White balance
All exactly the same as the previous photo, but metered by zooming into the point where the sun had just set. Of course, reduced light means longer exposure time. (2) was taken 25 minutes after (1) from exactly the same point.
3. 0.4s, f6.3, ISO 200, Tungsten White balance
Taken more than half an hour after sunset. I figured the colour temperature of the late twilight light was similar to tungsten light (I later learned it is not actually) so tried taking this one with tungsten white balance but surprisingly the sea is in a very genuine shade of deep blue, which is what I wanted to capture in the first place.
4. 1/125s, f8.0, ISO 100, Daylight White balance
Nothing special, except that I used high DOF so that the waves, sun and sky were all in focus. I guess this photo should have been taken in ISO 200, lots of time to try that.
PS: All photos were taken in the same place, but at various times of day (and tide)
PPS: As always, no digital modification whatsoever.
