Half an hour after sunset the clear sky of the evening turned on an amazing glow and Pobbles Bay was bathed in this beautiful warm light.
This is what I often whitness at the end of civil twilight right before it gets dark. When you have a clear sky, don't despair, just wait till the end of twilight and quite often you'll get such an awesome glow as here.
I used a lee 0.6 hard GND + I think a lee 0.6 GND here to keep the sky dark enough but I also blended in a second exposure. If you are interested in how I do this check out my tutorial on the Landscape Photography Magazine
