Last moments of the day make me keep coming back to these spots. It is only the long and slow scramble back to town in the dark that keeps me from wondering too far into the distance.
'Focus bracketing' in the dark is quite an interesting technique. The Sigma 18-35mm lense really is usefull only when manually focusing through Live View or while shooting video. Stupid purchase but now making the most of it while pushing the limits of the setup with the Canon 70D.
