Part of the joy of landscape photography for me is standing around and waiting for the light to change. You put your camera on its tripod, compose a shot and wait, taking photos every few minutes, whenever the sky or light or whatever looks interesting.
I caught the tail end of a storm in Santorini, Greece, with heavy clouds blowing over right at sunset. An hour or so later and it was blue hour, with streetlights and buildings lit up. Both photos are below, after being edited in Lightroom using the Lightroom Develop System.
