I’ll say it straight away : this shot was not planned at all.
During a trip in the Pyrénées (southwest France) my girlfriend and I decided to climb to the Lac de Gaube just before sunset. We didn’t know exactly what kind of view we would get at this lake. The ascension took us more time than expected and we arrive on location after sunset.
Once up there, I found the view beautiful, so I decided to quickly set up my camera for a blue hour shot. It turns out this location is really beautiful, because after that I was able to shoot the Milky Way appearing just between the mountains.
