The "blue hour" above the Gemsstock
The term "blue hour" refers to the colour change of the sky during twilight
This happens immediately after sunset and before nightfall. During the blue hour, the deep blue sky has about the same brightness as the artificial light of building and street lighting. These intense colours in the early night sky are very popular with photographers.
These photos are taken by Lisa Planzer from Bürglen (UR). Her Instagram account contains countless landscape images from the region.
