Hiked to this spot to catch the midnight sun peaking inside the fjord of Ólafsfjörður, north Iceland.

The plan was to catch the sun as it appeared from behind the mountains, and everything went according to plan. Even managed to get this nice star effect.

Shot this weekend during summer solstice, at Ólafsfjörður, north Iceland. This was pretty much as low as the sun went, being blocked by the mountains. Then it began to rise again. The mist that can be seen creeping in the fjord was actually all over in just a few minutes, and you could see about 5-6 meters in front of you in any direction. Luckily I managed to get a few frames before that…
