OPP (other people's photography)

This. I wish I knew how long this was exposed.

From the photographer on reddit: its a composite image of 7 photos taken with 15 second exposure on each. and like “kevyB” posted, the shoreline was post-processed in photoshop. EDIT: also “biga29” was correct in stating that there was a Type of tripod used to rotate opposite of the earth’s rotation, to cancel out the star trails.

“We all live under the same sky, but we don’t all have the same horizon” –Konrad Adenauer.

Horizons is a landscape photography exhibition composed of images with a strong central vanishing point in common. The intention of the project is to capture the infinity of ways, the beauty of variety and the fortune of being able to choose.

Carried out by Marta Cascales Alimbau (pianist and composer) and Carla Cascales Alimbau (graphic designer and illustrator). Born in Barcelona, we are two sisters who, attracted to any kind of artistic expression, have found in photography a way of transmitting our view of the world.

Exhibition July 16 to October 8, 2012. Hotel Eurostars BCN Design, Barcelona.
