Cairngorms tourists will be in the dark following a decision of the National Park Authority.

Planners have approved a plan for a camera obscura above the Coire Cas car park, enabling visitors to get a new view of the area.

The chamber will be in the existing garden area in a 19m tunnel. The structure will be made of weathered oak with a slatted timber roof.

Cairngorm Mountain Trust was granted permission at the authority meeting at Ballater last week. Work on the project must start within five years.

A camera obscura is a darkened chamber with a system of lenses which form an image on a surface. Users can then draw the scene being projected. Early pioneers of photography used camerae obscurae to produce their images. The term camera obscura literally means dark room.
