Photo trickery makes wind farms smaller

Wind Farm developers have been accused of deceiving local councils and the public by using computer-generated images in planning applications that make the turbines seem smaller than they are in reality. The claim is contained in a new book, Windfarm Visualisation: Perspective or Perception, by the architect Alan Macdonald, whose company, Architech, specialises in computer- generated images.

Wind Farm developers have been accused of deceiving local councils and the public by using computer-generated images in planning applications that make the turbines seem smaller than they are in reality.

The claim is contained in a new book, Windfarm Visualisation: Perspective or Perception, by the architect Alan Macdonald, whose company, Architech, specialises in computer- generated images.

A separate study by the University of Stirling found serious flaws in the images that are presented as part of a visual impact assessment in the planning process.

Macdonald said the accepted practice was for a photograph of the landscape where the turbines are to be sited to be taken on a camera with a 50mm lens. This is then "stitched together" with other 50mm shots to create a long, shallow panorama on an A3 page.

But the human eye does not take in the whole panorama; it focuses on the middle section where the computer-generated images of turbines have been placed, giving the impression of a small development on a large landscape.

"A printed 50mm photographic image will always under-represent our perception of the scale of a more distant object because we are looking at a flat image devoid of any depth information," Macdonald said.

The only way someone can get a realistic impression of what the turbines would really look like is to place the image on a curved display, with one eye closed.

The University of Stirling report also found the use of the industry-standard 50mm lens to be misleading.

However, RenewableUK, the wind energy industry body, said: "It is in developers' interests to ensure that their visualisations are accurate."
