  2. VIEWSHED SIMULATIONS Step 1: Photograph locations Full-frame panoramic 24mm x 65mm 45mm Lens, 71º angle of view Standard 35mm Frame: 24mm x 36mm 45mm lens 43.7º angle of view (horizontal)

  3. VIEWSHED SIMULATIONS Step 2: Photos developed and scanned. Original transparency scanned at 4800 dpi. Brightness and contrast adjusted in Adobe Photoshop Step 3: Construct 3D model of turbine using dimensions from ACOE Section 10/404 permit application Step 4: Place turbine models at each of the locations given in the permit application Step 5: Locate camera positions based on GPS coordinates

  4. VIEWSHED SIMULATIONS Step 6:Locate in the model the horizon for each photo based on height of the camera as well as curvature of the earth and refraction Step 7:Locate in the model key landmarks visible in each photo. Step 8:Render each camera view using the horizon and key landmarks as control points Step 9:Create photo-montage by combining ‘before’ and ‘after’ photos using various tools in Photoshop to splice the modeled view into the photo
