Elevated Aerial Mast Photography For Architectural 3D Rendering in Phoenix AZ

I got a request from Renderthis for a single wide angle photograph of an empty lot just south of the Phoenix airport to be used as the back ground for a rendering they were doing for a Architectural client.

When photographing for a rendering the location and time of day are very important to get right the first time. While doing the actual rending the location of the camera and position of the sun can be set to match the actual photograph ensuring that the shadows match the surrounding buildings.

We used a Luksa HiView-46 push-up mast at its full 46 foot height with a Photoshipone 3XPro Mast mounted 3 Axis RC controlled Camera Gimbal for adjustment of the Nikon D700 camera with 24mm lens mounted on the gimbal in Portrait Orientation. We used Nikon Camera Control Pro with live view on a Apple MacBook Pro to compose the photograph and adjust the exposure after viewing the histogram. After deterring the exposure we shot a 5 photo bracket at each position with two over and two under ensure we properly captured the hi lights and shadow details.

We use a iPhone Application Sun Seeker that maps out the position of the sun to determine the time of day and then Google Maps for an Aerial view of the property to determine the location of the Mast. The Aerial photo showed that there were power lines along the south edge of the property would not allow us to place the mast in the original location, we had to move the mast 75 feet north to allow a “Generous” buffer from the power lines.

We considered the various lens options to determine the field of view required for the client.

We coordinated with RenderThis and after confirming the new location we suggested shooting with a 24mm lens in the Portrait Orientation with 4 over lapping photos that would be stitched together with the PTGui application.

We actually took 6 overlapping photos to ensure that we properly covered the angle of coverage plus a bit more for insurance. When the stitching was done the first and last photo was dropped only using 4 which resulted in a Pano that was 130 Degrees wide. Only a portion of the file was used for a final angle of view of approximately 110 degree horizontal angle of view.

The final stitched image after some photoshop enhancement, a smaller portion of the photograph was actually used for the rendering.

And here is the final photograph that Renderthis produced for their client.
