Vertical Panoramic Images – Tilt/Shift Lens

February 23, 2011

Here are a few images from my visit to Kraftwerksdenkmal Vockerode, a shutdown power plant, near Berlin, Germany. These images are vertical stitched panoramas, taken at a similar locations in the power plant but at different platform levels.

These panoramas were created by stitching images created with a Canon Tilt-Shift lens. This technique creates a different looking image than panoramas created by rotating the camera/lens around the lens’ nodal point. For these photos, the camera is in portrait orientation. I tilted the lens to maximize front to back focus and then took three exposures at different shift positions. The first exposure was taken with no shift, the second with the lens shifted fully down and the third with the lens shifted fully up. The images were then combined in Photoshop CS5. I prefer to combine all three frames. As the two frames at the opposite shifted positions do have some overlap, it is possible to just stitch those two images. But I generally get better results if I combine all three.

To complicate matters, these images are also created by combining different exposures to create final High Dynamic Range (HDR) image. So, in fact, I stitched three panoramas, each at a different exposure, in order to use Photomatix and create the final image. I always advise that the panoramic images at the same exposure be stitched first and then those multiple panoramic images, at different exposures, be combined using HDR software.
