One of the features of the technical camera is the ability to shift in both the horizontal and vertical directions.
The shift in the vertical is used to maintain parallel lines in buildings when you cannot shoot from the mid point of the building. Difficult when it is several stories high.
But also you can shift horizontally to stitch a wide image. This is different to using a panorama head because the camera does not rotate and hence the view does not become distorted. When joining the images in Photoshop they are just aligned on top of each other and blended together.
This was shot with a 32mm Rodenstock lens on the Cambo Wide.
It is showing a very wide angle which I guess you might need to visit the site to see how this would have been difficult any other way.
