This photo is a composite of several images to create a panorama image of the sales floor. This event took place at the Porsche of Irvine dealership in Irvine, California.
A similar image could have been achieved by using a very wide angle lens, but it would have created much more distortion, especially at the edges of the image. The composite process is more labor intensive, when taking the photos and in post production, but it creates a more pleasing image, and kinder to the people at the left and right edges.
