The 360° panorama was shot with a Canos EOS D60 with a Walimex 8mm fish eye lens. The panorama contains of eight bracketing rows (zenith, five equator shots, nadir and offshot) consisting of seven different exposures each (2 EV steps). Stiching was done with PTGui 12.7.

The backplate for this shot was also taken with the 8 mm Walimax fish eye lens just a few centimeters above the ground. Measured parameters such as the distance to the IBL location were tranfered to Maya and slightly tweaked to fit the photography.

Light balancing was done using two test spheres at later position of the rendered car, one with a chrome shader fully refective, the other with a pure diffuse white material.

A second light source was necessary to slightly increase the shadow of the car. In addition to the IBL light dome a directional light was used shining from the right side of the scenery.
