This is the second location used for a private IBL (Image Based Lighting) and Autodesk Maya project dealing with car renderings called Ibiza & Bridges. Werksbrücke West in Kelsterbach is a bridge only about 200m away from location number one (Sindlinger Mainbrücke). It is a private Road and Railroad bridge of the Industriepark Höchst near Frankfurt. Nowadays closed for public traffic it is accessible for pedestrians and ciclists only.
Measurements of the scenery were done on location using a single yardstick only.
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.
Due to the shining sun the shadow of the tripod is visible in the panorama.
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.
Post production consists of some color adaptations and preset filters only done with www.pixlr.com.
