HIGH-SPEED PHOTOGRAPHY

    A total of nine high-speed cameras were used to record the side-impact collision. All high-speed cameras were loaded with Kodak color daylight film 2253. The cameras operated at 500 frames/s and were positioned for best viewing of the contact between the Chevrolet C2500 and the Valmont Industries slip away lighting standard. Three 35-mm still cameras and one 16-mm real-time telecine camera were used to document the pre- and post-crash environment. Table 7 lists the position and lens used for each camera. The camera numbers in table 7 are shown in figure 6. The interior of the driver door was painted flat white for better onboard camera image quality.

Black-and-yellow circular targets, and black-and-yellow target tape 25 mm wide were placed on the Chevrolet pickup truck for film data collection purposes. Circular targets and target tape were placed on the vehicle for certain vehicle measurements and for film analysis. The 25-mm tape was placed on the driver side of the vehicle at five levels or elevations referenced from the ground. The levels included:
