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 rigid pole. Three 35-mm still cameras and one 16-mm real-time telecine camera were used to document the pre- and post-crash environment. Table 6 lists the position and lens used for each camera. The camera numbers in table 6 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 25-mm-wide black and yellow target tape were placed on the Chevrolet pickup truck for film data collection purposes.
