Figure 2 - Higher resolution photograph (200k) at 500ft of high beam headlight and off-axis laser

500ft high beam headlight off-axis laser

Distance 500ft (152 meters). Full moon night 1-25-2005. f/2 iris. 1600 speed film. Pentax MV1 ASA setting - "B" manual for 1 sec. Pentax MV1 SLR 50mm Lens with auto-shutter timing. Angular width of image is approx. 35 degrees.

Comments: This exposure overstates the headlight's glare. To the naked-eye, the green "dot" of the laser was visible next to the headlight. In this image, the high beam headlight's glare almost overwhelms the laser pointer's beam. The pointer's beam is faintly visible to the right of the headlight. At 500ft, the green laser pointer beam was about 8 inches to the right of the camera. The green laser was stationed two feet to the photographic right of a car headlight. The car's second headlight was opaqued with masking.
