Figure 5 - Higher resolution photograph (219k) at 1000ft of high beam headlight and off-axis laser

1000ft 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 - stepped down to 1250 ASA. Pentax MV1 SLR 50mm Lens with auto-shutter timing. Angular width of image is approx. 35 degrees.

Comments: The now faint green laser pointer's beam is visible at upper-mid-left of center, near the top of the highway reflection stick in the foreground of the image. This exposure overstates the headlight's glare. To the naked-eye, the green "dot" of the laser emitter was visible next to the headlight. In this image, the high beam headlight's glare overwhelms the laser pointer's beam. The pointer's beam is faintly visible to the left of the headlight. At 1000ft, the green laser pointer beam was about 12 inches to the left and 12 inches above the camera, crossing in front of the camera.

The green laser pointer was stationed two feet to the photographic right of a car headlight. The car's second headlight was opaqued with masking.
