Higher resolution photograph (60k) at 500ft of low beam headlight and on-axis laser at 1 second exposure

500ft low beam headlight on-axis laser 1 sec. exposure

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

Comments: This image is identical to the 500ft low beam headlight on-axis laser view, except the exposure time is longer. The camera is looking directly down the optical axis of the green laser beam. The green laser glare overwhelms the car headlight. At this distance, the beam diameter is about 4 1/2 inches. The glare effect photographed here is overstates what was seen with the naked-eye.

The green laser was stationed two feet to the photographic right of a car headlight. The car's second headlight was opaqued with masking. This image is the true orientation of the photograph. The thumbnail of this image is rotated 90 degrees.

This image is cropped to eliminate a large scratch on the film negative.
