Comparison of He-Ne Laser and City Lights

The file, LASER.JPG, contains a photograph of an 8-mW He-Ne laser pointed at the camera. The laser is in Provo, Utah, at night. The camera is across Utah Lake, several miles away. The laser light is so intense, compared to the city lights, that it caused blooming in the film. This is the diffuse red spot you can see in the photograph.
