This is the triple-exposure I mentioned on a Pentax-users mailing
list 'cause I was so pleased I'd gotten away with it. I'm going
to try again later, using a flash to illuminate the street a little
more, which should allow me to expose the traffic light itself a
bit less. The idea was to get the traffic lights with all three
colours lit. Why? Well, it seemed like a good idea at the time!
This was taken with a Pentax H3 (a camera older than I am), a Vivitar
135mm f/2.8 lens, and Kodak Royal Gold 400 film, using three exposures
of 4 seconds each at f/16.
The artistic composition of the shot isn't great, but hey, it was
more a technique experiment than anything else. I wanted to try a
trick I'd read about. :-)
