I like bicycling and photography, especially when I can do them both together ! In the Fernleigh Tunnel on the cycle track near Adamstown there is a long row (c. 250metres) of sodium lights that casts a yellow-orange glow to the eye.
This magically shifts toward red on a long exposure in my Sony “bloggie” camera. To make use of this effect I use a moving subject that is travelling approximately the same speed as the camera ( my bike, usually, or a cyclist in front of me )
This gives a distorted but recognisable image, compared with the near tunnel walls or ground that are blurred by the long exposure – usually 1-5 seconds as the camera tries to gather enough light to make the exposure. In the middle of the tunnel the redness is strongest, while near each end it is mixed with the daylight.
The process should work with any digital camera with “flash off”, and any bike with a bit of shine – my favourite bike for this is my Gazelle because it has lots of shiny bits and a distinctively shaped front end :
This technique works well with self portraits too if you have a camera with lens and display on the same side, such as the “bloggie”. The strip “header” image of this blog was also made in the tunnel.
Here is a more abstract view of my old speedwell, to finish – I will add that I am careful to see that there is nothing coming in the opposite direction when doing “bloggie lo-lite” photography ! :
