Light painting, night photography

Following last weeks attempts at light-painting I browsed around a bit more on the subject. Apart from forgetting the vital connector-thingy to my tripod, the main trouble I had was actually focusing on the subject. See... its dark... so I upped f-stops and made a wild guess. Apparently the simple way of doing night-time focusing is simply to buy a cheap laser and highlight the subject. Since autofocus works on some sort of light-phasing principle it can use this small beam to automagically focus - no need for flashlights.

Stumbling along I also found the group Light Painted Tunnels at Flickr, looks neat! Heres the Flickriver link
