The reason to have an SLR at Guy Fawkes
I love this effect! The best fun you can have with a sparkler!
Put your camera on a stable surface or tripod. Set your SLR to Tv mode (Canon) or S (Nikon) and set the shutter speed manually using the thumb dial. I set mine to 4 seconds.
ps if you don't have a camera with this function then ask a friend who does!
pps excuse the billowing pj trousers! I have been feeling poorly with an awful cold and living in them!
