Light writing, or "sparklers in the night" can be a fun and unpredictable experience for all involved.  The idea for making letters instead of just the usual sparkler shake and run came from the four ladies you see pictured here.  It takes coordination to move your hands and not  the rest of your body, but it is only for 3.1 seconds.  So as you can see, it turns out well and this was the first try.  The picture below has the same META data except the seconds were increased to 6 seconds.  There are note worthy differences in the two photos.  Pick your preference and have fun!  Be sure to have a flame throwing lighter in the hands of a responsible adult.  Small flame lighters tend to give blisters to the adults using them.  META Description: Nikon D90  f/25 3.1 ISO 500 +5 exposure compensation Speedlight SB-900
