If you do a picture like this with a flashlight or some other focussed light you get very distinct edges like a spirograph. With glowsticks, there isn’t a point of light, it is a stick, so the picture looks blurry, but it isn’t. It is more like a light painting with a paint roller instead of a fine brush.
I liked the way this picture looked, even though it doesn’t have the fine points that these pictures usually display. The brighter lights are where there are bubbles in the glowstick so there are blank areas next to bright ones that make it look like a point of light moving instead of a band.
