Enjoy the outdoors this weekend!
For this shot I used the 'illuminated tent trick' - during a long-exposure, light the tent from within or just behind w a powerful light source to make the inner space glow - something to try out the next time you go camping.
I used an LED light-pen prototype I've been working on for all the colors here.
