Via Beautiful/Decay.
What looks like a beautiful abstract watercolor painting is something else entirely. Cheeky artist Ross Sonnenberg lets out his inner wild child and lights fireworks in his darkroom to create these intensely colorful one-off photograms. Using photographic paper, gel, sand and light, he sets up the experiment and lets chance take it’s effect on the paper. Interestingly enough, the images he creates resemble galaxies, or close up views of our solar system. Full of different layers and textures, his work definitely looks celestial, and featuring a big bang of some kind. Sonnenberg writes:
I have always been fascinated by the planets and stars, looking through telescopes and wondering what these far off places might look like. With this series I have tried to create imaginary solar systems and super novas using different materials, and fireworks for my light source to make one-of-a-kind camera less images directly onto color and black and white photographic paper. Like the darkness in outer space, I work in the dark to create images that mimic the interstellar places that I always dreamed about going to as a kid. (Source)
His past two series featured the experiment on different scales – Color Bang features the technique on a smaller scale, using pieces that are quite small, and Long Bang involves using larger pieces of paper and stronger fireworks. Have a look at his technique in the video above, and if you are feeling bold, you could try it for yourself.

He might want to try this in a garage that’s not full of flammable stuff. I was cringing through each of the sessions.
