This isn't a "normal" picture but instead a refractograph - I took the lens off my camera then shone a light at one of our crystal glasses. The pattern is the light that refracted through the glass and onto the sensor!

I'd seen someone who has spent far more time practicing this than I and his results are considerably better, but as an exercise for a few hours it was quite interesting.

Given how random the outcome was I'm not sure if I'll worry about doing it again though!

SOOC, not even a whiff of Photoshop!
