As one of my assignments during my photography studies, we have to play with light... Gosh, never expected to become so obsessed with light.
I now have multiple bulb-shaped bottles filled with all sorts of seemingly toxic mixes of soap and UV powder. For this image I got a wire and hung it on the wall, giving it a swing.
It took me a while to figure out the right exposure time to get an image like this. But it gave me a lot of "failed" and blurry shots. Eventually, I decided to just blend them together in Photoshop instead.
