I'm working on a project using painting with light techniques. It looks a lot like strings, except they are made of light. This is an image showing a 1926 photograph of my grandmother and my aunt, who had a turbulent relationship with each other. They were tied to each other but sometimes it was a bit messy... and not so great for those around them.
HOW TO: Painting with light is done by setting your subject up in a completely dark space and then taking a light source and moving it around your subject while the camera is taking the picture. I used a laser pointer here and had a small flashlight shining onto the top center of the scene. Your camera must be on a tripod and the shutter speed is set very slow, like a minute or more, ISO at about 100. Because the shutter is open for a long time the camera will pick up all the movements you make with the light, creating lines wherever you move the light.
