Firstly it is necessary to have a black light. These lamps are similar to neon lamps, but they give a specific light, also known as ultraviolet under which all objects with bright and fluorescent colors shine as if they were themselves a source of light. These lamps are often used in discos, in devices for testing money, etc. If you want to learn more about the black light, please click HERE and read the explanations and look at the photographs.
So, as a light source I used black light. My model wore a vibrant green color dress which under this illumination produced fantastic light effect. In order to successfully take this picture, I had to increase the ISO value to 3200, the aperture to a maximum (the widest opening), and of course I still had to extend the exposure time. It was little complicated because the model is supposed to stand absolutely still during the photographing. When I made the shot with which I was satisfied I opened a photo in photo editing program so I could slightly improve the exposure and eliminate the noise which is inevitable at this high ISO values. And this is the result that I got.
