What is Black Light Photography?
Black light photos are black and white images that explore dramatic contrasts of tone. The pictures are taken and digitally manipulated to having a higher contrast so the white and blacks of the image pop creating a silhouette of the subject being photographed. However, when digital editing didn't exist, black light photographs were made in the darkroom as photograms due to the exposure of light which also creates the contrasting effect that you can nowadays create on photoshop.
Keld Helmer-Petersen.
Helmer-Petersen was a leading photographer of his time and achieved international recognition when he was young. He is world famous for his early colour photographs from the 1940s, his tight modernist photographical compositions and his unique use of books as a particularly privileged way of exhibiting photographs. When working on Black Light, Helmer-Petersen used modern digital techniques to create his abstract black and white photographs with dramatic contrasts of tone. He created these images using both cameras and flat bed scanners to achieve the effects he was looking for.
