The goal of experimental photography is not the portrayal of reality but the exploration of the photographic possibilities and the effect of the interplay of light, aperture and shutter speed, intentional movement of the camera and blur and manipulation with image editing programs. Another technique of experimental photography is the double exposure. Thus, several levels of reality are captured in a picture. Similar to long exposures, the individual exposures blend into each other. The motifs often become transparent. Double exposures relate people and / or objects to each other.
