Halation Halation is an optical phenomenon that occurs in photography when light passing through a transparent or translucent subject is scattered or reflected within the camera system, causing a halo or glow around bright areas in the resulting image. Halation is most commonly observed in backlit scenes or when photographing bright light sources, such as the sun or artificial lights. In traditional film photography, halation was often considered a technical flaw and was mitigated by using anti-halation backings on film or post-processing techniques. However, in certain artistic contexts, halation can be intentionally used for creative effect to enhance the mood or atmosphere of an image. |
