halobeeld
Halobeeld is a Dutch term used in optics, photography and astronomy to refer to an image that contains a halo surrounding a bright light source. In natural observation, halobeeld describes atmospheric halos around the sun or moon, such as a corona, arc, or ring created by interaction with ice crystals in the atmosphere. In imaging and photography, halobeeld can also denote a visual artifact where bright highlights generate a ring, glow, or halo around the light due to lens effects, diffraction, internal reflections, or sensor blooming.
Etymology and usage: The word combines hal(o) meaning halo with beeld meaning image or depiction. In Dutch-language
Causes and variations: Atmospheric haloes arise from light refraction and diffraction on microscopic ice crystals, producing
Applications and interpretation: Halobeeld serves as a descriptive term in education and communication about optical phenomena.
