Final Answer:
Backscatter on a digital image can cause an artifact called a "halo."
Step-by-step explanation:
Backscatter and Halo Artifact:
Backscatter: Backscatter refers to the phenomenon where light is scattered in various directions due to interactions with particles or imperfections in the imaging environment. In photography, backscatter often occurs when using a flash in low-light conditions, causing illuminated particles (e.g., dust, water droplets) to reflect light back into the camera lens.
Halo Artifact: The result of backscatter in a digital image is often seen as a halo artifact around bright areas or light sources. This halo appears as a glowing or hazy ring around the illuminated object, degrading the overall image quality.
Understanding backscatter and its associated artifacts is crucial for photographers and image processing professionals.
