 Shadow blister effect

The shadow blister effect refers to a visual phenomenon that occurs in certain imaging contexts, particularly in photography and digital images. It manifests as irregular, distorted areas or "blisters" that appear on surfaces, often due to improper exposure, lighting conditions, or post-processing techniques. In more technical contexts, such as computer graphics or 3D rendering, the shadow blister effect can be associated with artifacts that occur when calculating shadows, leading to unrealistic or exaggerated shadow appearances on surfaces.
