Selective Bloom
A bloom post-processing effect is a visual enhancement technique commonly used in computer graphics and video games to simulate the appearance of bright objects. This is a specific case of the bloom effect where specific objects are selected to which the bloom is applied to. This is in contrast to the general bloom effect where all objects in the scene are considered.
The bloom effect works by extracting the high-intensity portions of the image and spreading their luminance values to the surrounding pixels. This process mimics the way our eyes perceive bright light sources, which often causes a "bleeding" effect or a halo of light. By replicating this phenomenon, the bloom effect adds a sense of realism and cinematic quality to the rendered scene.
