Why doesn't the alpha glow effect work?

Glow effects simulate the characteristics of lenses that suffer from light leakage due to high dynamic range. In photography, most cameras are set to use the average metering algorithm. The camera will analyze the picture and take the average exposure as the midpoint. Anything outside the dynamic range of the camera is either underexposed or overexposed. Due to the physical characteristics of camera lens, overexposure will penetrate into the image. If you stare at a very bright light source, it will emit that kind of flashing halo or white light. This article will review the process of how to produce these auras and examine some techniques of mixed results. Glow effect simulates the lens characteristics of light divergence in dynamic range. In photography, most cameras use the average calculation algorithm. The camera will analyze the frame and take the average exposure as the midpoint. Any image outside the dynamic range of the camera is either underexposed or overexposed. Due to the physical characteristics of the camera lens, the overexposed part can penetrate into the image and emit glow or milky light, just like staring at a very bright light source. This paper will review the process of how to produce these halos and check the results of some technology mixing.
