what's the central aura of light in a bright source called along with the diffraction spikes surrounding it colored differently?
you can typically see it with stars, the sun or virtually any bright source of light.

It's just called diffraction spikes. I guess you could call the source a point source, I don't believe there is a word that encapsulates them both nor a need for one.

Nah man, there has to be terminology for the type of optical features the eye perceives.

lense flare? lol?

The sun.

>>9111079
The sun is the source of the light. However, any focused sources of light would produce the same optical phenomena. The sun's disk is hidden by the overwhelming, centralized and luminous light.

If you're talking about that hazy glow you get from bright sources that makes it unseeable, That'd be the bloom.
>>
>>9111085
You're fucking retarded.
The sun's disk is hidden by the luminous light produced by it. The centralized ball of light is not unique to the sun.

Those are called "street lamps."

Are you sure? I thought bloom was like a lighting effect of the surroundings.

No, bloom is entirely post-processing in computer graphics. It has nothing to do with the world it's in other than how bright the thing it's looking at is. Imagine like looking at a blurry picture on top of another picture, but where light colors are more opaque than dark colors.

Bloom exists on both light sources and things which light has bounced off of, such as a car's reflection of the sun. The bloom would not be shaped with the car's surface/normals though, as the bloom happens in the camera.

I see. But I still can't find accurate, realistic rendering of the sun's own bloom for some reason. Google searches only ever give me dumb shit such as this which lead me to believing otherwise.

Its chromatic aberration and overexposure, isn't it?
