Bloom effect like in blender.

How can I achieve blender-like bloom effect ?
Parameters are similar, but effect in unity is ugly..

 

If you don't like the look, it is possible to try write your own bloom effect.

Source code for the Post-processing Stack v2 is available if you just check the package folder when you have post processing installed. Maybe adjust a copy of the current bloom effect or make your own style bloom, for example downscale the image, blur it, then somehow apply the halo effect over the original frame so that it produces desired look.
