I trying to get proper stars diffraction spikes, but i can't with zero blur on the whole image. Do you think you could improve settings to solve this?
A good start point could be:
- Decrease the minimal "blur" value (lower than 0.001). This should eliminate the global blur and help to sharpen rays.
- Add a "brightness threshold" setting. To dont apply glare (spikes, here) on objects/pixels with a brightness < to the setting value. (In other words, apply glare to brightness higher the threshold only). We could boost values without affect background. This also contribute to reduce the "blurry background" (here the further and low magnitude stars).
- Add "rays thickness" (or rays widthness) setting, in percent of source size. Where 100% generates rays at the spot size (as the current generation is) and (e.g.) 15% generates less thicker rays, at 15% of the spot size, such you can see on the real shot below.
Here is an example of real shot spikes :
Now, my render without glare:
And same with glare, the best effect i can get:
As you can see, spikes are thicker it should be, and every stars in background are affected and blurried, so all the image details are lost.
Hope you can make something to improve glare feature.
Thanks.
