Low anamorphic flare

Hi!! I saw some tutorials about low anamorphic flare but i cant find the right solution for my scene. I want to see the glow of the windows, just a little bit. I tried with volumetric lighting but it greatly reduces rendering time. Can you help me in some way? Maybe i have to do it in post production with other softwers?


Think about it… Flare, glare are not caused by the scene itself, but are in camera effects. Imperfections caused by anomalies in/front/on lenses (ie. clarity, physical properties of glass & it’s surface: dirt, smudges, drops, particles…) or on sensor/film. Similar to what eyelashes and tears do to human vision.

Ok, I understand the physical characteristics of this phenomenon now. But I do not understand how to apply it to my video. Sorry for my bad explanation but I did not know how to describe it in English, I’m just trying to add an effect that maybe can give more realism to my scene.

I like to use after effects for that, just out of convenience, so I don’t have to render for a long time to see the effect and do small changes, but blender can do this inhouse with this:

This is a compositing node, not a shader node.

Really interesting node but compositing scares me, i need to train with it! How do you do it on after fx?

in afterFX

there is a glow effect in AfterFX, but for more control and buttonpushing do this:

*duplicate the layer
*use a really harsh curve on it to make the bright tones white and the non glaring and non-glowing midtones and dark tones all black
*duplicate base layer again
*use the luminance of the b/w layer (the one with the curves) as mask to only have the bright parts of the image left
*make a subcomp from the mask+masked-layer
*blur this subcomp
*overlay over original.

Woww nice detailed explanation!! I do not understand the last two points before the last one (*make a subcomp from the mask+masked-layer *blur this subcomp)

Have a look at this.
Keep in mind that an anamorphic flare should be coupled with an anamorphic stretch/dof (camera settings/depth of field/aperture/ratio - I believe 2) and possibly aspect. There is no way (that I can think of at least) of creating high quality flares using simple glare node, although I use it all the time for actual glare.

Edit: For this scene, I expect you would want glare. Anamorphic flares are for high end productions in certain scene styles (headlights or flashlight in the dark kinda stuff) and require extremely expensive (anamorphic) lenses.
