@randy I think this is the video we were just looking for on the Patreon Zoom: Alfie Vaughn showcase [How to Get Photorealistic Depth of Field with Nuke's Bokeh Node with @AlfieVaughan] and follow up https://youtu.be/iBj_k7KcjD8?si=-j0tmQgZe-UpnULX About the 3rd party lens kernels fo…

oh damn. I need this in houdini :joy::heart: damn

Love that… giving me Lentil vibes

[image] andy_dill: I like that video because it demystifies what often feels like a blanket “nuke does it better” statement around defocus and PG Bokeh. We almost have that in flame… When you say “almost”, do you mean because physical defocus almost works but doesn’t actually work? Or is ther…

“Almost” because we have the same tools but there may be specific use cases where Nuke does indeed do it better. All of those nodes, barring on some level PG Bokeh, are in flame. Blur does both regular and lens blurs, so that’s covered, there’s a convolve filter in the sapphire set and in the defau…

Thought this might fit here, something I’m working on… lens_and_camera_demo_241203_1115.mp4 Google Drive file. But that “swirly bokeh”, I’m gonna have to try to implement that too!

What’s that “swirly bokeh”? I missed it.

It kinda looks like the bokeh kernel becomes more elliptical, the further from the center you get, in a radial way, and the kernel shape kinda changes further from the optical center. It seems that older low quality lenses have this effect. You can see it in the blender demo in a few places, try 5:…

Similar to the Deakinizer, no? Edit: actually only superficially it would appear. The deakinizer seems to be more of a radial direction blur outside the plane of focus in the center, as opposed to that intense swirling! The swirling’s neat for sure!

Never heard of a deakinizer lens before, thanks for posting that! And I think you’re right, it looks like some settings of those lenses make that specific "swirly bokeh"effect, bit they clearly do more. Interesting! [Deakinizer]
