Arkadiusz, what I find so amazing and... elegant about ray-tracing is that the depth of field is simulated in a physically plausible way across all engines, and it works really similar to the real-world photography indeed. This universality across media is just inspiring. :)
Should be used with caution, as it's quite a *spicy* effect for sure, it would better fit the overall aesthetics of the shot, but yeah I share that sentiment for sure :)
Love your tutorials Gleb. Looking forward to finishing the excellent photoscanning and night lighting courses when I have time. Keep up the good work :)
Not sure about the actual physics of the swirling bokeh (I think the specific look of Helios 44-2 is the result of the error in the manufacturing process), but It's uncanny how the effect made with a simple cutout in Blender resembles the real vintage lenses. At least to my eye.
Of course, alongside with the true anamorphic optics simulations! Btw, Jack Toth does some really interesting experiments in this field, with Blender: www.youtube.com/@JackToth
Geofrey, don't expect too much though, it's a seasoning that doesn't *always* make it better) Start by checking the RUclips videos where the lenses with the swirly or weird bokeh are showcased, the reviews specifically, like this one: ruclips.net/video/wgSp9-AMXOk/видео.html&ab_channel=PavSZ
i revisited this video, as one does with nice things. i have that B3dsdf toolkit. Combining that with a switch group i made of various grunge and dirt textures. i put those through a mixer. ive got so many bokeh shape/ texture options i have to change my pants. way more options than is useful or legal i think
I think you could easily mitigate the Bokeh and Aperature issue with a driver from the camera aperature driving the bokeh shape scale. My assumption is that would solve the issues. Plus if some experimentation found that distance from the camera origin positively affected the bokeh fringe and quality, you could link the same aperature driver to the local z axiz of the bokeh shape plane! I haven't tested this, but it seemes like it would in my head! I might try it. If I do, I can post how I did it.
That's a great idea, Owen, I think the driver affecting the bokeh object scale would work (not sure about animating it though, but probably would work as well?). Linking it to the distance from the camera (z axis) - also an interesting thought. Please share your results if you test this!
@@GlebAlexandrov I will, and I'll credit you and shout you out to make sure people know where the idea came from. I might drop William Landgrens stuff in too cuz hes got a similar setup, but in Add-on form. I love the new lighing content, its gonna help so many new people getting into blender or looking to level up!
This is a great and simple solution. I personally use photographers addon for custom bokeh when I need this kind of an aesthetics, but the price you are paying with that is much longer render times. Can you tell us what are the render times with this technique applied, compared without the bokeh plane? Does this add more to the render times?
The techniques used here in Blender are similar to the way a DoP will shim cutout filters with custom shapes near the rear/mount of the lens. The same effect can be done on set, in-camera with a mattebox filter. Going even deeper with this concept conceptually, netting is often used in the back of a lens to act as negative fill through the optics, condensing the light based on the material density of the fabric. It would be fascinating to see what you could pull off in Blender for a similar effect, or even to try and replicate lens diffusion (i.e., Black Promist, Tiffen Black Diffusion, etc.)
"netting is often used in the back of a lens to act as negative fill through the optics, condensing the light based on the material density of the fabric" - oh that sounds interesting, I've never heard about it. Would you mind pointing me out in this direction by sharing a link perhaps? p.s. As for imitating the Black Promist filter etc in Blender, I think Jack Toth came closest to it, with his anamorphic lens simulations (which also includes the 'naturally' occurring lens flares and so on): www.youtube.com/@JackToth
@@GlebAlexandrov Here’s an example of how it’s done, just keep in mind black netting will create the most contrasted, tonal look ruclips.net/user/shortsaZIQOX6TJKk?feature=share
I tried a similar method, but I had weird results in animation when the camera moves with motion blur. do you notice something unexpected in that case or was I wrong with my settings?
O, that's a question for a dissertation :D Or for a series of videos. Matching the live action lighting boils down to a few things: * Matching the lighting via capturing a spherical hdri on location (for example. that's just one possible technique) * Matching the rgb color primaries of the live footage & Blender rendering (via a color checker, X-Rite ColorChecker Passport or other) * Matching the white balance (temperature and tint) across the media * Make the 3d geometry cast shadows onto the live footage (via shadow catchers and other tricks) * Make sure you converted the live action footage to a linear scene-referred .exr first (so all matching is happening in the scene-referred 32-bit space so to speak. That's the part that is hardest to wrap your head around, but it's the most fruitful as well) These 5 things are probably most important when matching live action with 3d. :)
@@GlebAlexandrov that will be the best gift of my life if you can give us series of video to match live action ...but thanks for the tip...please try if you can thanks in advance ...
Amazing Gleb, but how would one create the anamorphic lens streaks in camera, think JJ Abrams/Star trek. Not really bokeh related, but camera related. Like the renders from technouveau linked here. Would love a tutorial on this!! www.youtube.com/@technouveau9584
I remember you showing this trick many blender versions ago. I wonder if we add a light guide right in front of. Normally helps with interiors, could it help with this to make it brighter?
Rombout, what do you mean by the light guide? I don't think I got it :) Generally the way I make it brighter after adding the bokeh cutout is by amplifying the white point in the color ramp node following the bokeh texture (to 5, 8, whatever).
The warping effect is (or should be) more pronounced near the edges, you're right. That being said, depending on the 'amount' of the warping, the effect could be quite pronounced near the central portion of the image too. In other words, it's a feature, not a bug, at least as I see it. p.s. This video, "This Weird Lens Is The Swirly Bokeh Emperor" has some good examples: ruclips.net/video/E8glc_jdNBw/видео.html&ab_channel=MathieuStern
I mean - it makes sense if you know how the depth of field is done in cycles.
Thumbs up for putting it to use.

I always waiting for your new videos, I grew up watching your videos, you're one of the blender legends
I'm not THAT old though... Am I? :0
@@GlebAlexandrov LOL, I watch your tutorial since I was in high school 9 years ago
Wow! As a photographer this amazes me because this works with real cameras! had no idea Cycles was that thorough with optics simulation
I was simply shocked when learning that it works in path-traced render engines the same way basically as it works in real optics.
unbelievable... never found someone like u who uses blender to a professional level.. your creativity is amazing
Such a beautiful result! You can really make you render stand out with this.
Should be used with caution, as it's quite a *spicy* effect for sure, it would better fit the overall aesthetics of the shot, but yeah I share that sentiment for sure :)
Great tutorial on custom bokeh's, thanks. FYI, if you want to animate your camera don't forget to parent your bokeh images to the camera!
Oh yes for sure, that's a good tip actually! Fortunately that's really easy to do, shouldn't be much of a problem.
Love your tutorials Gleb. Looking forward to finishing the excellent photoscanning and night lighting courses when I have time. Keep up the good work :)
It seems that the content did pile up a bit, hehe. Let me know which one of the two was smoother to watch. I crave feedback in any form.
Following your tutorials
is always a pleasure and a source for creativity. And as you know you do really deserve the title of "Genius of the light".
thanks a lot. I need to play around with the swirling effect, didn't know about that :)

Turbo nice, thanks Gleb! Great and simple technique \m/
I like this type of the techniques that are both a) simple, b) alter the vibe quite dramatically and c) are based on a real photographic technique!
Your tutorials always leave a smile on my face, thank you for sharing this mesmerizing technique. :D
Great technique. I still wish that stuff like this (custom bokeh shape, bokeh density, etc) will be hard coded and optimised some day
Of course, alongside with the true anamorphic optics simulations!

I thought the way you got the swirl was interesting, but shouldn't it effect the outer edges, not the centre?

Yes. Maybe except the last bit about fisheye polinomial lens, correct me if I'm wrong though.
Didnt 3.5 stable just released? There no problem running on my weakass 2015 Processor component during the alpha why bother using 3.3. . .
