sorry for asking here but i cant seem to make it work, the moment i enable depth of field in the camera settings it just blurs everything even with the correct distance. the only way i got it to work is using an absurdly high fstop like 5k or something, but then its just a regular sharp image. thanks in advance

Hi does anyone know if there is a way to close down the aperture to to have a deeper depth of filed??

@zircron45 Ай бұрын

Many ways, you can just scale down the aperture as a good approximation. If you want you can reduce the amount of iterations on the screw modifier to change aperture blade count.

This is incredible interesing. Every month there is a blender tutorial where I think it's the best thing I have ever seen but you just topped all of them. I studied photography for 5 years and your video reminded me of many concepts I learned about. I'm currently in the process of copying what you do and seeing how it works myself and what I noticed is that I initially modelled the lens far too big, the first element was like 2.5m. So I looked up how large it should be and I believe 62.5mm should be the right size. But when I decreased the size I was unable to get a sharp image... maybe I made a mistake when downscaling that led to some clipping or something. Anyways, super interesting, I will try to use this in my next project :)

@zircron45 Ай бұрын

Heyo! This is a limitation we're aware of and it sucks, but blenders floating point errors increase as scale is reduced. The fastest solution is to just work with slightly larger scales HOWEVER there will be a solution when 4.2 is released, that being the ray portal node. In the meanwhile if you see two lenses intersecting their surface normals just separate them a bit.

@SamEmilio2 Ай бұрын

Dude this is amazing. There's very few tutorials for proper anamorphic lenses in Blender, but I think here you've proven that it HAS to have "physical" elements to the lens - to get the distortion to work as you show in the demo, it can't just have a lens distortion node thrown on top. Amazing stuff

@rzaman-gg6en Ай бұрын

Can’t wait for the tutorial for this! I’ve been trying it on my own but couldn’t get it working this good, maybe because I don’t do the diopter or something but I have no idea how to do that. I mainly want to use this because I don’t see any other way to get the anamorphic depth squeezing, or where it actually horizontally squeezes further away things rather than just having oval bokeh Keep up the good work!

@christopher- Ай бұрын

I struggled a lot with softness at first, no matter what i did i couldn't get a sharp enough image. I thought i had modeled the lenses well enough, but i suppose every tiny little defect accumulates and contributes to a blurry image. I finally got it to work when i followed the patent numbers exactly, instead of the image. Lens thickness and distance between lenses matter more than you think. Importing an image of the lens layout was not enough to get a satisfactory result for me. I did it by keeping the first surface at world origin, offsetting every lens by the precise cumulative distance from 0, adding together all the lens thicknesses and distances from the lenses before. I used an add-on called OptiCore, which is made specifically to create lenses like this. It can even make aspherical lenses, just by punching in numbers. I finally got it to work, and it's pretty damn satisfying to have a true lens like this available. Thanks for showing off this technique.

@zircron45 Ай бұрын

I heard about opticore recently! I am not using a diagram from the patents, i'm using a diagram from Bill Claff, the guy who runs photonstophotos. The patent diagrams are terrible ahaha Im glad you figured it out!

@christopher- Ай бұрын

@@zircron45 Right, yes, i did use the diagram from photonstophotos, but using that image, that was not accurate enough in my opinion, just doing it by eye. It's a lot easier to trust actual numbers, and there's a huge difference in sharpness/accuracy in my results now. So i can totally recommend doing it that way to anyone finding they don't get good enough lenses otherwise. I do get the appeal of softer lenses though, but it should be because you picked a soft lens as a reference, not because it was modeled poorly.

@zircron45 Ай бұрын

@@christopher- Ye, i'm 100% picking up what youre putting down. I used to model directly with the patent info but with the lack of efficient methods it took ages for me. I ended up finding photonstophotos and it saved me a ton of time so i stuck with it. Modeling with the numbers is entirely valid if not more so.

@Velepexon 20 күн бұрын

@@christopher- Hey, I just wanted to ask, using OptiCore here as well What units did you use when you added in the numbers, and what lens radius did you go with?

@christopher- 20 күн бұрын

@@Velepexon As far as i know, the patents are in mm, so that's what i used as well. I don't think the radius, as in the width, of the lens matters as much as long as the radius of the cut surfaces are correct, but it will affect the size of your completed lens. I'm not sure if the radius is talked about anywhere, so that's the only thing i used the layout image for. I scaled the image so at least one lens matched in terms of thickness, and then set the radius of all lenses to the corresponding ones on the image to get it at least close enough to the real thing. Since you can set the location of the lens in opticore, you shouldn't have to fiddle around with the image once you've got it set.
