Thanks everyone for the fantastic comments! I have seen the demand for the Filter I made for the Godox AR400 and am glad to announce that you can now buy it here: scanspace.nz/collections/frontpage/products/ring-flash-polarizer-mount

Please cover your make for the ring flash polarizer if you dont mind sharing. Love your channel, I'll be looking forward to more sweet photogrammetry tips tricks and feats of amazement.

Thanks for the quick explanation I'm going to scan my kid so he can 3D Print himself.

Nice work, mate. Really good approach!

WOW perfectly explained. hope to see more on the future

Congrats on the grant! I bought a couple of those flashes off your endorsement and they made all the difference, I just need to steal your 3d printed polarizer bracket now : )

I love the choice of footage when talking about knowing photogrammetry in practice

Great content! Just subscribed. And BTW, your voice makes me miss NZ heaps (lived there for a few years around the far north in Kaitaia, Kaikohe, and down in Auckland). I look forward to your future videos.

I've been using the void method for a couple of years now and it works great. I'm glad I don't have to clean my meshes or worry about it not getting captured anymore.

This is great stuff, thanks for sharing!

Great video! I have been doing photogrammetry for many years as a hobby and always avoiding photogrammetry in studio because of all the cleaning it involve. But with this strategy, I might give it a try!

very well done ! Velvet is a very good idea ...

I have been trying various methods with mixed results. I will give this a try. I am curious about the polarizing flash cover you briefly mentioned. Thanks for taking the time to share your setup.

Wow, this is amazing.

Thank you, this is very useful!

Hi Erik! Love your work. Would you recommend using a lightbox to shoot? I see you don't use one in this video.

Very nice pro tips here.

Great stuff Eric! Do you align the shots/angels using control points?

Hi Erik, Your video's are very informative. Thanks for the tips. May I ask when set up you use for larger objects? Still a ring flash?

very impressive!

hey erik awesome video and thanks for this. i am shooting a birds nest at the moment :) I have a question did you only use the ring light finally to shoot the object (i think the answer is yes)? i was maybe opting to buy 2 cob-led lights like the godox lights and put a filter in front maybe with a soft box around it. would you think this could work to light the scene in a polarized manner? thanks in advance. keep up the videos they are great

Hi Erik, can you share your plans for the 3D printed Flash polarizer( the .stl file)? Great video, I plan on trying your technique. Great work.

You Are The Boss!!!

Great video just subbed. Do you have any advice around using the technique in the video and applying it to a smaller object like a small coin. Any tips would be much appreciated.

Incredible !!! Great video, any advice to find a cable that connects DSLR to the Genie Mini so long? thank you for sharing...

Incredible... I'm curious if you can generate any reflection/metallness maps with this technique?

Hey Erik, Thank you so much for sharing this awesome video! Can you share some info and setup of the polarized filter light rig and where I can purchase them please?

brilliant!

Hey there awesome vid! RE Going from high topology scan mesh to low topo do you have any recommendations? I am not a modeller by trade :^)

Iconasys has photography turntables that can automatically capture up to 8,000 images per rotation. Iconasys photography software can also remove the background automatically from all the images. Has Agisoft Metashape integration too. Makes the whole process much easier and quicker.

Amazing work. How would you approach scaning a much smaller object? lets say 15mm diameter.

I'm confused. You kinda of skipped over the polarizing part. How did you acquire that polarized filter for your light. I've a polarize filter for my lens, but I'm not sure how to acquire or make a filter for the light. Can you elaborate a bit on that?

Brilliant video Erik and great results too! Could you show us how you’ve created your flash polarizer? Thanks! 👍

*Awesome*

Hello, thanks for the video! I do have a question though; if you are using camera settings that show no other light than the flash, what is the purpose of the softboxes? Just for filming this video, or do they also have a linear polarizing filter on them?

Hey man, absolutely insane work and great tutorial, fast and efficient. What polarizing filter are you using? I also live in New Zealand, I can't find polarizing sheet film anywhere and the Amazon sellers are dodgy at best..

I was wondering if you paint you background and stand/base with black paint the true black 3.0 that absorbed all the light if that would do a better trick then velvet? I will try on my side bit maybe you already try

This is awesome and I think there could be some interesting applications in healthcare. Are you able to accurately scale the rendered 3D objects to achieve a true 1:1 size? Perhaps by including a known scale reference in the images?

Perfect! thx

Hi Erik, I’m making a game on unreal and I’m getting inconsistent results mostly based on the dark edges and reality capture thinking that those edges are voids. Even when multiple angles show that it shouldn’t be. I also have alignment issues when I turn the object just like I would if it wasn’t shot in a void. I’m using a canon RP with a tamron 24-70mm cross polarized ring flash and circular polarizer. I use Lightroom to take out all the black and try to use contrast and black and white levels to eliminate the ring/edge of darkness furthest from flash but I get inconsistent results. Thank you for any advice you can offer!

WOW TAHNK YOUUUU!!!! AAAAAAA

What is the software you use that shows your passes and cloud of your object? Thank you!

Great video! What software do you use to import photos?

How do you combat DOF issues? Even shooting at f/10 I get falloff on smaller objects. Are there anytimps or tricks for that? Thanks!

Before I go and make my own setup, are there any glaring limitations? How does this affect metals or similarly shiny surfaces? I'm guessing that I'll only end up with the diffuse but if the material isn't diffuse enough, it'll just turn black. Am I well served with this setup for something like scuffed metal where there's almost no mirror reflection to it or would it be better to get some kind of dulling spray to solve that issue?

Hello, my kiwi brethren - Can you point me in the direction of the specific polarising sheet that you bought, please? Happy level 4, again..

I've been using a different ring flash with a polarizer I designed in cad but I noticed the flash only seems effective using the ETTL function, any reason why they could be? Manual seems to illuminate everything, even the duvytene

Hey, where can I get the polariser for the lgiht?

Would this work with a diffused/cloudy day as light source, and a polarizing filter on lense instead?

Where can I find information on how to properly set-up Geine Mini II with the camera to use it as an automatic turntable?

nice tutorial! I'd just like to know if you can scan the apple just as well if you shot your images orbiting around apple with the camera mounted ring light as opposed to the apple turning on a turntable like you did here.

Hello. Do you do any shadow or highlight corrections with this type of setup? I have copied the majority of your setup an I'm an making great models so far.

So this is working amazing on my phone, but as soon as I transfer the RAW .DNG files over, everything is exposed and I can clearly see the velvet and black pedestal that were otherwise purely invisible. Do I just batch process them once more to ensure they aren’t there when going into something like Metashape?

What about if the object has black color? How you would change the black background?

Very nice, informative and fun to watch video Erik :), thanks for sharing.. of course +1 sub from me :D

hello if i want to have better 3d model quality do i need a lot of megapixels or a higher resolution ? please help me

How would you photograph something long and skinny, like a bone?

What do you recommend when scanning a dark object? A white background?

wonder if 80Ws flash in darkened room would suffice.

Edit: spoke too soon. You're able to rotate the object instead of the camera because of the black background. Do you think that having a background with a specific pattern might actually /help/ the software detect features and track camera position?

👍👍👍

Any info on that polarisation film holder for your flash? Can I buy like 50 of them?

Where did you get a big polarizer for the light?

Did you mention which photogrammetry software is used ??

Allow me to add my voice to the many folks commenting on this excellent video requesting details on the LED source light polarizer. Thanks.

What software do you use for the reconstruction?

Please tell me the software you are using!

What about using a ring LED and not the $500 flash? Will polarization still work?

You need to get a patent on that magnetic polarizer if you haven't already.

I dare you to try this void setup for scanning old medieval codex books 😂 Also black background? Yea, from my experience, that is a no no because i am using 3D Zephyr and their masking tool. Only gray works for me.

I personally think you needs little better title
