This was such a good video. Is there any benefit to polarization on the lens, without polarizing the light?

[@rileyb3d]

You will definitely see a benefit even with just a lens filter. If you're only going for one end of things, I'd start here as it's also cheaper.

Great video, and great explanation of cross-polarization. As far as software goes, there are a few options for constructing photogrammetry scans. A neat one is Meshroom, which has a Blender plugin and is open source.

[@rileyb3d]

Great point! I'll have to check out that plugin. I cut this bit from the script due to time. It could also apply to Meshroom: "Polycam excels in convenience and mobility. In the rare case I get something unexpected happening with my scan, and I need more hands on tools to troubleshoot, I might jump into Reality Capture as my backup. This will give me more debugging options if I need them, but these days I’ll use Polycam for most scenarios."

[@user-ei3wi9re6o]

I have a question. The polarizer is already composed of two polarizers. Rotating and crossing can effectively remove the highlights. Why do you need to control the direction of the light source?

[@OverJumpRally]

Great video! I love the CG part, took me a moment to realize it wasn't real! I guess you also scanned your equipment?

[@josema9317]

You can save a lot of money on your setup, if you buy a foldio 3 lightbox and turntable. By the other hand, with an entry level camera like a nikon d5600 will be more than good enough.

[@rileyb3d]

I haven’t tried this light box but it looks good for small objects! Could be a good desktop option. Also, definitely yes on different camera options. There are many that could work well.

[@josema9317]

[@Adam-dr1rs]

Which method was used to create the into/outro sequences? I’m guessing not the basic setup?

[@wukerplank]

Hum, seems my comment got lost 🤔 Anyway: I appreciate the amount of work you put into this video and the quality you produced! It was a pleasure to watch 😊

[@rbrown2925]

Fabulous content, thanks. One question: the link to the polarizer for the camera lens says it’s circularly polarized but I got the impression that linear was the way to go based on the video graphic. Is the link correct, the graphic “not particularly accurate,” or am I missing something? I’d bet the middle case because two linear polarizers at right angles should block all light, at least in theory, but I’m no pro. Thanks!

[@rileyb3d]

Excellent question. So for both the linear and circular polarizer, the light is being polarized in a linear fashion as demonstrated here in the visuals. For simplicity in the tutorial I didn't get into it, but the difference is the circular polarizer has an additional layer called a quarter-wave plate to make it work with modern mirrored cameras. The difference is negligible IMO, but still. Apparently a linear polarizer will mess with a mirrored camera's metering and autofocus. Long story short, you're safe with a circular polarizer no matter what camera you use, so that's why I recommended it here. It's a safe purchase for everyone. Again, the light is linearly polarized as shown in the video, it just has an additional layer to work with mirror cameras. It will also work with mirrorless. If you have a mirrorless camera, metering and autofocus work directly off the sensor, so light isn't mirrored and bounced around to different locations in the body. A linear polarizer would work fine in this case.

@@rbrown2925 Just read my response and I'm wordy lol. TLDR go for circular in most cases.

Is Polycam free to export your model, though?? I recently got my first ever iPhone (11)and have used Photo Carch for some pretty sweet results entirely oh my phone with it's megre 12MP camera

[@rileyb3d]

You’re right, I believe their export options are limited until you pay. I can check out photo catch. Though, desktop uploading is a must-have for me.
