    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.

      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."

    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.

      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.

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

    • @rileyb3d
      @rileyb3d  Рік тому +1

      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.

    I am recently trying to decide what camera I should choose. Do you think it will make a big difference between the Sony A7III and the A7RIII?
    Of course more megapixels, but I heard that not only that matters.
    Currently my setup is an iphone 11pro and I would like to go deeper in this topic and also a camera for shooting pictures on vacation.

    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?

    I never succeeded in scanning a smooth surface with photo scanning, even if I cote an object with smooth cover of scan spray, the model surface is always rigid up to a certain degree, and then I have to smooth it, which makes it less sharp. Have you ever successfully scanned with a camera and got a smooth result without having to smooth it with a software? all your scans are objects with a rigid surface so let me know if you did it and how. Thanks

    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
      @rileyb3d  Рік тому +1

      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.

    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
      @rileyb3d  Рік тому

      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.
