In this video I present my photogrammetry setup I use for indoor 3D props scanning.
My intention was to show not just what, but also why I use certain things.
I want you to learn from mistakes I made while building this setup so you can learn from them and build a better one.
I really hope this will give you get better understanding of camera setting, light behaviour and Depth of Field dependencies so you can use them in your advantage.
In details I show:
- inverse square rule for the light falloff
- Depth of Field dependencies
- short story of failures, lessons learnt and improvements introduced to make this setup working
- complete list of photogrammetry setup for 3D prop scanning
- how to finally connect everything together to start the scanning process
Since its a long one, I really hope it was worth the effort and someone finds it useful and helpful.
If you like it and want to see even more content like this one, please subscribe to my channel and leave the thumbs up.
Big thanks who did it already as it really helps me to move forward.
Stay safe and till the next one
Cheers!

- Since some of you ask me about equiment details, I pinned it to the top comment but here it is for those who still missed it :)
The list is at [53:17] but I put it down here with reference links, mostly to the British Amazon. Gonna PIN this comment as you are not the first person who asked and EDIT it if I find that I missed something
- Camera - Canon 80D - Considering to switch it to Canon90D or R when this one dies
- Lens: Canon 18-135mm for large props, Canon Macro 105mm for small props.
- Hoya HD Gold Circular Polarisation filter - you need to pick the size correct for your lens diameter

- X-Rite ColorChecker Passport - I suggest to purchase an original one from X-Rite
(https://amzn.to/3zLKY7t)
- Aluminium Manfrotto 190Go! Tripod with twisted locks, no clips as clips are much heavier. Carboon version is about 300 lighter and honestly.. still not sure if it is worth to switch. If I have a choice and a lot of money, I would probably pick the carboon one. But for props scanning it can be any which is stable enough and designed to hold the weight

Manfrotto XPRO Ball Head with 200PL Quick Release. I used the RC2 but it is out of stock and isnt produced anymore. This one tho can hold the flashed angled.

If you plan to shot a lot of weirdly angled images I would consider the one with Arca Swiss mount.
