Photogrammetry Setup for Indoor 3D Prop Scanning

Video Description

#photogrammetry #scanning #diy #photography #tutorial #turntable 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!

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 (https://amzn.to/3qktKLD) -ScanSpace Ar400 Ring Flash Polarisation Filter (https://scanspace.nz/) - 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 (https://amzn.to/3nbzgOD) 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. (https://amzn.to/34DDHv9) If you plan to shot a lot of weirdly angled images I would consider the one with Arca Swiss mount. - Monopod: Sirui P-326SR Carbon Fibre (https://amzn.to/3F63QiI) - Wimberley Plamp II PP-200 (https://amzn.to/3JQBInn) - Emart T-Shape Portable Background Backdrop Support Stand Kit 1.5M (5ft) Wide 2.6M (8.5ft) Height Adjustable Photo Backdrop Stand with 4 Spring Clamps (https://amzn.to/3tdtik7) - Godox XT32C Wireless Power-Control Flash Trigger Transmitter 2.4G Wireless X System 1/8000s HSS for Canon Cameras, Godox XTR-16 2.4G Wireless X-system (https://amzn.to/3zG19mI) + (https://amzn.to/3HWdZQZ) but I would replace it with PRO ST-III Plus 2.4GHz Radio Frequency TTL Flash Trigger with High-Speed Sync (https://amzn.to/3r41dcb) just pick the right for your camera type - 10 Pieces Adhesive Felt Sheets,Black Velvet Fabric - RIKO400/ Witstro AR400 400Ws Ring Flash https://amzn.to/3qaj6GU - Syrp Genie Mini II (https://amzn.to/3nbBTjt) - Turntable for Genie Mini - Nortex Mill Plain Black 100% Polyester Bi-Stretch (https://amzn.to/3raO5SO)
