Outdoor Photogrammetry Surface Scanning for Materials with a Flash

#photogrammetry #scanning #flash #tutorial #materials #photography In this video I present a ring flash based photogrammetry setup for outdoor materials scanning. The idea for this one came after someone asked what the hell is this thing, after seeing the ring flash setup. I start with some theory, move into details and finish with 2 tricky examples. Hope someone finds it useful. If you like it and want to see even more content like this one, please subscribe to my channel, share it and leave the thumbs up.
