The obligatory tree stump

Everyone who has ever done photogrammetry or 3D scanning seriously has one. Or several. This one is min.. scanned over and over again, reconstructed countless times, and repeatedly abused to test new workflows, lenses, cameras, and capture setups. The tree stump is to photogrammetry what a test cube is to 3D modeling: simple, brutally honest, and perfect for exposing every flaw in your pipeline. No tree stump in your collection means you have not been properly initiated yet... ;-) A new telephoto lens was tested here. No drone was used; instead, telephoto lenses captured the upper section in focus. 334 images at 24 MP, splatted with Brush at 4K.
