20 cent coin

Description

Another photogrammetry test to prepare for a historical coin photoscan in the future. Any adhesive paste and/or anti-glare spray prohibited. That makes things quite difficult. Setup: OpenScanner (www.openscan.eu) in a light tent with no artificial lightsource, Sony Alpha 77 II, 2 chunks with 206 RAW images each, processed in lightroom (mainly noise reduction, contrast increase and cropping), Agisoft Metashape. The texture is striped at the chunk borders, perhaps re-uploading this in the future.
