Capturing glossy surfaces with Agisoft Metashape

[EdenCairns]

Has anyone managed to capture surfaces that have a more glossy texture with Metashape? While details on matte surfaces look fine, more glossy areas with less surface detail are coming out looking like melted wax.

Hi Eden,

Yes, reflective and very glossy surfaces are not well-captured by photogrammetry; it's probably best to focus on a more matte object, as you say. For a very reflective or transparent object you could try coating the surface with a very fine dust (chalk or soot), but that would of course (a) contaminate the object, possibly undesirable for heritage objects; (b) make a mess if you're doing this at home. Others may have better suggestions!

There's various techniques to counter this as @gabrielbodard says - sprays, filters and other means. However, I would stick with something easier if you're learning. Example spray https://europac3d.com/3d-scanners/aesub-blue-3d-scanning-spray/

I'm having a different problem but thought I would put it in here rather than start a new issue. I cannot add photos into the software, whenever I try a pop-up box appears saying 'Can't load photos'. The photos are all jpgs, and I even tried taking the photos on a different device but still no luck. I can successfully upload an image I downloaded from the internet as a test though so I'm not sure what the problem could be. Any advice?

@molmay that's usually permissions errors in metashape, are you loading from external drive, usb or your local machine? You don't say whether you are on windows or another OS. Try changing the location from where you are loading the images from, and maybe share a screengrab of you interface when it says no?
