Photogrammetry is great with textured, consistently lit, opaque objects.

Blank white plaster, less so. You really want some kind of microtexture to grab on to for it to be anywhere close to a structured light scanner. That may mean you want a macro lens and a thousand exposures because you're grabbing on to microscopic surface roughness or dust. Not necessarily easy to do surreptitiously.

Yes they are different things and photogrammetry isn't a replacement for a "real" 3d scanner. But this is about museums which largely aren't unlit plain white surfaces. Getting models of museum objects is generally doable by anyone without thousands in specialised equipment. Taking a video or pictures is a lot less weird than pulling out any scanner.
Do you have any software recommendations? I tried a few photogrammetry apps to capture small items (e.g., keycaps) and bigger ones (e.g., my face) but the results were never good enough. Ideally, I would like to open such models in Fusion, make a few edits, and 3D print them.
