I have eyes shut because they reflect and easily move when someone takes pictures in different directions. This was pictured outside on cloudy day, best when there is no hard shadows. Once I tried take pictures on interior and light on my forehead made hole on 3d-model

Easy to try, it might take few trys to work. Rough materials like bread or brick wall are easier to make, glowing, transparent or single colored things usually don't work. Photogrammetry programs can only make what they see, if I only picture my head from upside, model doesn't have nostrils.

Photogrammetry testing. I used 3dfzephyr free version. You can use even ancient cameras to make photogrammetry models, decent computer required. There is also some apps for phone for photogrammetry, I haven't tested them.
