Generally for photogrammetry you want to aim for more diffuse lighting. Avoid direct light sources as they will cast shadows onto your subject that get baked into the texture. Cloudy days or light diffuser umbrellas are helpful.
There are methods for de-lighting, but itβs better to just capture without if possible.
Or if you want to get fancy you can build a capture rig to create intentional shadows and process them into texture normals with something like Substance.
