Hello! I was wondering—can this method also be used to help recreate lighting scenes?

I suppose it depends on what you mean by "recreate lighting scenes".

While there are many ways to relight scenes, the (arguably) simplest approach would involve recovering (i) scene geometry (i.e., surface normals), and (ii) BRDF. That way, one can then approximate what the scene would then look like under arbitrary illumination conditions.*

In the context of photometric stereo, we get exactly these components: (i) a surface normal per point and (ii) the surface albedo. This information is enough to then relight the scene under different lighting conditions.

*(This however would not capture more complex light transport phenomena, like diffuse interreflections, or even shadows. But may be good enough for some applications.)
