Master photographer, please look, help me analyze how this photo is polished. What direction is the light? Was it filmed?

If you want to get a similar effect, you can use a front decorative light with a small aperture (that is, a narrow light source for the ceiling light) to get a satisfactory effect.

However, according to your pictures, the shapes of the flashes are similar, which should have been processed by photoshop in the later period. Relatively speaking, the ornaments under the solid color background can achieve satisfactory results by post-processing with photoshop. The requirements for pre-lighting are not high.
