About photography: How were the light spots in this photo taken?

What I hate the most is people like me on the first floor who pretend to understand and mislead others. First of all, the problem with shooting like this is not the problem of the shooting, but the problem of the scene. The formation of light spots is not lens flare, but because of reflections in the background. Objects, such as water surface, or leaves sprayed with water droplets, etc. In addition, a large aperture should be used to compress the depth of field as much as possible, so the head is also very important.

Therefore, if you have a head with an aperture of 2.8 or above, it is not difficult to take such a photo in a specific scene.
