Is the effect of this photo taken with special effects or with special photographic equipment?

That circle can be the starry sky at night, or many small lights (in this case, it is necessary to have a short focal length and a long lens, and it is difficult to tell whether a light is a light or not). When shooting, the camera uses a slow gear and rotates the camera for exposure, so that you can shoot concentric circles of starlight or light. The length of this track has light with the exposure time. There is no requirement to use a camera. Do not be superstitious about SLR. Ordinary home card machines can also shoot, but the camera shooting speed is slow.

After shooting, cut the photo of this concentric circle in ps and add it to the landscape photo layer to get the photo with this effect.
