What are the creative photography techniques similar to light painting?

Generally, light painting should choose a very dark background, with small aperture, rough exposure and low sensitivity, and will not leave a moving figure.

The background of this work is bright, still in the water, so this background is superimposed in the later stage.

This kind of light painting is usually shot in a dark place, and the light pattern is usually produced by the light of a flashlight. Because the brightness of the light generated by the flashlight is much higher than the brightness of the surrounding light, the light emitted by the flashlight has a photosensitive effect on the camera photosensitive element in a very short time (the exposure time of the camera shutter), and because the surrounding light is very dark, the light shining on the human body is not enough to expose the camera photosensitive element, leaving only the halo generated by the flashlight in the final photo, leaving no figure. As for the background light of the sky, it is a little brighter than people's, so it will leave a slight scene. You can compare it, the sky is much darker than the light around the bike.
