Indoor photography smoke

Are you referring to the smoke on the ground, like clouds, or the light beams seen in the sky?

The clouds and mist on the ground are created by the dry ice truck. Specifically, the dry ice truck heats the water to boiling, and then puts in the dry ice. The water vapor suddenly condenses into water droplets, which pass through the fan on the truck. Blow it out. Because it is heavier, it is closer to the ground.

The smoke in the air is produced by the cigarette machine heating a special smoke oil. Its function is to allow people to see the light beam and increase the performance effect. Professional e-liquid is harmless to the human body.
