In stagecraft, what is commonly used to create atmospheric effects like fog or rain?

In stagecraft, atmospheric effects such as fog or rain are effectively created using special effects techniques. These techniques encompass a range of methods and equipment tailored specifically for generating illusions and enhancing the visual experience of a performance. For fog, specialized machines like fog or smoke machines are employed to disperse a vapor that mimics the look of fog in a scene. Rain effects can be produced using water systems or simulated with sound and lighting to create the illusion of rain falling.

Other tools, such as lighting fixtures, primarily focus on visibility and mood rather than creating atmospheric effects. Sound boards are used to control audio elements, which can enhance the overall atmosphere but do not directly create visual effects. Costume designs are integral to character representation but do not contribute to generating atmospheric elements. Hence, special effects techniques stand out as the dedicated approach for crafting these enchanting visuals on stage.
