Light and darkness are employed by the artist to create the illusion of deep space on a two-dimensional surface

Explanation:

Light is a tool widely used by artists to create spatial illusions. In this, it is fully combined with the dark interior space and isolated from the outside that prevents excess light. The dimensions of the work are diminished to control the effect of light and avoid unwanted reflections. The energetic contrast with the darkness of the environment is what captures the attention of those who observe this type of art.
