Double exposure, a technique that combines two photos to create a single image, has been masterfully used by talented artists to create a striking visual. The resulting image takes on a blend of the two images to create a unique effect. In this case, the artists have used cogwheels in the brain to create the illusion of a complicated, interconnected thinking process. The double exposure technique is prevalent in AI art, as it evokes concepts of artificial intelligence and computer processing. This particular piece showcases the incredible talent and versatility of the artists, who have used believe it or not, smoke and fluid dynamics to create an ethereal background that optical illusions and brain-mediated visual effects create an immersive experience.
