Samsung calls the camera on the new Galaxy S9 and Galaxy S9 Plus “the revolutionary camera that adapts like a human eye” because of a new feature called dual aperture.
Variable aperture simply means that the Samsung Galaxy S9 and S9 Plus can actually change the aperture of the lens. Aperture is a term that refers to how large the opening in the lens is a wide-open aperture will let in more light, while a narrower aperture will let in less light. In dark scenes, a wide aperture will create a brighter image.
The S9 offers two settings: an f/1.5 and an f/2.4, the f/1.5 being the brightest or widest of the two.
