The setting on a DSLR that determines how much light the camera can absorb. Exposure Shutter Aperture ISO

The setting on a DSLR that determines how much light the camera can absorb is the aperture. The aperture is represented by f-stops and controls the size of the opening in the lens through which light passes. A larger aperture (e.g., f/2.8) allows more light to enter the camera, while a smaller aperture (e.g., f/16) allows less light to enter. This setting is crucial for controlling the exposure of the image, especially in low-light situations.
