What's the relationship between aperture and shutter speed?


assistant
In photography, aperture represents the size of the opening in the lens, and shutter speed represents how long the shutter remains open to let in light to expose the image sensor. If you keep exposure constant, they have an inverse relationship. Opening the aperture wider results in shortening the shutter speed, and having a longer shutter speed means closing the aperture more.
