Your camera will then automatically set an aperture that allows you to achieve that shutter speed. ISO in Photography: what it is and when to use your higher settings. No, shutter speed and ISO are not the same. Sometimes people get confused by this if they are shooting in their Aperture Priority mode.
So to compensate your camera adjusts the ISO, or sensitivity. Increasing the ISO when light levels are low helps you attain a faster shutter speed at which you can hold the camera. Your high ISO settings make your sensor more sensitive to light, allowing you to shoot in darker conditions. This comes at the expense of introducing noise to your images. However, modern cameras have improved their noise reduction significantly, and with most cameras you can shoot confidently at speeds up to ISO Roman Roeske says:.

Click to explore the relationship between the aperture and shutter speed. When you open a faucet all the way, water gushes out so you fill a bucket in a very short time. This is the same as pairing a large aperture and fast shutter speed to let in bright light for a short time. When you open a faucet just a little, water trickles out and so it takes a much longer time to fill a bucket. This is the same as pairing a small aperture and slow shutter speed to let in dim light for a longer time.
No matter which combination you choose, the bucket is filled the same amount. Likewise, an image in a camera can be exposed the same amount by various aperture and shutter speed combinations while also controlling motion and depth of field.
Shutter speed and aperture are inversely proportional to one another. This means that both shutter speed and aperture must be balanced in order to your images to have ideal exposure. As you increase your aperture, shutter speed must also be increased, in order to balance out the overall capture of your scene.
Both aperture and shutter speed impact the darkness or visibility of your footage or photos. Understanding the aperture and shutter speed of your shot is important as this helps you to take control over the exposure and adjust settings to ensure good or potentially perfect exposure.
