Digital noise is apparent when a photo looks grainy.

Have you ever taken a picture at night with your cell phone or your pocket camera, and noticed that it looks really grainy? That is because the camera tried to compensate for the dark scene by choosing a high ISO, which causes more grain.

Understanding the Relationship between Aperture and Shutter Speed

Camera companies are constantly improving the ability of cameras to use high ISOs without as much grain. Since each camera is different, you would do well to do a few tests with your camera to see how high of an ISO you can shoot at without making the image overly grainy.

My guide informed us that the bighorn sheep in the park were dying off very quickly due to whooping cough, so I worked hard that week to capture pictures of the last few sheep in that area of the park.

Around 9AM on a cloudy day, I found a small group of bighorn sheep and started photographing them with a long mm lens.

The early hour and clouded sky made the situation quite dark for shooting.

This also impacted the depth-of field to blur out the rocks behind the bighorn sheep. Next, I set my shutter speed.

Whether you know it or not, you're always balancing camera or subject movement against depth of field because a change in one causes a change in the other.

As you've seen, shutter speeds and apertures each have a standard series of settings called "stops". With shutter speeds, each stop is a second or more, or a fraction of second indicating how long the shutter is open. The stops are arranged so that a change of 1 stop lets in half or twice the light of the next setting.

If you make the shutter speed 1 stop slower letting in 1 stop more lightand an aperture 1 full stop smaller letting in 1 stop less lightthe exposure doesn't change.

In all modes other than manual this happens automatically. However, you increase the depth of field slightly and also the possibility of blur from camera or subject movement. For fast-moving subjects you need a fast shutter speed although the focal length of the lens you are using, the closeness of the subject, and the direction in which it's moving also affect how motion is portrayed.

When photographing moving subjects shutter-priority mode is favored because it gives you direct control over the shutter speed. For maximum depth of field, with the entire scene sharp from near to far, you need a small aperture although the focal length of the lens and the distance to the subject also affects depth of field.
