Deciding how much of the scene is in focus can make or break the impact of your shots, so here’s how to control it

The amount of a scene that’s sharp in front of and behind the focus point is known as depth of field. Depth of field is affected by three factors: the aperture, the focal length of the lens, and the distance between your camera and the subject. Once you have decided on a composition, the focal length and the distance will remain almost constant, so the main variable that you can control to alter the depth of field in your shot is the aperture. in a pleasing image. It’s always worth checking that you haven’t gone too far. The best way to take control of the depth of field is to set your camera to aperture-priority mode. You can then use the input dial to select the aperture you want, and the camera will automatically select the shutter speed for you.

You need to use large apertures, such as f/4 or f/2.8, to get images with very little in focus in front of and behind the focus point, and small apertures, such as f/11 or f/16, when you want to keep as much of the scene in focus as possible.
