How to control the depth of field in landscape photography.

There are three factors that affect the depth of field: aperture, focal length and distance. In landscape photography, the choice of focusing distance is a magic weapon to control the depth of field.

So how to control the depth of field in landscape photography?

First, focus on the position of 1/4 or 1/3 at the bottom of the screen, and then play back the enlarged photo after shooting to see if the nearest scene and the farthest scene in the photo are clear:

If the near is clear and the far is not clear, it means that the focusing distance is a little close. Select a place slightly away from the current focus distance to focus, and re-shoot and view the photos.

If the distance is clear and the distance is unclear, it means that the focus distance is a bit far. Choose a place closer to the current focus distance to focus, take a new photo and view the photo.

If you can't see the distance clearly when adjusting, and you can't always find the right distance, then you can reduce the aperture by one level at this time.

This method is different from the "down 1/3 focusing method" widely circulated on the Internet and introduced in other books. The principle of this method is very simple, that is, by moving closer to the focus position, the close shot is just outside the "depth of field near the boundary", so that the recent scene will be clear. If the distance is not clear at this time, narrow the aperture to solve it.

It doesn't matter if you don't understand some principles. If you shoot more, you will have your own experience and you will be able to grasp the focus position more accurately.
