You can change the field of view (FOV) on your camera primarily by adjusting the working distance or changing the lens.
Here's a breakdown of the methods:
1. Adjusting the Working Distance
-
The easiest and often simplest approach is to change the working distance (WD). The WD refers to the distance from the lens to the object you are capturing.
-
Moving the lens farther away from the object increases the FOV. Conversely, moving the lens closer to the object decreases the FOV, magnifying the object within the captured image.
2. Changing the Lens
-
The second primary method is to swap your current lens for one with a different focal length.
-
Lenses with shorter focal lengths provide wider FOVs, capturing more of the scene. These are often referred to as "wide-angle lenses."
-
Lenses with longer focal lengths provide narrower FOVs, magnifying distant objects and reducing the amount of the scene captured. These are commonly known as "telephoto lenses."
Summary:
In short, you can change your camera's field of view by either physically moving the camera (and therefore changing the distance to the subject) or by swapping the lens for one with a different focal length.
