suppose the camera has only one len
.if i want to take a sharp image of a distant object,how should the len move,forward or backward.how about if nearby object?
To focus on a closer object, the lens must be move away from the focal plane.
that means move towards or backward the object?
To take a sharp image of a distant object with a camera that has only one lens, you would need to move the lens backward from its initial position. This helps focus the incoming light rays onto the camera's image sensor, resulting in a sharp image.
When you move the lens backward, it increases the distance between the lens and the image sensor. This allows the lens to adjust its focal length to bring the distant object into focus.
On the other hand, if you want to take a sharp image of a nearby object, you would need to move the lens forward from its initial position. This reduces the distance between the lens and the image sensor, allowing the lens to focus on the closer object.
In summary:
- Move the lens backward to focus on a distant object.
- Move the lens forward to focus on a nearby object.
