Zooming in makes the camera’s field of view narrower, and in effect, it magnifies the center portion of the image. Zooming in using the optical zoom can improve angular resolution, but will never reveal a distant object that is obscured by another object.
Flat-Earthers claim that zooming in will fully reveal a ship that is partially obscured. In reality, the proportion of the ship which is hidden compared to that which is visible stays the same in the entire zoom range.

If a distant boat is not visible, then it is because of at least one of these reasons:
- Our eyes have limited angular resolution and are unable to resolve the ship at that distance.
- The atmospheric condition is limiting our visibility.
- The curvature of the Earth obscures the ship.
Flat-Earthers like to demonstrate that a previously invisible ship at a distance can be made visible by zooming in. They would use it to disprove Earth’s curvature. They are wrong. There are reasons other than Earth’s curvature that can obscure a distant boat.

Camera zoom works by enlarging the center portion of the image, or in other words, by making its field-of-view narrower. Zooming in on the setting sun will not reveal more of the sun, and will only enlarge the size of the sun in the resulting image.
Flat-Earthers are claiming that zooming in on a setting sun will reveal the entire sun, and somehow lift it out of the water. They are wrong. They simply used the incorrect exposure settings. In reality, zooming on the setting sun will never reveal the sun that is already obstructed by Earth’s curvature.

The amount of horizon curvature that appears in a photograph of the horizon depends on several factors:
- The altitude of the observer.
- The field of view of the camera.
- Lens distortions of the camera.
Some flat-Earthers assume that we should see the same amount of Earth’s curvature everywhere. And when they see the different amount of curvature in the different picture of Earth’s curvature, they wrongly took it as “proof” of some sort of misconduct.

Zooming in using a camera merely magnifies the center portion of the image. Changing zoom does not change an object’s position with respect to another object or the camera. It will not reveal more of a distant object.
Flat-Earthers often claim that zooming in will reveal distant objects that are ‘allegedly’ behind the curvature. They are wrong. If the object is really behind the curvature, then no amount of zooming can bring the object back into view.
