How to adjust gopro wide-angle width

You can't adjust the wide-angle width of gopro. The wide angle is fixed and cannot be adjusted.

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens. Wide-angle lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses.

The focal length of a common wide-angle lens is generally 38-24 mm, and the viewing angle is 60-84 degrees. The ultra wide-angle lens has a focal length of 20- 13mm and a viewing angle of 94- 1 18 degrees. Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance.

Wide-angle digital camera has short focal length, wide viewing angle and deep scenery, which is suitable for taking photos of large scenes, such as architecture and scenery.

Precautions:

1, the scene shot by wide-angle lens is near big and far small, and the perspective effect is exaggerated. The closer the subject is to the camera, the more obvious the exaggeration becomes. Therefore, when taking portraits, people should not be too close to the camera, otherwise it is easy to take deformed photos of "fat nose and mouse ears". Of course, the works of art shot with this effect are excluded, such as The Hand Holding the Vote, which is a very famous photo.

When shooting a building with a wide-angle lens, the lens tilts up or down, which makes it easy for the parallel lines of the building edge contour to shrink or intersect in the distance. Pay attention to choose the contraction point on the center line of the framing picture, otherwise it will easily skew the building image and give people the illusion of collapse.

2. When a wide-angle lens uses a hood or a color filter, it is easy to block the periphery of the lens viewing angle and darken the image field. This situation is not easy to detect when shooting, but it is obvious in the photo. Therefore, when using accessories, be sure to understand their scope of use from the instructions. If there is no explanation in the manual, you should be more careful when shooting.

3. The flash coverage angle of electronic flash is generally equivalent to the viewing angle of 35mm lens of 135 camera. Therefore, when taking flash photography with a wide-angle lens smaller than 35mm, a diffuser should be added in front of the flash window of the flash. If not, you can wrap a layer of white paper or white handkerchief to increase the flash area.
