What is the f in the lower left corner of the iPhone 15 camera? The "f" symbol in the lower left corner of the iPhone 15 mobile phone camera interface represents the aperture value, which is an important parameter in photography and is used to control the amount of light entering the lens and the depth of field effect.
1. Open the “Camera” app on your iPhone 15 phone.
2. Make sure the camera is in photo capture mode.
3. In the lower left corner of the viewfinder, you will see an "f" icon with a number next to it showing the current aperture value.
4. To adjust the aperture value, tap the "f" icon on the screen, then slide up or down to select a different aperture value.
- The smaller the aperture value (such as f/1.8), the larger the aperture and the more light that enters, which is suitable for shooting in dark light environments.
- The larger the aperture value (such as f/16), the smaller the aperture and the less light entering, which is suitable for shooting scenes such as landscapes that require a larger depth of field.
Please note that the camera software of the iPhone 15 does not support manual adjustment of the aperture value. The above operations are only used to display the current aperture value and its impact on the shooting effect. The Apple 15 mobile phone uses a fixed aperture design. In most cases, it will automatically adjust to the aperture setting that best suits the current environment.
