When taking photos with smartphones, many people may encounter the problem of standing in the middle of the camera with a rear camera, but the face is crooked and the mouth is slanted, which is quite troublesome. This is not a problem with the quality of the camera, but involves many factors such as camera angle, light, lens distortion and so on.
1. Tilt caused by the angle of the photo:
Visual errors: When taking photos with the rear camera, they tend to be affected by visual errors. Even if you shoot from a central position, your face may be mistaken for a crooked face due to the angle of view. This is a common perceptual error with the human eye.
Shooting height: The height of the camera is closely related to the height of the subject. If the camera height is low, the upper body of the subject tends to appear larger, while the lower body appears smaller, resulting in a visual skew.
Shooting angle: The camera angle can also affect the visual effect of the picture. If the shooting angle is skewed, the face is likely to be crooked even if you are standing in the middle.
2. Deviation caused by light factor:
Light and shadow effects: The angle and intensity of the light have a significant impact on the outcome of the shot. In some special light conditions, such as strong backlighting or side lighting, it may cause excessive shadows on the face and produce a visual skew.
Reflection Problem: Reflection is when light is reflected by an object, forming a brighter spot. If light is reflected on one side of the face, it will make that side of the face particularly bright and the other side appear relatively dark, creating the illusion of a crooked face.
3. Tilt caused by lens distortion:
Lens distortion: The rear camera's lens suffers from some distortion, especially when shooting at wide angles. Lens distortion can cause the ratio of the center and edges of the frame to change, making the face look crooked.
Camera quality: Some mobile phone cameras may have issues with uneven quality or long lifespans, which can also cause lens distortion and skew the results.
How to deal with it: Adjust the shooting angle: When shooting, pay attention to adjusting the angle of the camera so that it is parallel to the subject. Stand in the middle and try to avoid tilting the camera.
Use light wisely: Shoot in a well-lit environment and try to avoid strong backlights or side lights. If needed, you can adjust the shooting angle to avoid direct light.
Avoid special environments: In special environments, such as places with strong reflections, you can choose to adjust the shooting position to avoid direct reflection of light on your face.
Use beautifying: Some mobile camera apps offer beautification features that allow you to adjust the effects through software, including face slimming, straightening, and more, to compensate for the skew caused by the shooting angle.
Choose a better camera: When buying a phone, choose one with a better camera quality to reduce skew caused by lens quality issues.
Conclusion: The phenomenon of the rear camera shooting a crooked face and a slanted mouth mainly involves many factors such as shooting angle, light, and lens distortion. In practice, users can effectively reduce the sense of skew by adjusting the shooting angle, paying attention to the lighting conditions, and using the beautification function.
In addition, choosing a mobile phone with a good camera quality is also an important factor in improving the photo effect. By combining these methods, users can better cope with the skew that can occur in rear camera shots, and achieve more satisfactory results.
