1. Lens distortion: Camera lenses, especially wide-angle lenses, may have a certain degree of distortion, which is particularly pronounced in the edge areas and may cause facial features to be stretched or distorted, especially when shooting at close distances, making it easier to appear chubby, with a large nose or wide chin.
2. Perspective and Distance: The shooting angle and distance have a direct impact on the visual effect. For example, shooting from a low angle upwards will make the character look fatter, as such an angle will enhance the contours of the chin and nose. At the same time, if the shooting distance is too close, the lack of sufficient background to balance the image can cause the characters to appear disproportionate and appear even fatter.
3. Light and Shadow: The influence of light on photos is crucial. Inappropriate lighting conditions, such as direct strong light or side lighting, can create strong shadows and contrast between light and dark on the face, highlighting certain parts of the face while ignoring others, resulting in visual imbalance and a feeling of poor on camera effect. Lack of soft natural light or professional lighting can also make photos appear stiff and flat.
