The photos taken by the original camera theoretically display leg thickness that is close to reality.
However, the actual shooting effect may still be affected by various factors, such as shooting angle, lighting conditions, camera focal length and angle of view, etc., which may to some extent affect the visual effect, making the legs appear thicker or thinner than they actually are.
Although the photos taken by the original camera should be closer to reality technically, relying solely on the photos to determine the thickness of the legs may not be entirely accurate. The most accurate way to evaluate is still to directly observe or use professional measurement tools.
