Ask the photographer for help! About shooting distance and plane position! Thank you very much

Distortion is easy to occur when the distance is too close, and the depth of field is limited. At least1.6m long shot, and strive for 2m long shot.

The height of the plane depends on the desired effect, and the height of the eyes is generally natural.

Your big head and small body may be caused by your wide-angle lens/short distance.
