1. Low shooting angle
In general, the lens needs to be above eye level for a person to look beautiful in a picture. Here is a good illustration:
If it’s a selfie, hold the camera a bit higher, ask the photographer to lift it, ask a buddy who is taller to snap the photo, or slightly crouch down. Additionally, slightly (but not too significantly) lower your chin; nobody wants to see what’s in your nose.
2. Incorrect focal length
Depending on the focal length of the lens, faces seem different (18mm, 35mm, 200mm, etc.).
An excellent focal length range for photos that look natural is between 35mm and 85mm. However, each person has a unique face. As a result, occasionally people think they look fantastic in the mirror but frightening in pictures.
Ask a friend to bring a zoom camera and snap a few images with you, filling the frame with a face each time, to determine your ideal focal length. Then you review them and decide which you like best.
Try a focal length between medium and long. Ask the photographer to either step back and zoom in or zoom in and out to achieve the perfect shot.
