Taking a Passport photo online at home requirements for the USA

[TrevorPlay]

If I decide to take a Passport photo online at home using my smartphone, what are the most critical requirements (beyond the white background) I must meet for the USA application?

The most critical requirements for your USA passport photo taken at home are maintaining a neutral expression with a closed mouth, ensuring the camera is at eye level to prevent distortion, and having perfectly even lighting that casts no shadows on your face or the white background.
