Photo style should match how the biodata will be used. A formal portrait usually works best, but a softer look can still be effective when done well.
Formal Is the Safer Default
A clear, well-lit, simple portrait usually works across communities and family preferences because it feels respectful and easy to share.
Casual Can Work if It Still Feels Polished
A relaxed photo is acceptable only when it still looks neat, high quality, and appropriate for a family-reviewed document.
