Tips and Best Practices

• Optimal lighting setup: position the subject facing a window or use two soft lights at 45° angles to eliminate shadows and ensure even illumination, because uneven lighting or shadows on the face/background often lead to photo rejection.
• Neutral background choice: stand 1–5 m from a plain white or off-white wall with no textures or objects visible, because Congo passport rules require a clear, unobstructed background for accurate facial recognition.
• Correct camera height and distance: mount your camera or smartphone on a tripod at eye level about 5 m away, because shooting too close or at an angle causes perspective distortion and head-size errors.
• Proper framing and measurements: before cropping to the final 40×40 mm, ensure the head height measures 32–36 mm and eyes sit 20–30 mm from the bottom edge, because off-spec dimensions result in automatic disqualification.
• Expression and attire compliance: ask the subject for a neutral expression with mouth closed, remove eyeglasses and non-religious headwear, and tuck hair behind the ears, because any obstruction or exaggerated expression can trigger rejection.

Conclusion

Conclusion: With careful setup and attention to detail, you can capture a fully compliant 4×4 cm (40×40 mm) passport photo for Congo (Brazzaville) at home—saving time and avoiding costly rejections.
