Capture standard (without SDK)
In this section, you will find how the capture standard for the user's selfie should be if you do not use our SDKs
For optimal performance of the IDCloud platform's capabilities, we recommend using our SDKs. They will ensure the best functioning of the product as a whole, both in terms of drop rate and in validating the Liveness.
To achieve better results in image capture, a capture standard has been defined. The image should be clear with sufficient frontal lighting. The face should be straight, facing the camera, free from objects or obstructions, and with a neutral expression.
Common issues in captured images include:
Lighting behind the client: Frontal lighting must be strong enough for a clear capture of the face.
Overexposed lighting: Frontal lighting needs to be adequate for a sharp capture.
Face too close to the camera: The face should be centered in the camera frame with proper lighting.
Blurry images: The person’s face needs to be well-focused at the moment of capture.
Shaky images: Stabilize the camera during capture.
Client wearing glasses: The client should not wear glasses or objects that obstruct full visibility of the face.
How to Obtain a Good Image Capture
For capturing and sending images, the ICAO standard is used. The ICAO (International Civil Aviation Organization) standard consists of characteristics that a photograph must comply with regarding capture and sending configurations:
Face Positioning and Additional Information:
The photo must be taken from the front—looking directly at the camera with the head upright. The face should be centered, and the shoulders must be aligned parallel to the camera's image plane.
The eyes should be naturally open—pupils and irises visible.
Glasses: The photo should be captured without glasses.
No hats, caps, or masks: The facial area must be clearly visible.
Neutral Expression: The face should maintain a neutral expression; the person should not smile, raise eyebrows, squint, or frown.
Hairstyle: Hair should not cover the eye visibility zone.
Lighting and Background:
The background should be light, smooth, and free of texture. It must not have stains, lines, or curves that are visible in the captured image. Light colors like light blue or white can be used, provided there is sufficient contrast between the face/hair area and the background.
The camera's color settings should not change based on the background color. There should be no shadows behind the face, and no visible objects in the background, such as people, furniture, patterned wallpaper, or plants.
The lighting must be adequate and uniform, evenly distributed across the face to avoid differences between the left and right sides. The photo should have brightness and good contrast between hair, face, and background. Poorly lit photos occur when lighting is only on the side, above, or below.
Images should be in JPEG, PNG, or JWT formats.
Captured images must be in color.
Sizes/Proportions
Selfies:
Recommended size: Aspect ratio 1920x1080 or 1080x1920;
Orientation: Portrait;
Size: Maximum 800kb, if necessary you can compress it to Jpeg92.
Documents:
Recommended size: HD aspect ratio - 1280x720 or 720x1280;
Minimum size: VGA aspect ratio - 640x480 or 480x640;
Orientation: There is no restriction regarding portrait or landscape orientation;
Size: Maximum 800kb, if necessary you can compress it to Jpeg92.
Examples of Standard and Non-Standard Photos:
The photo must include:
Color
Proper framing
Sharp and clear focus, free of ink marks or creases.
Look directly at the camera.
Show the natural skin tone.
Have appropriate brightness and contrast.
Neutral expression and eyes clearly visible.
No hair covering the eyes.
Facing the camera directly, without looking over the shoulder or tilted, and showing both edges of the face clearly.
With a simple light-colored background, preferably white.
With even lighting, no shadows or flash reflections on the face, and without red-eye.
No colored contact lenses.
No makeup.
The use of glasses is not recommended; however, if necessary:
The eyes must be clear, without reflections from flash or ambient light on the glasses, and without colored lenses.
The frame must not cover any part of the eyes.

Tips
Add instructions before capturing for the user:
Use capture "frames" to guide the client's positioning in front of the camera:
