Regulating Brightness in Passport Photos: Ensuring Optimal Visibility

Brightness in photos refers to the overall lightness or darkness of an image, which is affected by the amount of light captured during shooting and the camera's settings.

Too much brightness can cause overexposure and too little can result in underexposure, both leading to loss of detail. In post-processing, brightness can be adjusted to enhance visibility and set the mood, but excessive adjustments can degrade image quality. Careful handling of brightness, along with contrast and saturation, can improve image compositions.

Rules for Brightness of Passport Photos

Brightness in passport photos must be balanced to ensure all facial features are clearly visible. The image should neither be overexposed (too bright) nor underexposed (too dark).

Generally, passport photos must have a even background, typically bg_color, and the lighting must be even to avoid shadows on the face or background. Directly lit from the front, the face should be clearly seen without harsh glares or reflections.
