Achieving Even Lighting in Passport Photos

Even light exposure is defined as a uniform distribution of light across a photograph. This can also be referred to as "uniform" or "flat".

In photography, achieving uniform exposure can be a technical challenge. Overexposure occurs when there is too much light in the photo, while underexposure occurs when there is too little.

Rules for Even Exposure in Passport Photos

The government has established rules for the exposure of passport photos. These rules state that the photo must have uniform exposure.

The requirements for exposure are:

• The exposure must be uniform, with no under or overexposure.
• There should be no shadows on the face or background.
• There should be no reflection visible on the face or background.
