The operation of shining light for a certain period of time on the photosensitive surface of the image sensor of a digital camera, photographic film, photographic paper, etc. When the photosensitive layer is irradiated with light, it is called exposure, but there is no strict distinction between the two and they are often used interchangeably. Exposure is achieved by using the camera shutter, lens cap, or by turning on and off the lighting. The state of exposure can be called overexposure, correct exposure, or underexposure.

デジタルカメラの撮像素子や,写真フィルム,印画紙などの感光面に,一定時間の光を照射する操作。感光層が光で照射される場合を露光と呼ぶが,両者は厳密には区別されず,同一に使われることが多い。露出はカメラのシャッター,レンズキャップあるいは照明光の点滅などで行なわれる。露出の状態について,露出過度(露出オーバー),適正露出,露出不足(露出アンダー)の呼び方がある。
