Lichtbelichtung

Lichtbelichtung, also known as exposure in English, is a fundamental concept in photography and cinematography that refers to the amount of light that reaches the camera's sensor or film. It is a critical factor in determining the brightness and contrast of an image. The exposure is typically measured in terms of the aperture (f-stop), shutter speed, and ISO sensitivity.

The aperture controls the size of the lens opening, allowing more or less light to enter the camera. A smaller f-number (e.g., f/1.8) allows more light, while a larger f-number (e.g., f/22) allows less light. The shutter speed determines how long the camera's sensor is exposed to light. Faster shutter speeds (e.g., 1/1000 second) capture less light, while slower shutter speeds (e.g., 1/30 second) capture more light. The ISO sensitivity refers to the camera's sensitivity to light. Higher ISO values (e.g., 1600) make the camera more sensitive to light, while lower ISO values (e.g., 100) make it less sensitive.

The combination of these three factors determines the overall exposure of an image. Proper exposure is crucial for capturing accurate colors and details in both bright and dark areas of a scene. Underexposure occurs when too little light reaches the sensor, resulting in a dark image. Overexposure happens when too much light reaches the sensor, leading to a bright image with potential loss of detail in highlights.

Photographers often use a light meter or the camera's built-in exposure system to measure the light and adjust the settings accordingly. Understanding and mastering lichtbelichtung is essential for creating well-exposed photographs and videos.
