Farbverzerrungen

Farbverzerrungen, also known as color distortion or color cast, refers to unwanted alterations in the colors of an image or video. This can manifest as a shift in hue, saturation, or brightness, making the colors appear unnatural or inaccurate compared to the original scene.

Several factors can contribute to color distortion. In photography and videography, improper white balance is a common culprit. White balance aims to ensure that white objects appear white under different lighting conditions, but an incorrect setting can cast an unnatural color tint (e.g., a blue or yellow cast) across the entire image. Lighting conditions themselves, such as incandescent bulbs emitting a warm, yellowish light or fluorescent lights producing a greenish hue, can also cause color shifts if not compensated for.

Furthermore, the limitations of display devices like monitors and televisions can introduce color distortion. Differences in calibration, panel technology, and viewing angles can lead to variations in how colors are perceived. In digital imaging, compression algorithms can sometimes subtly alter colors, especially in areas of fine detail or smooth gradients.

The correction of color distortions is often a crucial step in post-processing. This typically involves adjusting white balance, color temperature, and tint using specialized software. The goal is to restore the colors to their intended appearance, ensuring accurate and pleasing visual representation. Understanding the causes of color distortion is essential for both capturing and presenting images and videos faithfully.
