Chroma Noise Chroma noise, also known as color noise, is a type of digital image noise characterized by random variations in color or hue, typically seen as speckles or splotches in areas of uniform color in an image. Chroma noise is caused by various factors during image capture and processing, including sensor limitations, high ISO settings, and compression algorithms.
It is most noticeable in areas of shadow or low-light, where the signal-to-noise ratio is low. Chroma noise can degrade image quality and reduce color fidelity, leading to a loss of detail and overall clarity. To reduce chroma noise, photographers can use lower ISO settings, employ noise reduction algorithms during post-processing, or utilize noise reduction features available in camera settings or software. |
