This method is effective because of how the human eye works. Our eyes are much more sensitive to changes in brightness than to subtle variations in color. By prioritizing luma data, engineers can drastically reduce file sizes—sometimes by up to 50%—without a perceived loss in quality for natural photographs. Real-World Applications Our eyes are much more sensitive to changes

Chroma subsampling is a technique that reduces the resolution of color information (chroma) while maintaining the full resolution of brightness information (luma). The 4:2:0 scheme is highly efficient because it records only a quarter of the original color data. This is achieved by sampling color for every 2x2 block of pixels rather than for every individual pixel. The Biological Basis

Today, 4:2:0 is the industry standard for consumer-grade digital media:
