JPEG
JPEG is the most ubiquitous image quality criminal in the digital realm, performing alchemy called compression to shrink file sizes while erasing artists’ hard work without remorse. Its technique, built on the sacrifice of color depth and resolution, betrays photography enthusiasts and mocks the obsession with detail. Celebrated in the web world for its lightness, it reveals its true colors—an abysmal degradation—when printed or enlarged, silently confessing its own limitations. When it achieves its purpose, what remains is not satisfaction but a spectral afterimage of lost details.
