螢幕自帶光，棺材不用補光

A macro conceptual photograph in 16:9 wide composition: across the face of a bright screen made from a regular grid of glowing colored cubes, one small cube has gone dark, and that dead pixel lies inside a tiny open coffin. The coffin is a miniature matte casket, sized just to hold the cube, resting on the screen surface with its lid tipped open beside it and aligned with the grid. Inside, the dark cube rests on a small pale lining, its black faces sitting flush with the glowing field around it. From the surrounding grid cells, neighboring cubes lean in close, gathered at the coffin's head and sides like mourners, their colored glow washing across the casket as soft, even screen light. The regular grid of bright cubes continues on toward all four edges of the wide frame, fading into a gentle glow. Shot from a low, close angle just above the screen surface near the coffin's foot, the dark pixel and its open casket read at the center of the frame with clear margin on every side, while the gathered neighbors and the endless grid carry the story around it. Keep a shallow depth of field with soft bloom around each glowing cube, every surface smooth and blank.
