Ultra-high-definition 4K photorealistic vertical portrait photo, captured at eye level with a full-frame camera: a smooth collie (short-haired collie), tricolor black-tan-white, sits on the bottom stair—the “naughty step”—with a guilty, hopeful expression, ears slightly back, head tilted, glossy nose and lifelike fur detail. A tiny, slightly askew Santa hat on its head; a strand of chewed tinsel and a torn ribbon near its paws. Background: cozy living room with a Christmas tree and warm fairy lights, stockings on the mantle, all softly out of focus with creamy bokeh. Lighting: soft natural window light from the left plus warm practicals from the tree; gentle shadows, crisp catchlights in the dog’s eyes. Camera/lens look: 85mm prime, f/1.8, 1/200s, ISO 400; shallow depth of field, rich depth, accurate color, lifelike textures. Composition: rule-of-thirds with the dog’s eyes on the upper third; wooden stair textures in foreground; warm festive color grade without oversaturation. Add a small, single-line caption at the bottom center in playful white hand-lettering with a subtle drop shadow: “Dear Santa, mis-chew-nderstood.” No other text.
