Candid Low-Key 26th Birthday Portrait of Smiling Young Man with Lit Number Candles and Smartphone Screen

An Ultra HD, HDR, photorealistic vertical medium-shot indoor candid celebration portrait photograph strictly preserving the exact visual identity, facial geometry, body proportions, and warm, happy expression of the young man from the reference image, who serves as the primary visual identity reference. Maintain his authentic facial features: a structured oval-to-square face shape, defined cheek contours, clean masculine jawline, rounded chin, and natural fair-to-wheatish skin tone with realistic fine skin texture and visible natural pores illuminated by warm, flickering candlelight. He smiles warmly and affectionately with an authentic, joyful open-mouth smile revealing natural white teeth, looking downward toward the birthday candles in his hand. He features expressive dark almond-shaped brown eyes caught beneath naturally defined dark arched eyebrows, a straight prominent nose bridge with a small subtle mole on his left cheek, clean-shaven cheeks with a light shadow along his jawline, and soft, naturally contoured lips. His thick, dense dark brown-black hair is cut in a layered, textured crop with tousled, piecey strands and short bangs falling casually forward across his forehead and around his temples. Around his neck hangs a thin silver curb-chain necklace resting against his chest, and on his right wrist, he wears an elegant metallic silver chronograph wristwatch with a dark bezel and link bracelet. He has a lean, athletic build with well-proportioned shoulders and is dressed in a smart-casual dark evening outfit: a relaxed-fit, matte-black button-down cotton shirt worn casually unbuttoned deeply at the collar to reveal his upper chest and collarbone, with sleeves pulled down to the wrists. He poses in an intimate, candid celebratory posture: standing centered in a dimly lit space, cupping a miniature dark chocolate frosted birthday cupcake in his right hand in the lower-left foreground, topped with two gleaming silver metallic numeral candles shaped as "2" and "6" burning with bright, upright yellow-and-blue candle flames. In his raised left hand on the right side of the frame, he holds up a black-cased smartphone directly toward the lens; the brightly lit smartphone screen displays an incoming call interface reading "Birthday" above "26", with phone icons ("Remind Me", "Message", and a white glowing slider button reading "slide to answer") glowing over a warm amber abstract wallpaper. The setting is a minimalist, intimate indoor studio or celebration room: positioned directly in front of a neutral soft-grey or muted slate-blue fabric drape backdrop that falls smoothly into a creamy, cinematic out-of-focus background. Lighting is atmospheric, low-key cinematic illumination driven by two warm sources: the flickering, warm amber-and-blue glow from the two lit number candles illuminating his right hand, cupcake, and the lower right side of his smiling face, balanced by the soft, luminous display glow cast by the smartphone screen across his fingers, chest, and cheek, with deep, authentic dimensional soft shadows enveloping the surrounding space. Captured with an 85mm portrait prime lens simulation at f/2.2 from a vertical eye-level perspective matching the original reference orientation, tack-sharp optical focus on the burning silver number candles, cupcake, and smartphone screen in the foreground, with gentle, natural depth-of-field falloff softly softening his joyful face, authentic color reproduction, and high dynamic range photographic realism. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
