Create a 4:5 vertical chef portrait in kitchen steam. A Chinese male chef stands in front of a steamer in a stainless-steel open kitchen, wearing an unbranded white chef jacket and dark gray apron. With both hands he lifts the lid of a large bamboo steamer, and dense white steam rises from the pot, partly obscuring the background. Three-quarter environmental portrait, subject centered slightly right, with blurred flame and metal countertop visible on the left, and no menu or signboard in the background. Lighting from cool-white overhead kitchen lights diffused by steam; palette of silver gray, white, warm firelight, and dark gray. Real restaurant back-kitchen photography, 35mm lens, realistic proportions and natural hand movement. No readable text, logo, watermark, brand, menu, restaurant name, or label anywhere.
