Fresh Espresso with Crema and Backlit Steam

Use case: product-mockup
Asset type: square editorial food photograph for a cafe menu
Primary request: One freshly pulled cup of espresso with an intact tawny crema and a delicate plume of hot steam rising clearly above it.
Scene/backdrop: An unbranded ceramic espresso cup on a clean cafe window-side table at evening, with the cafe interior and window view melting into a soft blur.
Subject: The cup and its crema are the only hero; a plain empty saucer supports it with no extra clutter.
Style/medium: professional product photography, commercial studio lighting; photorealistic, high detail.
Composition/framing: square 1:1 composition, close eye-level three-quarter view; shallow depth of field with the front saucer rim and cup sharply resolved and the background smoothly dissolved into bokeh; sharp focus on the product, clean edges.
Lighting/mood: mixed warm practical interior light and soft window light for a cozy evening table; the window light comes from behind and slightly to the side so the steam is rim-lit and visible, while warm fill preserves the crema.
Materials/textures: accurate material rendering, realistic reflections; fine crema bubbles, glossy coffee surface, subtle ceramic glaze, believable translucent steam.
Constraints: coffee must look freshly brewed and hot; no people, no hands, no spoon or utensil inserted into the drink, no food props, no packaging, no text, no logo, no trademark, no watermark; natural brown crema, realistic cup shadow, no excessive HDR.
Avoid: flat front lighting that erases steam, broken crema, cold-looking coffee, clutter, distorted cup or saucer, fluorescent color, mismatched shadow.

황갈색 크레마가 온전히 남고 섬세한 김이 피어오르는 갓 추출한 에스프레소 한 잔. 저녁 카페 창가의 깨끗한 테이블 위 무상표 세라믹 잔과 빈 받침만 두고 배경은 부드러운 보케로 녹인다. 얕은 심도로 잔과 앞쪽 받침 테두리는 선명하게, 뒤는 흐리게 표현한다. 따뜻한 실내 조명과 부드러운 창광을 섞되 뒤측면 창광으로 김의 윤곽을 밝히고 따뜻한 보조광으로 크레마를 살린다. 전문 제품 사진, 상업용 스튜디오 조명, 제품에 선명한 초점과 깨끗한 가장자리, 정확한 재질과 사실적인 반사, 포토리얼리스틱, 고해상도 디테일. 사람과 손, 음료에 꽂힌 도구, 포장, 글자, 로고, 상표, 워터마크가 없다.
