Seaside Sunset Harbor Portrait

Subject: Skin Glow in the Evening Calm

Subject:
Vertical 9:16 photo-style portrait. An {argument name="person attributes" default="adult-looking woman"} stands slightly to the left of the center of the screen by the seaside near a harbor at twilight. The person is largely included from above the thighs to above the head, occupying about 70% of the lower part of the screen. In the upper half, leave a wide expanse of pale purple and pink sky, and softly blur the ships and sea in the background.

Character/Expression:
A natural and realistic adult woman. She has a somewhat Japanese-style well-proportioned face, and her long black hair is slightly ruffled by the sea breeze. Her gaze is towards the camera, her lips are lightly parted, and she has an expression with a calm lingering aftertaste. The evening light hits her face, neck, shoulders, and arms a little more strongly, making only her skin appear slightly brightly exposed.

Clothing/Pose:
{argument name="swimwear design" default="Pale lavender and orange small floral pattern bikini"}. The top has a ribbon tie at the chest, and the bottom has side ribbons, a design that balances cuteness and maturity. Raise the right arm above the head and touch the hair with the fingertips. The left arm is naturally lowered by the side of the body, and the waist is slightly twisted diagonally. The weight is shifted to one leg, creating a pose for a portrait that looks like it was naturally taken at the seaside.

Background/Light:
{argument name="location" default="Quiet harbor town seaside"}. In the background, several small fishing boats and excursion boats are lined up, and the sunset colors are reflected on the water surface. Small waves wash up on the sandy beach, and the distant harbor lights are softly blurred. The sky is a gradient of lavender, pink, and pale orange. Soft evening light enters from the upper left, creating slightly stronger highlights on the person's face and upper body, and thin purple shadows on the opposite side of the body.

Composition/Camera:
Medium telephoto lens portrait. The camera is slightly lower than chest height, at a slightly upward angle. Focus is on the person, and the background ships and waves are blurred with a shallow depth of field. Leave a wide empty space for the sky above the person's head, and include a little of the water's edge and sandy beach at the bottom. The harbor, sea, and sky are divided into foreground, middle ground, and background, and depth appears naturally.

Texture/Style:
Realistic photographic expression. Soft skin texture, highlights that are slightly blown out, and pale film-like tones. The contrast is low, with a transparent finish that utilizes the pink-purple evening landscape. Avoid excessive processing and make it a seaside portrait taken with natural light.

Negative:
Unnatural face, unnatural gaze, extra fingers, missing fingers, fusion of hands and feet, broken joints, poor contact between hair and hands, unnatural gravity, wrong perspective, shadows inconsistent with the light source, excessive blowout, plastic-like skin, garbled text, logos, watermarks.

主題：夕凪の肌光

主体：
縦長9:16の写真風ポートレート。夕暮れの港に近い海辺で、画面中央やや左に{argument name="人物属性" default="大人っぽい女性"}が立っている。人物は太もも上から頭上まで大きく入り、画面下部の約7割を占める。上半分には淡い紫とピンクの空を広く残し、背景の船と海はやわらかくぼかす。

人物・表情：
自然で現実感のある大人の女性。やや日系の整った顔立ちで、長い黒髪が海風で少し乱れている。目線はカメラへ向け、唇は軽く開き、落ち着いた余韻のある表情。顔、首、肩、腕に夕方の光が少し強めに当たり、肌だけがほんのり明るく露光して見える。

服装・ポーズ：
{argument name="水着のデザイン" default="淡いラベンダーとオレンジの小花柄ビキニ"}。胸元はリボン結び、ボトムはサイドリボン付きで、可愛さと大人っぽさが両立したデザイン。右腕を頭の上に上げ、指先で髪に触れる。左腕は体の横に自然に下ろし、腰は少し斜めにひねる。重心は片脚に寄せ、海辺で自然に撮られたようなポートレートのポーズ。

背景・光：
{argument name="場所" default="静かな港町の海辺"}。背後には小型の漁船や遊覧船が数隻並び、水面に夕焼け色が反射している。砂浜には小さな波が寄せ、遠くの港灯が柔らかくにじむ。空はラベンダー、ピンク、淡いオレンジのグラデーション。左上から夕方の柔らかい光が入り、人物の顔と上半身に少し強めのハイライト、体の反対側には薄い紫の影。

構図・カメラ：
中望遠レンズのポートレート。カメラは胸の高さより少し低め、わずかに見上げる角度。人物にピントを合わせ、背景の船と波は浅い被写界深度でぼかす。人物の頭上には広い空の余白を残し、下部には波打ち際と砂浜を少し入れる。港、海, 空が前景・中景・後景に分かれ、奥行きが自然に出ている。

質感・スタイル：
リアルな写真表現。やわらかい肌質、少し白飛び気味のハイライト、淡いフィルム調の色味。コントラストは低めで、ピンクパープルの夕景を活かした透明感のある仕上がり。過度な加工感は避け、自然光で撮った海辺のポートレートにする。
