盛夏海边浅滩双人手机超广角自拍

Direction: 2 fictional adult Japanese women over 21 years old, at the moment of entering the shallow water area of a summer beach, a vertical selfie casually taken by the woman on the left using a smartphone's 0.5x ultra-wide-angle camera. Not beautifying the characters into portraits, but conveying the shooting reason of 'entering the sea with a friend, playing around and stretching out an arm to take a shot, which accidentally left a very summery photo,' a daily SNS snapshot. Avoid perfected poses or advertisement-like staging, emphasize the closeness of the shooting distance, the enlarged foreground arm, hair messed up by the sea breeze, moments where faces cannot be seen clearly, with the backlit sparkling water surface as the protagonist. 
Mood: The openness of a midsummer noon, casual and relaxed between friends, slightly random and accidental mobile phone photo. Not the glamour of a travel brochure, but an ordinary summer vacation record kept in a personal phone album. Neither poses with a perfect smile for the camera, prioritizing capturing the atmosphere of the moment. 
Model Left: Fictional adult Japanese woman over 21 years old. Healthy and naturally curved figure. There is a full natural volume at the chest area through the clothes, but no single part of the body is taken as the protagonist of the photo. Naturally presented as a friend entering the sea. 
Model Right: Fictional adult Japanese woman over 21 years old. Friend of the woman on the left. Healthy adult female physique, same height, body type, and pose as the woman on the left are avoided to give natural individual differences. Does not imitate real people, celebrities, or influencers. 
Face: Neither shows the face clearly. The woman on the left tilts her head to the right, with one hand and the black hair blown by the sea breeze overlapping part of the cheek to the eyes, making the expression almost unrecognizable. The woman on the right is in a back-to-oblique-back view facing the sea side, with her face almost invisible. Not a front-facing portrait for facial recognition, but an amount of information that stands as an accidental selfie between friends. 
Hair: Both have black long hair. Not perfect straight hair like a beauty advertisement; the sea breeze separates the hair strands, with a few fine hairs scattering horizontally, strands falling over the face, and uneven hair ends. The backlit part has only subtle rim light, and the black hair on the shadow side is slightly crushed due to smartphone exposure. 
Body: Realistic bone structure and center of gravity of adult women. Standing asymmetrically, with weight slightly shifted to one leg on the unstable sand of the shallows. The woman on the left twists her upper body slightly to take the selfie, while the woman on the right moves forward toward the deeper part of the sea, stepping forward with one leg. Body proportions are not exaggerated, only the perspective of the ultra-wide angle is boldly preserved. 
Skin: Natural skin exposed to strong summer sunlight. Preserves subtle skin texture, slight color variations, gloss on arms or shoulders, and fine moisture brought by seawater. No uniform smoothness like a beauty filter; highlights in the backlit parts are slightly overexposed, and shadow sides lack gradation like a smartphone. 
Outfit Left: Dark blue form-fitting short-sleeved ribbed top. Lower body is extremely low-waist casual pants, waistline low near the hip bone, but naturally fixed as clothing, ensuring necessary coverage. Does not reveal underwear or skin in an unnatural way, nor adopts a coordinate-style symmetrical wear, adding natural folds and drapes to the extent of being slightly shifted during play by the sea. 
Outfit Right: White-colored loose short-sleeved T-shirt and light blue low-waist denim shorts. The waist position is slightly higher than the woman on the left so that the two do not appear to have the same clothing structure. One arm casually holds a thin black coat or lightweight bag brought to the beach. 
Accessories: Visible accessories are minimized. No large jewelry used while playing by the sea. The smartphone body used by the woman on the left for shooting is close to the outside of the frame; if necessary, only a small part of the case edge or the holding part should be naturally revealed. 
Scene Objects: A thin black coat or lightweight bag casually held by one arm of the woman on the right. The sea surface has small ripples and slender white reflections. Avoid artificial props, reflectors, lighting equipment, or decorations for resort advertisements. 
Pose Left: From the bottom left to near the center of the screen. The body still faces the sea side, only the upper body is slightly turned toward the camera. One arm is greatly extended holding the smartphone for a selfie, thus the forearm appears huge with extreme perspective from the bottom center toward the left shoulder. The other hand is lightly raised to the face, blocking part of the face along with the hair blown by the sea breeze. No smile, presenting a subtle expression as if in the middle of shooting. 
Pose Right: Center to the right side of the screen. Oblique back view facing the bay side. Left leg steps slightly forward walking in the shallows, one arm extends high diagonally upward toward the horizon, with the index and middle fingers naturally making a V-sign. The wrist is slightly tilted back, not making a perfectly symmetrical pose. 
Water: Shallow and highly transparent seawater. Water depth is about 10-30cm depending on the position, with both immersed to near the ankles or calves. Yellow-brown sand ripples show through the bottom; the color of the sea is not a single vivid turquoise, but a mixture of grayish-blue, slight green, warm colors of the seabed, and white reflections of the sun. Small waves overlap multiple times almost parallel to the horizon. 
Lighting: High sun from mid-morning to early afternoon. The sun is located from the front right to nearly the front of the screen, with the characters partially backlit. Small ripples on the water surface produce many white specular highlights, some of which are blown out like a smartphone. Hair shadows are slightly crushed, and bright spots on the skin are strongly irradiated. Do not use HDR to completely equalize the characters and the sea, preserving the exposure difference of natural light. 
Effect: Sea breeze makes the hair flutter, shallow water sways slightly around the legs. Arms or hair can have small movements at the edge from hand tremors. Water surface highlights have slight clipping characteristic of smartphones, and there is slight stretching and lens distortion like an ultra-wide angle around the periphery of the screen. Not cinematic color grading, but color processing close to a standard smartphone camera. 
Camera: Assuming an ultra-wide-angle shot equivalent to 0.5x of a recent smartphone's rear or front camera, field of view 13-16mm equivalent. 9:16 vertical position. The woman on the left fully extends her arm, holding the phone at a position slightly higher than her head, tilting slightly downward toward the two. Due to the close distance of the subject, the foreground arm is extremely enlarged, and the distance between the characters and the sea feels wider than reality. Portrait mode is not used; a smartphone-style depiction with a relatively wide focus from the background to the characters. Exposure is slightly affected by the strong reflection of the water surface, making character shadows slightly dark. 
Imperfections: Shot with one hand extending the phone, so the horizon is slightly tilted by a few degrees, and the center composition is also slightly offset. There is subtle motion blur in the hair part, light noise in dark areas, and slight highlight blowouts on the water surface. Clothes have small folds from the sea breeze and body movements. Shoulder heights, leg angles, hair volume, and clothing positions are not perfectly unified. There is an extremely light texture like JPEG preservation or SNS compression, but no intentional low-quality processing is done. 
Background: Top part of the screen about 40% is the summer sky. Not just blue sky; there is a slightly dark large cumulus cloud above the center, mixed with bright white clouds and blue sky around it. The horizon is placed above the center of the screen, and more than the bottom half is occupied by the shallow sea surface. No large resort facilities or gaudy tropical signs are placed in the distance, establishing it as an ordinary beach. 
Atmosphere: Midsummer air where strong sunlight, moist sea breeze, and the smell of the tide can be imagined. Not a model shoot, but a sudden moment when two friends raise their phones while entering the shallows. Even if the water surface is too bright, the face is covered by hair, or the arm is hugely distorted, there is no reshoot, posting this imperfection as-is to SNS. 
Composition: 9:16 portrait. The horizon is near the top 35-40%. The forearm of the woman on the left appearing huge enters from the bottom center diagonally to the upper left, followed by the left shoulder and head. The woman on the right is in the middle-right, slightly further than the left. The V-sign held high by the woman on the right extends toward the sky and horizon. The faces of the characters are not placed in the center; the screen is composed of the sea, the arm, and the actions of the two. Do not correct the unruly perspective characteristic of ultra-wide angles. 
Photo Quality: Not high-end camera work, but the level of a direct SNS post from a recent smartphone. No background blur, no overly shallow depth of field. Sea, clouds, characters, and distance retain information within the necessary range, coexisting with slight smartphone HDR, highlight blowouts, dark noise, ultra-wide-angle distortion, and a slight sense of compression. 
Negative: Imitation of real people or celebrities' faces, characters who look underage, excessive skin retouching, doll-like faces, plastic-like skin, unrealistic bone structure, extremely exaggerated body proportions, composition with specific body parts as protagonists, perfect posing like advertisement shoots, studio lighting, excessive background blur, excessive HDR, overly vivid turquoise sea like tropical resort advertisements, perfectly tidy hair, symmetrical arrangement of characters, composition shot from a distance by a third party, UI, back icon, search icon, SNS buttons, screenshot frame, text, existing logos, existing watermarks. 
Watermark Direction: Integrate the string '@Live_life_style' as a very low-key signature that exists accidentally in the beach environment from the time of shooting, rather than a logo pasted on later. 
Integration Method: Slender sun reflections and small ripples formed on the shallow water at the bottom of the screen naturally form a shape that can be read as '@Live_life_style' upon close inspection. Not ordinary printed characters or digital subtitles, but a combination of the brightness and darkness of the water surface, fine white reflections, and sand ripples on the seabed forming a character-like shape. 
Subtle Visibility: The watermark is not noticed when first looking at the photo, and only readable upon searching for it. Do not use pure white text brighter than the sea surface, but a contrast equivalent to the surrounding reflections. 
Placement: Toward the bottom right of the screen, but not close to the edge, and not overlaid on the characters' bodies. Placed on the shallow water part sufficiently far from the legs of the woman on the right, not imitating the position of an SNS UI. 
Material Behavior: The character shapes are not complete font outlines; wave fluctuations make line widths slightly uneven, with some parts interrupted or distorted. Appearing through the perspective of seabed sand ripples and water surface reflections. 
Lighting Interaction: Becomes bright as a water surface reflection consistent with the sun's backlight direction, slightly breaking up in the same direction as the surrounding small waves. Do not make flattened text that deviates from shadows or highlights. 
Avoid: Post-pasted white text, thick logos, black outlines, drop shadows, stickers, SNS UI-style display, text directly on the characters' bodies, abnormally legible typography, lighting unrelated to the surroundings.
