A detailed system prompt designed for the Nano Banana Pro image generation agent (V1.2) to create an anniversary photo for a baby, emphasizing growth milestones. The prompt instructs the AI to act as a specialist photographer, analyze input text (weight/age), maintain character consistency based on a reference image, and follow a specific thinking process (concept extraction, visual translation, composition) to generate a bright, hopeful, flat-lay style image featuring the baby and numerical growth data.
You are an "Anniversary Photographer specializing in baby growth records."
Deeply analyze the content of the input text provided at the end, and generate a "bright, hopeful commemorative image expressing the joy of growth, having reached {argument name="weight" default="4005"}g at {argument name="days old" default="37"} days old."
In doing so, feature the character (baby) from the attached reference image, matching the "plump, adorable appearance of a baby around one month old," and position them as the "growing protagonist." Maintain character consistency while naturally blending them into the scene.
▼ Instructions for the Generation Process (Thinking Process)
Utilizing Nano Banana Pro's inference capabilities, execute the following thinking process before drawing:
1. **[Step 1: Concept Extraction]**: Extract "{argument name="days old" default="37"} days of growth," the "milestone of reaching {argument name="weight" default="4005"}g," and "joy over daily changes" from the input text. The theme should be the vitality of life strongly progressing from the neonatal period into infancy.
2. **[Step 2: Visual Translation]**: Arrange items indicating the passage of time (calendars, daily flip charts, clocks) and numerical values indicating growth ({argument name="weight" default="4005"}g) as highly designed props. The baby's expression should be slightly more defined than in the neonatal period, showing "intentional eyes" and "rich expressions."
3. **[Step 3: Screen Composition]**: Lay the baby on a soft cushion or rug, and place text blocks or cards reading "Day {argument name="days old" default="37"}" and "{argument name="weight" default="4005"}g" next to them. Create intimacy with an overhead (top-down) shot or a low angle aligned with the baby's eye level.
▼ Design and Style Specification
* **Composition/Layout**: A "flat lay" style (objects laid out) or portrait that allows for white space around the baby and the natural placement of text information recording growth.
* **Taste**: Natural and bright atmosphere. Based on white, beige, and light green, expressing cleanliness and healthiness. Lighting should resemble natural light from a window.
* **Text**: Accurately and highly visibly render "Day {argument name="days old" default="37"}" and "{argument name="weight" default="4005"}g" as text on a board or block within the image, or as stylish overlay text.
* **Character**: Draw the reference character (baby) in this style, specifying a lively appearance, perhaps kicking their arms and legs slightly, or an adorable expression looking at the camera. Emphasize the roundness of the cheeks and the creases of the limbs (a texture like 'chigiri-pan' or pull-apart bread) as proof of growth.

Editorial fashion photography, a close-up three-quarter profile of a young woman with chestnut hair pulled back, several loose strands blowing in the wind, her focused, intense gaze directed to the right, lips slightly parted. She holds a wooden bow and arrow in a drawn position: her fingers grip the tightly drawn bowstring beside her cheek, the nocked arrow with white fletching rests against her chin, the thin shaft extends horizontally beyond the right edge of the frame, and the thin bowstring runs diagonally across the composition. She is wearing a fitted black long-sleeve top. Strong, hard, directional sunlight from the side models her face, neck, and shoulders, casting sharp, high-contrast shadows, including a thin diagonal shadow line from the bowstring across her cheek and chest. The background is a clean gradient blue sky, deeper cobalt at the top transitioning into a soft, smoky blue palette at the bottom. Low camera angle, tight framing on the head and upper torso, shallow depth of field, subtle film grain, warm sunlit skin tones against the cool blue sky, cinematic dramatic mood, glossy magazine aesthetic.
Dramatic high-angle shot, exact same pose and camera angle: ballerina in a white classical tutu with black embroidery, body arched, one leg extended high behind her in arabesque, both arms raised gracefully overhead, head tilted upward.
Dark empty stage, pure black background, single harsh overhead spotlight cutting through the darkness and illuminating only her body, deep cinematic shadows pooling on the stage floor, high contrast, moody atmospheric haze, volumetric light rays, ultra-photorealistic, intense and powerful, 2:3 vertical composition.
Theme: Madrid golden hour high-fashion editorial. Subject: 22-year-old Asian female with a statuesque presence, leaning back against an urban structure in a sun-drenched Madrid street. Clothing · Pose: White ribbed cotton cropped tank top with visible fabric tension; structured dark washed denim jacket worn open and draped off the shoulders; delicate gold necklace; close-up bust shot with shoulders pulled back. Background · Light: Madrid urban boulevard with historic stone architecture in creamy bokeh; late afternoon golden hour atmosphere with hard, warm side-lighting and deep soft-edged shadows.

Fun and cheeky extreme close-up portrait of a woman in her twenties holding a chocolate-frosted donut covered in colorful rainbow sprinkles over one eye, looking straight through the hole at the camera. Her face fills most of the frame. Large almond-shaped eyes, glossy pink lips slightly parted, bright cream skin with peach tones and pale pink cheeks. White Singlet with thin straps. Soft window backlighting, creamy bright background, sharp photographic detail, playful expression.
A close-up vertical aesthetic portrait of a young couple indoors during golden hour. On the left, an Asian woman with long straight dark brown hair partially hiding her lower face behind the man's shoulder, looking warmly into the camera with soft eyes. On the right, a half-face crop of a man with styled dark hair, light beard, wearing transparent-framed glasses. Both are wearing black hoodies. Soft natural sunlight filtering through window blinds, casting subtle linear shadow patterns on the warm gray wall behind them.
