真实照片与像素色彩索引对比海报
Use a single real photo as the sole source of content to create a vertical top-and-bottom comparison editorial poster. The upper half completely preserves the real photographic texture, subject identity, quantity, pose, spatial relationship, lighting, and composition of the input photo, without turning the photo into an illustration; the lower half is a stylized re-rendering area of the same photo: on warm white paper, the image is refined into four equal-sized square pixel color block indices, respectively corresponding to the most recognizable subject outline, architectural or object structure, relationship between main colors and light/shadow, and one environmental detail from the photo. Each grid uses hard-edged pixel blocks with a limited number of colors and a low-resolution grid feel, preserving traceable forms instead of random mosaics. The four grids are arranged in a 2×2 layout with ample paper space left around them; use thin black crosshair crop/registration marks to frame the index area, adding a very small amount of small bilingual titles and fields, such as "COLOR INDEX / SCENE STUDY," with restrained and clear text like print proof annotations that do not overshadow the main content. The lower half must look like a designed color index card, rather than a filter, ordinary pixelation, or repeated photo; do not add irrelevant objects or change the theme of the photo. The upper and lower areas each occupy about half, with a clear horizontal boundary; side-by-side layout is prohibited, multi-image collages are prohibited, "original/AI image" corner marks are prohibited, and watermarks and brand logos are prohibited. All colors are extracted and compressed from the input photo, and the content of the four grids changes according to the subject of the photo, applicable to any photo such as people, animals, architecture, street scenes, nature, interiors, food, and objects.
About this prompt
The poster delivers a striking side‑by‑side contrast: the upper half shows the unaltered, richly textured photo, and the lower half presents a stylized color‑index rendering of that same image. Four equally sized pixel‑block grids sit beneath the photo, each capturing a different element—subject outline, structure, light‑shadow hierarchy, and an environmental detail—giving it a deliberately low‑resolution, blocky look that feels like a teaching card. The effect hinges on two directives: keep the top half “real photographic texture” and render the bottom half with “hard‑edged pixel blocks” on warm white paper. The layout uses a 2×2 grid with a clear horizontal divider, thin black crosshair crop marks, and minimal bilingual captioning, so the viewer can focus on the transformation rather than graphic embellishment. The color scheme is strictly derived from the original image, ensuring the index feels authentic to the source. To reuse, supply any photo file as input; the prompt will automatically generate the two halves. If you prefer a black‑and‑white design, simply instruct the pixel grid to use a grayscale palette. For a more playful layout, swap the bottom grid arrangement or add a subtle drop shadow to the index cards while keeping the overall split rule.
