ジオメトリック・コラージュ・ポスター

From the single photograph I upload, create one high-end art design poster in a vertical 3:4 format. Each photo produces its own separate piece; never collage several images together. Divide the frame horizontally into two zones of strictly equal height, 50% each, setting up a visual contrast between "real image × geometric artistic reconstruction".

Top zone — the real image
Work from the original photograph as the only source. Preserve as completely as possible the subject, the identifying features, the posture, the proportions, the clothing, the architectural structure, the animal's form, the relationships between objects and the character of the setting. Do not redesign the subject and do not casually add or remove important elements. Keep the quality of real photography, the natural light and the original colour mood, applying only restrained high-end grading so the image carries the feel of an art magazine, travel photography or an exhibition print. The edges of the scene may be extended naturally to suit the 3:4 composition, but stretching, distorting, replacing or reshaping the subject is forbidden.

Bottom zone — geometric visual echo
Take the most recognisable contours, posture, structure and visual hooks from the photograph above and redesign them as modernist geometric deconstruction plus paper-collage illustration. Do not reproduce the photograph realistically, and do not let it become ordinary cartoon or vector illustration. Instead, rebuild the subject from a small number of large, whole shapes — rectangles, circles, rounded squares, triangles, ellipses and irregular geometric blocks. Emphasise blockiness, modularity, overlapping shapes, the relationship between positive and negative form, and visual rhythm. Avoid chopping the subject into many small fragments of colour.

Delete the complicated background and keep only one to three key elements that help identify the original scene. Keep the subject at a moderate scale with a large amount of clean white space around it. It may sit off-centre according to the original's centre of gravity, be partly cropped, or be arranged out of alignment, so the lower zone reads as an independent art poster rather than a filter over the photograph.

Material and colour
Use flat fields of colour, paper collage, a light printmaking grain and a high-end print texture, with edges that carry a slight natural handmade quality. Avoid smooth vector, 3D, plastic texture and over-retouching. Extract two to four core colours from the original photograph and build a unified colour system from them, lifted and purified a little, favouring soft modern tones — cream white, warm beige, misty blue, grey-green, coral orange, warm brown, soft violet. Colour should be clear but never harsh; avoid dirty greys, dark browns, fluorescents and cheap candy colours.

Typography
Type is not the subject. By default add just one short English headline plus one group of very small supporting text. Do not repeat the headline and do not write long passages of copy. Set it in a refined magazine-style serif or a minimal sans serif, keeping it away from the subject and using the white space to position it.

The final result: real photography × geometric visual echo, large-plane deconstruction, restrained collage, soft high-end colour, paper grain, generous white space, modern editorial design and the quality of an art magazine cover. The two halves must clearly correspond, while telling the same picture in two completely different visual languages.
