사진에서 예술적 포스터 만들기

Please create each uploaded photo as an independent, high-end design poster - no multi-image collages, each photo output separately. Overall use a 3:4 vertical composition, with the upper and lower areas at a 1:1 height ratio, each occupying 50% of the frame. The upper half retains the original photo, preserving the subject's identity, structure, pose, authentic texture, natural lighting, and original color atmosphere. Only apply subtle high-end color grading to give it an artistic, independent publication exhibition image quality. Add an appropriate frame, and the environmental background may be naturally extended, but do not stretch, distort, or alter the subject. The lower half first understands the core subject, subject relationships, structural flow, emotion, and visual metaphors most worth remembering from the original photo, then reconstructs an abstract expressionist hand-painted oil painting material collage. Do not copy the photo object by object, and do not fill the entire frame. Instead, remove irrelevant details and retain only the structures, flows, and visual memory points that best represent the original subject. Transform and re-express it cleverly through hand-painted oil paint, material collage, colored crayon texture, and a small amount of paper fragment reassembly, so that viewers can immediately recognize its correspondence with the original photo. The subject is presented as a small-scale stamp form, not requiring complete replication, but identified through only a few most critical contours, postures, directions, and relationships. The subject's lines use clearly chalk / crayon hand-painted oil painting strokes: thickness varies slightly, with dry granular texture, intermittent powder fall-off, subtle trembling, and edges that do not fully close, like casual lines drawn directly on rough paper. Slight tilting, repetition, hesitation, and clumsiness are acceptable, but it must not become a sloppy sketch. Local areas may use short strokes, cross-hatching, simple grids, and light smudging to express structure, without realistic volumetric modeling. The overall material collage logic is retained. The subject and a few auxiliary elements may be composed of paper fragments, collage shapes, pastel color blocks, and hand-drawn brushstrokes, preserving subtle cut edges, layering relationships, and handmade feel - but these only serve summarization and reconstruction, not trivial decoration. The surrounding area may include an extremely small number of star points, flower branches, ripples, geometric symbols, or everyday small elements related to the original photo's mood, as echoes, without forming secondary visual focal points. The composition maintains the relationship between a small stamp-sized subject and large areas of negative space. Position it freely according to the subject's own direction, proportion, and visual weight - it may be off-center, edge-hugging, suspended, or partially cropped. The negative space must be a deliberate compositional language, not merely empty background. Together with the subject, collage elements, text, and a few brushstrokes, it forms positive-negative relationships, density variation, gathering and dispersal, and symmetrical balance, creating clear breathing room, spatial depth, and pauses. Trimming is acceptable, but do not fill the frame - let the subject appear as a visual stamp carefully placed on a large sheet of paper. The background must form a clear yet gentle contrast with the subject - hue, brightness, and texture must not all blur together. The background paper may use warm brown kraft paper, recycled paper, light handmade paper, or other paper bases matching the original photo's character, but it must be separated from the subject in line density, color block brightness, or hue so the subject emerges clearly. The background retains authentic paper grain and granular texture, clean and natural, without dirty smudging. Extract 2 - 4 colors from the original photo that are most prevalent, most recognizable, and most representative of the image's spirit, and rebalance them into a harmonious, clear pastel palette. Natural results may include creamy yellow-pink, honey peach orange, light sky blue, mint green, tangerine yellow, light purple, and other bright colors, brightened with white or cream-yellow lines. The overall feel should be bright, warm, healing, and full of life, while maintaining sufficient distinction from the background - avoid gray, dirty brown, dull Morandi tones, fluorescent colors, and cheap candy-like sweetness. Text is used only for minimal functional intervention, with no language restriction. Freely distill a small number of short phrases or text fragments from the photo's subject, emotion, action, memory, or metaphor. Use light-weight, spacious typography with slight irregular letter-spacing or a stamp-like misprint feel, contrasting with the loose hand-drawn lines. The text sits quietly within the negative space, close to the subject or arranged along the image's direction, forming a natural image-text mixed layout with the illustration - not a fixed title template. The overall result presents a high-end visual effect composed of paper texture, pastel crayon oil painting, a small amount of material collage, a small stamp-sized subject, large areas of meaningful negative space, and loose image-text mixed layout. The key is not to copy the photo, but to understand the original image's visual language and re-express the original subject in a more clever, brighter, and more breathable way. Avoid object-by-object replication, background and subject blurring together, a filled frame, realistic rendering, detailed outlining, excessive gloss, over-decoration, children's template feel, 3D feel, and commercial poster feel.
