ASCII半调旅行拼贴海报

Please create each travel photo I upload as a separate poster titled "ASCII HALFTONE TRAVEL COLLAGE" with high contrast. Do not combine multiple images into one; output each photo individually. The overall layout should be vertical, divided into an upper and lower section. The two sections should be close to a 1:1 ratio, separated by a clean, straight horizontal line. 【Upper Section | Original Photography】 Keep the original photo in the upper section. Preserve the identities of people, architectural structures, vehicles, natural landscapes, spatial relationships, camera angles, lighting directions, and color atmosphere exactly as they are. Do not redraw, replace, stretch, or distort any of these elements. Apply only light, professional photo grading to give the image the feel of an independent magazine, travel publication, or exhibition print. You may naturally extend the sky, roads, walls, or background environment to fit the format, but do not alter the main subjects. 【Lower Section | Halftone Character Collage】 Extract one most recognizable core subject from the photo, such as: A landmark building, architectural detail, archway, colonnade, vehicle, sculpture, person in a pose, street object, or natural landscape contour. Do not replicate the full original composition, and do not simply overlay an ASCII filter on the entire photo. Instead, recompose the subject by cropping, scaling, or changing local proportions. Rebuild the image using torn-paper photo fragments, black halftone dots, monospaced ASCII characters, registration marks, and paper texture. Let some areas of the subject retain a realistic photographic quality, while other areas gradually transition into a density map built from the following characters: . : / + = # @ The characters should follow the subject's volume, shading, contours, or direction of motion, so they actively construct the form rather than acting as meaningless background code. Add varied line weights of black halftone dots, photocopy grain, local ink loss, slight misregistration, torn paper fiber edges, and a few thin measurement lines. You may include one restrained calibration mark in red, but do not flood the image with red. Keep about 25% to 40% of the lower section as continuous off-white or warm gray paper negative space, so the photo fragments, character areas, and dots can breathe. 【Color Palette】 Extract colors from the original photo. Keep the colors most representative of the location or subject, but reduce overall saturation. Harmonize them with warm gray paper tones, black ink, and a small amount of calibration red. 【Typography】 Based on the location and subject of the photo, write: 1. A short, clear English title; 2. An archive code, such as "REC. 01 STUDY"; 3. A short English observation sentence. All text must be meaningful and legible. Do not generate gibberish or decorative fake text. The title should use a bold monospaced typewriter font. The archive code and observation sentence can be slightly smaller, but must remain readable. Place the text along the negative space, torn paper edges, halftone structure, or registration lines so it feels like part of the composition. 【Overall Mood】 The final result should feel like an independent publication, an experimental photobook, a photocopy archive, or a travel visual diary. The tone should be calm, rough, restrained, and intelligent, while still preserving the authentic atmosphere of the original travel moment. Avoid dark terminal-style backgrounds, computer code windows, cyberpunk neon effects, full-screen ASCII, random logos, unreadable glitch text, pure black backgrounds, generic template layouts, or cheap distortion effects.
