photography style: shot with canon eos-1d x mark iii, 50mm lens, aperture f/4, golden ratio composition, side backlighting, cinematic lighting, crewdson-style foreground/midground/background layered exposure, overlay, 2.8/f, 5.6/f, 11.2/f stacking, layered and aperture dual-photo overlay, hard sci-fi realism. in the upper-middle part of the frame is a market in the sky: modern tech stalls emitting cold white and pale blue light, goods extending along an orbital ring like a ribbon of light; the orbital ring is a dark skeletal arc behind the market. above the market, a vast galactic nebula forms a glowing band. high above the market, chang'e flies, bearing the blue sky as she looks down, gazing down at the tech market from the void between the nebula and the street, watching this new world with joyful delight. she wears a flowing chinese robe, form-fitting and dignified, woven from moon-white and soft blue silk, embroidered with faint cloud and moon patterns, her long ribbons and sash drifting slightly in weightless space, a striking sight. below her, envoys of the world's major powers are browsing modern tech products. above chang'e, several flying objects sweep overhead — a spacecraft and a return capsule cutting diagonally across the sky at a clearly enlarged and prominent scale, their hulls and engine glow rendered with crisp detail, their long trails spanning the darkness and weaving beautiful cloud-like streaks across the sky, forming a majestic visual balance for the market below.
