Earth Horizon from Low-Orbit Window View

A low orbital viewpoint frames the Earth horizon as the main subject, showing the planet curvature and a broad band of atmosphere glowing faintly with thin haze. The intent is quiet awe and scale, with city lights punctuating night side forms and a warm sunrise rim light defining edges. Window mullion or spacecraft frame appears at the lower edge as a subtle prop that anchors the viewer to a human vantage and suggests a square 1:1 crop centered on the horizon. Surfaces include glass with faint micro-reflections, the soft gaseous texture of the atmosphere, and the matte darkness of open space. The nearest details on the limb and city clusters resolve crisp and detailed, while the mid atmosphere softens into a gentle glow to create moderate layering. Light is warm on the sunrise rim and neutral-cool across the night side, with gentle separation of forms and a faint backlit halo around cloud tops. The composition reads tight to medium with a balanced square frame, eye-level viewpoint, and clean negative space above the horizon to emphasize curvature. A subtle sense of drift and slow rotation is implied by smeared distant star points and a slight motion blur on far city edges. The style is hyper-real photorealism with careful color grading to echo deep navy, warm gold, orange city tones, and cool haze blues from the palette.
