Aurora Borealis Northern Lights Sky

Aurora borealis northern lights over arctic landscape, dramatic green aurora curtains dancing across night sky with vertical columns and horizontal bands, aurora showing movement with swirls and waves, hints of purple and pink at upper edges of strongest aurora, stars visible in portions of sky not washed out by aurora brightness. Foreground landscape: snow-covered ground with small scattered evergreen trees silhouetted against glowing aurora sky, frozen lake surface partially visible reflecting aurora colors, distant mountain range silhouetted on horizon. Night sky illumination: aurora providing primary light source casting subtle green glow on snow-covered landscape, brightest aurora sections approaching white-green, dimmer sections showing true emerald green, natural color without over-saturation. Shot with 14mm ultra-wide lens at f/2.8 for low-light capabilities, long exposure (15-20 seconds) capturing aurora detail while maintaining some star points before trails, high ISO for sensitivity, positioned showing maximum sky coverage with landscape providing context and scale. Photorealistic aurora rendering: aurora showing authentic color gradients from bright white-green centers to emerald edges, vertical structure showing magnetic field lines, proper transparency allowing stars to show through dimmer sections, reflection in ice showing same colors with reduced intensity. Natural aurora color palette: predominantly emerald green with upper purple-magenta hints, white-green at brightest points, deep blue-black sky, snow-covered landscape showing subtle green aurora light cast, creating authentic northern lights experience meeting aurora photography standards.
