Coniferous forest silhouettes beneath starlit purple night sky.

Long exposure or high ISO night photography depicting evergreen forest treeline silhouetted against deep purple-tinted sky. Milky Way visible as luminous vertical band through upper atmosphere. Foreground trees backlit creating stark black profiles. Mist or fog occupies mid-ground valley between tree clusters. Color temperature shifts from cool cyan-teal in lower atmosphere to warm magenta-purple overhead. Astronomical observation conditions clearly evident with scattered stars, galactic core definition, and atmospheric light scattering creating gradient effect.
