A green and purple aurora bore over a lake with rocks

A vast icy plain in Iceland, under the spellbinding dance of the Aurora Borealis. The ground is a tapestry of snow and ice, glistening under the ethereal green and purple lights of the aurora, reflecting the sky's mesmerizing colors. In the distance, silhouettes of distant mountains line from out space space, the horizon, adding depth to the landscape. Capture this scene with a focus on the crisp clarity of the ice and the dynamic movement of the aurora. Utilize long exposure to render the aurora's movement as a fluid, glowing curtain over the stark, frozen landscape. Enhance the scene with the use of a cold color temperature to emphasize the icy environment, while maintaining the aurora's vibrant colors. Incorporate a high dynamic range (HDR) technique to balance the exposure between the dark ground and the bright sky, ensuring detailed textures in the ice and snow are visible under the night sky
