自然风光：冰岛间歇泉

Medium wide shot at eye level of a powerful Icelandic geyser erupting, a tall column of hot water and steam blasting high into the air, catching the light as it arcs and falls back into the pool. The foreground shows a shallow, brilliantly blue-tinged geothermal pool ringed by pale cream and soft-blue mineral sinter terraces with intricate, rippled formations; warm steam drifts across the water surface in slow-moving clouds. Beyond the pool, the flat geothermal field stretches toward distant grey mountains under a soft, overcast sky with diffuse light. A few small distant silhouettes of visitors stand safely back from the eruption, giving scale. The air shimmers with heat haze around the vent. Lighting: soft, diffuse overcast light, even and gentle, making the blue water glow. Color palette: pale blue, cream white, soft grey, with touches of ochre mineral staining.
