An astronaut clad in a reflective spacesuit stands on the tranquil shore of a lake under a starlit sky. The scene is captured in stunning detail using the Fujifilm X-T3. Nearby, a large, luminous neon triangle casts a surreal glow, its vibrant colors dancing across the water's surface. The night is alive with the radiance of this geometric figure, enhanced by ray tracing techniques. The image is rendered in 8k UHD with HDR, capturing the sharp contrast between the soft glow of the neon and the deep shadows enveloping the surrounding landscape. The astronaut gazes at the neon shape, a reflection both in the water and within the mirrored visor of the helmet, creating an otherworldly fusion of technology and nature.
