Use the environmental content and lighting described, ignoring publisher language such as free, HDRI, unclipped, resolution, or panoramic. Generate an independent ordinary rectilinear camera view of this kind of environment, NOT an HDRI, NOT 360 degrees or fisheye. Landscape 1536x1024 framing, realistic camera perspective, deep focus and natural materials. Keep the scene recognizable with plausible details specific to this environment. Include a modest clear foreground floor, ground or work surface for later controlled target placement, without letting an empty surface dominate the whole scene. Full realistic color, natural irregular arrangements and asymmetrical composition. No people, no text or logos, no watermark, no panels, no collage, no mirroring, no spherical projection or studio spheres, no extreme bokeh, no painted/CG appearance.

Landscape 1536x1024 framing, realistic camera perspective, deep focus and natural materials. Keep the scene recognizable with plausible details specific to this environment. Include a modest clear foreground floor, ground or work surface for later controlled target placement, without letting an empty surface dominate the whole scene. Full realistic color, natural irregular arrangements and asymmetrical composition. No people, no text or logos, no watermark, no panels, no collage, no mirroring, no spherical projection or studio spheres, no extreme bokeh, no painted/CG appearance.
