enhance the attached image to true 4k resolution increasing clarity sharpness and detail without altering the visual content all elements architecture landscape textures shadows colors and people must remain exactly the same in design and geometry the goal is not to change the image but to make every existing detail more crisp defined and photorealistic upscaling requirements upscale to 3840 2160 4k resolution preserve the original color palette tone shadows gradients and highlights do not modify the composition proportions perspective or structure do not remove or add objects unless necessary to correct upscaling artifacts keep all lighting direction and intensity identical do not artificially brighten or stylize this is a purity enhancement pass only quality enhancement instructions apply even enhancement across the entire image so no area looks sharper or softer than another sharpen fine edges tree lines bricks vegetation detail rock texture pathways clarify subtle textures water ripples foliage grain soil variation architectural materials enhance micro shadows contact shadows soft ambient occlusion edges of natural forms refine human silhouettes while maintaining their original appearance and scale increase overall crispness without over smoothing or introducing noise strict preservation rules do not shift colors alter shadows change brightness or contrast beyond natural sharpness improvements warp or stretch geometry add new reflections textures or lighting styles remove grain or depth cues that belong to the original rendering the enhanced image should feel like the same image but rendered originally at 4k with high end photographic clarity
