Expand this vertical image horizontally to a 16:9 aspect ratio by generating new, photorealistic content exclusively on the left and right sides. The original central portion of the image must remain entirely unchanged: do not stretch, squash, compress, warp, resize, or alter its proportions, pixels, or aspect ratio in any way. The newly outpainted areas must perfectly match the original’s lighting, colors, perspective, depth of field, and textures. The final wide image should have no visible seams, and the original part should look exactly as it was, just with natural extended scenery on both sides.
