Realistic product photography, a single brown hardboard clipboard standing vertically and slightly tilted to the right, with a silver chrome metal spring clip centered at the top, a black pressure bar, a round hanging hole, rivets and embossed lettering on the clip, and subtle scratches, creases and wear marks on the board. Clean white background, no people, no other objects, oblique top-down close-up, the whole single object centered, neutral cool white lighting, emphasizing metal reflections and brown fiberboard texture, aspect ratio approximately 3:4.
