Extreme macro of grey wet clay bearing a clear pressed fingerprint, every ridge of the print held in the damp surface, tiny drag marks where the finger lifted away, low raking light so each ridge reads as relief. An extreme macro photograph in which the material itself is the entire subject — no object, no scene, no story. Raking side light so that texture reads as relief. Fills the whole square frame, edge to edge, with the surface only. No human faces in frame. If hands appear they are ordinary working hands with five normal fingers, correctly proportioned, and fully clothed forearms. No text, no letters, no numbers, no signage, no logo and no watermark anywhere in the image. Do NOT include any real company logo, real brand name or real trademark.
