Prompt
Place a single vintage tabletop radio as the sole subject within a vertical 2:3 frame, occupying roughly the lower-center third and filling about one-quarter to one-third of the image area to retain visible table surface and generous negative space above. Position the radio slightly left-of-center with its dial and textured grill facing three-quarter toward the viewer for clear detail and readable markings. Use product-photography treatment with eye-level viewpoint and a tight medium distance that emphasizes the radio's aged bakelite sheen, metal knobs with tiny patina, and woven speaker cloth texture. Light with a single soft, low-key source from the upper-right to create gentle side shadows and a warm rim on the radio edge while preserving deep charcoal background tones. Keep the wooden table surface crisp in the foreground with visible grain and subtle wear occupying the lower third, and let the background remain smooth gradient filling the upper two-thirds to frame the subject. Render shallow depth so the radio is sharp and foreground wood texture is moderately crisp while the background softens, and maintain warm brown and muted amber accents against a dark neutral backdrop.
