    ultra-realistic cinematic photograph, 9:16, full body dynamic shot, a young woman joyfully
    spinning in shallow water near a fountain, body slightly turned mid-motion with one hand lifting
    the flowing dress while the other moves naturally, soft joyful smile with relaxed expression,
    face lock: preserve exact facial features and identity, do not alter face or hairstyle, natural
    proportions, skin: soft natural skin with visible pores and smooth tonal transitions, subtle
    micro-texture with natural light reflection, hair: long loose wavy hair, slightly damp with
    dynamic motion, fine strands catching backlight glow, no over-styling, clothing: lightweight
    flowy dress in yellow and pink color combination, soft semi-transparent fabric with subtle
    floral texture, fabric reacting naturally to spin and water resistance, edges lifting with
    motion and partially sticking due to moisture, environment: outdoor fountain during golden hour,
    shallow water splashing around feet with droplets suspended mid-air, water ripples expanding
    outward in concentric patterns, background lush greenery softly blurred with strong sun rays
    piercing through leaves, lighting: warm golden hour backlight creating strong rim glow around
    hair and dress, soft frontal bounce light illuminating face, sparkling highlights on water
    droplets, subtle lens flare and light diffusion for cinematic depth, color: rich warm tones with
    golden highlights and natural contrast, lens: 85mm shallow depth of field with subject tack
    sharp and background creamy bokeh, realism: DSLR-quality, ultra-detailed, photorealistic,
    natural motion blur only on fastest moving edges, no stylization


    negative prompt: painting, oil painting, illustration, CGI look, plastic skin, over-smooth face,
    stiff fabric, frozen unnatural motion, oversharpening, flat lighting, distorted anatomy, extra
    limbs, blur, noise, text, watermark

notes: >
  3 unique test results · all PASSED:


  (1) 9:16 aspect ApiMart · FIRST validation · accepted directly (no fallback to 4:5)
      → unlocks vertical Reels/TikTok/Shorts formats on gpt-image-2

  (2) Negative prompt honor · STRONG effect · model honored:
      · no painting/CGI look (DSLR-realistic)
      · natural skin (no plastic) · pores visible
      · dynamic fabric (not stiff)
      · warm lighting (not flat)
      · no text/watermark
      → gpt-image-2 DOES respect negative prompt syntax

  (3) Face lock vs 'young woman' conflict · FACE LOCK WON (yuan_kid identity preserved · ~7yo
  apparent age)
      · slight age compensation (4yo ref → looks 7-8) but still child · NOT young woman
      · 'do not alter face or hairstyle' directive overrode subject anchor
      → OPPOSITE of porcelain test (where 'young woman' beat 'use for structure only')
      → directive strength wins · explicit imperative ('do not alter') beats descriptive ('use for structure only')

  (4) Photoreal aesthetic · DSLR-quality achieved · golden hour rim glow on hair · water droplets
      mid-air · 85mm bokeh background · skin pores visible · natural motion blur on dress edges
