Fitness Before/After Ad (Split-Screen Light Contrast)
The cold-versus-warm lighting contrast tells the transformation story before anyone reads a word, and the reserved top and bottom strips mean your headline and CTA drop in cleanly without fighting the photo.
prompt
Create a split-screen before/after fitness ad for {gym_name}. Left half: a {subject_description} in loose grey workout clothes, slouched posture, flat cool-toned lighting against a plain concrete wall. Right half: the same person standing tall in fitted athletic wear, confident expression, warm dramatic side lighting — visually celebrating {transformation_goal}. Divide the frame with a clean vertical seam and a bold {accent_color} diagonal slash element. Photorealistic, 85mm portrait-lens look, vertical 4:5 ratio for feed ads. Keep the top 15% clean for a headline overlay and leave a slim bottom strip empty for a CTA button. No text baked into the image.
