Use the people from the reference image. Preserve facial features and keep the same face. **Concept:** A realistic ultra-high-resolution photo of a couple seen from behind in semi-profile against a colossal nuclear explosion. **Subject:** A man on the left and a woman on the right, based on the reference. **Setting:** A dark field with lavender flowers and dry grass stretching into deep perspective, with a massive mushroom cloud rising in the background. **Action & Pose:** The couple stands close together with their heads slightly tilted toward each other. Their hands are raised at chest level and joined into a heart shape, framing the stem of the mushroom cloud. Their gaze is directed straight into the center of the flash. **Appearance:** The man's hair matches the reference and is lit from above with a golden glow. The woman's hair is long, loosely wavy, falling over her shoulders, with each curl clearly defined and highlighted along the edges. Their faces are visible in semi-profile with calm expressions, relaxed cheekbones, and a faint half-smile conveying fatalism. **Wardrobe:** The man wears a dark blue heavy denim jacket with a pronounced twill texture. The woman wears a black ribbed knit top. A thin gold ring with a highlight is visible on the woman's ring finger. **Framing & Composition:** Centered composition, medium shot, shoulder-level angle. **Lighting:** Extremely intense backlight from the explosion epicenter creates a bright orange-golden halo around their silhouettes. Frontal heat subtly illuminates skin texture. **Camera & Optics:** 35mm focal length, f/2.8 aperture for natural depth of field, ISO 100 for minimal grain, 1/8000 sec shutter speed to freeze the flame dynamics. Vertical 9:16 format. **Visual Style:** Realistic photography with maximum sharpness. **Atmosphere:** Calm, fatalistic, awe-filled. **Color Palette:** Saturated spectrum, high contrast, warm white balance at 3200K. The explosion ranges from blinding white #FFFFFF to fiery orange #FF4500 and deep brick red #8B0000. The field includes lavender purple #9370DB. **Details & Texture:** The explosion is a multilayered structure of incandescent plasma, white noise in the core, and turbulent smoke masses. A double condensation ring forms around the cap of the blast with a soft gradient. The man's hands are tense, with visible knuckles and skin microrelief. Skin textures show pores and fine hairs. The distant smoke veil has soft bokeh. **Preserve:** Keep the identity and facial features of the people from the reference image. **Exclude:** Distortion. **Priority Instructions:** Maintain facial resemblance to the reference, preserve the exact two-person composition, and keep the heart-shaped hand gesture framing the mushroom cloud.
