LTX 2.3 prompt examples

Oct 5, 2026120

Read the full promptA businesswoman in a white blazer walks at an even pace along a glass-walled office gallery, seen in a medium side shot. Sage-green panels line one side, an ochre wooden floor runs beneath her, white walls fill the far end. Daylight pours down from a skylight above her head and lays soft bright bands across the floor. The camera tracks smoothly alongside at her pace, nothing else moves. No text, no logos, no watermark.

Read the full promptA pastel dreamy close-up of a translucent retro handheld game-console-shaped aquarium standing on a soft light surface, with milky iridescent plastic, coral-pink buttons, and clear turquoise water inside. The camera remains completely static. Small colorful fish swim naturally inside the tiny aquarium, moving gently in different directions around delicate aquatic plants, smooth white stones, and small driftwood pieces. The water surface shows slight soft movement, and the whole scene feels calm, whimsical, and serene. Bright diffused lighting, soft pastel background, subtle reflections, photorealistic, highly detailed, cinematic 4K.

Apr 2, 20263970

Read the full promptA cinematic first-person view of a person riding a vintage bicycle down a narrow country road through rolling green hills at golden sunset. The viewer sees both hands holding the handlebars and a fresh bouquet of wildflowers fixed to the front of the bike, with daisies, poppies, grasses, and small blue blossoms gently moving in the wind. The bicycle moves steadily forward along the winding road, creating a smooth immersive POV sensation. Meadows blur softly at the edges from motion, small countryside houses and distant mountains appear ahead, and the warm sun glows near the horizon under a dramatic pastel-orange and pink sky. Natural forward motion, subtle handlebar vibration, flowers lightly swaying, dreamy rural atmosphere, photorealistic, highly detailed, cinematic 4K.

Read the full promptA cinematic underground parking garage scene with a young woman leaning against a graffiti-covered silver tuner car under cold greenish fluorescent lights. The camera smoothly slides to the right in a slow stylish lateral tracking shot, creating parallax between the girl, the car, the wet concrete floor, and the dark parked vehicles in the background. As the camera moves, the girl poses subtly for the camera with relaxed editorial attitude: a slight shift of posture, small change in head angle, calm change of gaze, and minimal body movement while staying leaned against the car. The car remains still, reflections glide across its metallic surface, and the whole atmosphere feels moody, urban, rebellious, and cinematic. Photorealistic, highly detailed, stylish street-fashion energy, cinematic 4K.

Oct 12, 202630

Read the full promptA wildlife documentary shot of an adult male lion with a thick dark-tawny mane walking steadily through tall savanna grass from right to left. The camera is placed low, close to the ground, and stays still. Pale straw-yellow grass blades stand in the foreground, the lion walks at medium distance with his whole body in view and his head held level, gaze ahead. His coat is a sandy tawny color against a clear blue sky with a few thin clouds. Low evening sun from the side lights the edge of the mane and the grass tips, and long soft shadows lie across the ground. A single flat-topped tree stands far behind him. The grass sways in a light breeze. No people, no vehicles, no text, no logos, no watermark.

Apr 2, 2026801

Read the full promptA cinematic luxury night scene at a modern poolside villa, with a glamorous woman posing on the roof of a partially submerged silver car glowing with neon cyan and pink reflections from inside the cabin. The camera remains completely static, with no movement at all, keeping the woman centered as the focal point. She poses confidently for the lens with slow sensual editorial movements: a slight shift of her torso, a graceful change in head angle, subtle eye contact, soft hair movement, and elegant repositioning of one arm and leg. The water around the car remains calm with faint ripples and shimmering reflections, while droplets on the windshield and bodywork catch the light. The atmosphere feels moody, stylish, luxurious, and slightly surreal, with high-fashion energy, neon reflections, photorealistic detail, highly detailed, cinematic 4K.

Read the full promptA grey heron stands knee-deep in calm water at the edge of a reed bed, tall and upright, neck folded in a gentle S-curve, beak angled slightly down. It lifts one leg and takes a single slow step forward, then settles and stands still. Wide shot from a low angle close to the water, the whole bird and the far bank in focus. The water is flat pewter grey, the reeds are olive green, and a thin band of dusty rose sits on the horizon under a pale grey sky. Soft diffused light from a thick overcast sky, no sun and no hard shadows. The camera stays still. Quiet wildlife documentary look, large simple shapes, smooth plumage. No other animals, no people, no text, no logos, no watermark.

Apr 2, 20261330

Read the full promptA cinematic rainy night street scene with a couple in love standing close together under heavy rain on a neon-lit city corner, holding each other's hands tightly as if they have just run to one another from opposite ends of the street. Their bodies are still slightly tense from the rush, shoulders rising and falling with visible breathlessness, chests moving as they catch their breath, damp hair clinging to their faces, clothes soaked through by the rain. They stay close, emotional and intimate, looking at each other with a mix of relief, longing, and urgency. Rain pours hard around them, water splashes on the pavement, neon reflections shimmer across the wet street, and the atmosphere feels romantic, dramatic, and electric. Subtle realistic breathing, slight trembling from exertion, hands held firmly, cinematic lighting, photorealistic, highly detailed, emotional realism, cinematic 4K.
