LTX 2.3 prompt examples

Oct 5, 202610

Read the full promptMedium shot from a low angle, close to the ground, looking up through a field of tall sunflowers. Big sunflower-yellow blooms with dark brown centers face the camera on thick moss-green stems, broad leaves in the same moss green below them, and a clear sky-blue sky above with a few small white clouds. A steady breeze moves through the field: the whole row of sunflowers sways gently to the right and back once, in one slow smooth movement. The camera stays still the whole time. Late morning, high sun overhead lights the petals evenly, with short soft shadows on the leaves and the ground. Everything from the front flowers to the far rows stays in focus. Simple large shapes: round flower heads, straight stems, flat blue sky. No people, no text, no logos, no watermark.

Read the full promptA bright refreshing commercial-style scene with assorted pastel-colored soda cans in soft mint, powder blue, butter yellow, and lilac tones descending and landing into a large glass bowl filled with sparkling ice cubes and chilled water. The cans drop gently but with realistic weight, one after another or together, settling into the ice with crisp splashes, bouncing ice pieces, shifting reflections, and droplets scattering in the air. Condensation glistens on the metal surfaces, fruit illustrations remain visible, and the bowl catches the light with glossy transparent highlights. The camera remains completely static, centered on the bowl, while only the cans, water, and ice move. Clean summer aesthetic, photorealistic liquid motion, bright natural light, highly detailed, cinematic 4K.

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.

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 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.

Apr 2, 2026300

Read the full promptA majestic dark silver-gray unicorn stands still on a rocky mountain peak at sunset, surrounded by dramatic distant mountains and a glowing sky filled with warm gold, peach, and dusky blue tones. The camera remains completely static. The unicorn gently blinks and slowly looks around from side to side with calm, noble, natural head movement, as if quietly observing the vast landscape. Its long flowing mane and tail stream continuously in the wind, moving softly and elegantly with layered strands catching the fading light. A faint mist drifts around the rocks near its hooves, and the horn glows subtly against the sky. The overall mood is magical, serene, and powerful, with realistic animal motion, graceful wind-blown hair movement, photorealistic, highly detailed, cinematic 4K.

Apr 2, 2026940

Read the full promptA cinematic static shot of a lone astronaut sitting on the stone edge of a long reflective pond in a sunlit Mediterranean courtyard with arches, climbing flowers, ivy-covered walls, and terracotta pots. The water is calm and dark, dotted with lily pads and soft pink water lilies. The astronaut remains seated in a quiet contemplative pose, gently and slightly swinging their legs over the water in a slow relaxed motion, causing only the faintest subtle disturbance near the surface. Warm golden-hour light washes over the old stone architecture and softly reflects in the pond. The atmosphere feels peaceful, surreal, and poetic, with no camera movement, only the small natural motion of the astronaut's legs. Photorealistic, highly detailed, cinematic 4K.

Oct 5, 202600

Read the full promptA glossy orange plastic fox figurine with simple rounded shapes sits on a smooth electric-blue backdrop, close-up. The fox slowly lowers its head in one gentle nod and lifts it back to the start. A white plastic pedestal under its feet echoes the white tip of its tail. Soft light from a large softbox on the left, a clean highlight on the glossy orange. The camera stays still. No text, no logos, no watermark.
