1. A product photograph with useful negative space
Use case: product-mockup. Create a landscape 3:2 premium studio product photograph of one squat amber glass bottle on a pale limestone plinth. The bottle has a matte cobalt-blue cylindrical screw cap and a small cream paper label reading exactly "STILL" in black uppercase serif letters, once only. The bottle stands on the right half, with generous empty warm ivory background on the left. Soft daylight enters from the upper left, creating one believable shadow to the right. Show subtle glass reflections, fine stone pores, and a crisp label. Camera at bottle height, natural proportions. No other objects, no extra text, no watermark.

2. An event poster with exact wording
Use case: ads-marketing. Design a portrait 2:3 editorial poster for a fictional evening food market. Use a warm ivory paper background, deep navy typography, one large vermilion circle, and a restrained navy line illustration of a noodle bowl in the lower third. Make the layout bold and spacious with a clear typographic hierarchy. Render exactly these three lines, each once: "NIGHT MARKET" as the large headline at the top; "SATURDAY, 6–10 PM" beneath it; "RIVER HALL" at the bottom. All lettering must be sharp and readable. Flat printed graphic design with slight paper texture, no frame, no other words, no logos, no watermark.

3. A portrait where hands have a job
Use case: photorealistic-natural. Create a portrait 2:3 candid editorial photograph of a fictional middle-aged ceramicist in a quiet pottery studio. Frame from the waist up at eye level. She looks down at one small unfinished clay bowl held gently in both hands at chest height; all fingers should have believable anatomy and contact with the bowl. She wears a faded indigo apron, with a little clay dust on her fingertips. Soft window light from the left, natural skin pores and fine lines, shelves of unfocused pottery behind her. Subtle film grain, honest colors, no beauty retouching, no cinematic color grading, no text or watermark.

4. A busy scene with countable constraints
Use case: photorealistic-natural. Create a landscape 3:2 photograph of a small neighborhood cafe on a rainy afternoon, viewed at eye level from inside near the entrance. Show exactly five adults: one barista behind the counter on the left pouring coffee into a white cup; two friends seated opposite each other at the central table, one holding an open book; one customer by the window on the right closing a yellow umbrella; and one customer at the rear picking up a paper bag. Keep their bodies separate and their actions readable. The central table has exactly two cups. Warm pendant lights mix with cool window daylight, with believable wet-street reflections outside. Natural documentary photography, no dramatic color grading, no readable signs, no extra people or people in reflections, no watermark.

5. A four-panel comic with a recurring character
Use case: illustration-story. Create one square comic page in an exact 2-by-2 grid with four equal panels, read left to right then top to bottom. Use clean ink outlines, muted gouache colors, and cream paper. The same small friendly robot appears in every panel: rounded teal rectangular body, two short legs, two mitten-like hands, two round yellow eyes, and one short antenna on the left side of its head. Panel 1: the robot puts one seed into a small terracotta pot. Panel 2: it waters the same pot with a tiny yellow watering can. Panel 3: it leans close to examine one tiny green sprout in the pot. Panel 4: it sits proudly beside the same pot, which now contains one large sunflower. Keep the robot design and simple windowsill setting consistent. Clear panel borders, no speech balloons, no text, no watermark.

6. Change one color and preserve the product
Use case: precise-object-edit. Image 1 is the product photograph to edit. Change only the matte cobalt-blue bottle cap to matte burnt orange. Preserve the cap geometry and texture, amber glass, cream label and the exact word "STILL", bottle position, limestone texture, reflections, shadow, background, lighting, crop, and dimensions. Do not add or remove anything. Keep every other detail unchanged.

7. Make a simple sketch to use as an input
Use case: stylized-concept. Create a landscape 3:2 rough graphite pencil concept sketch on plain white paper of a minimal reading corner, with no color and no text. Show exactly three furniture objects in a coherent three-quarter perspective: a low lounge chair centered slightly left with one rectangular back cushion, one seat cushion, a simple exposed wooden frame and four legs; a small round side table to its right on a single pedestal; and a slender floor lamp behind the table with a conical shade and round base. Include the floor-wall corner as two faint lines. Leave the rest of the room empty. Loose exploratory hand-drawn strokes, clear silhouettes, no annotations, no people, no plants, no books, no watermark.

8. Turn the sketch into a furnished corner
Use case: sketch-to-render. Image 1 is the generated pencil sketch to use as the layout reference. Turn this sketch into a photorealistic interior photograph. Preserve the exact camera angle, relative positions, proportions, chair frame geometry, cushion shapes, round side table, lamp silhouette, and floor-wall corner. Use natural oak for the chair frame and table, oatmeal linen for the cushions, brushed brass for the lamp, warm white plaster walls, and a pale oak floor. Soft daylight from the left. Keep exactly these three furniture objects. No people, plants, books, extra furniture, text, or watermark.

9. A food photograph with restrained styling
Create a square editorial food photograph of one slice of lemon cake on a plain white ceramic plate, with one small fork to its right. Use a pale blue linen tablecloth, soft morning window light from the left, and a slightly overhead camera angle. Show moist crumb texture and a thin layer of icing. Keep the styling simple: no flowers, fruit props, extra plates, text, or watermark.

10. A travel illustration with room for a title
Create a landscape 3:2 watercolor travel illustration of a quiet canal in Amsterdam at dawn. Show narrow brick houses, one arched bridge, and two bicycles parked along the railing. Use muted terracotta, blue-gray water, and warm paper texture. Keep the upper quarter mostly pale sky for a title to be added later. No lettering, logos, crowds, or watermark.

11. A transparent shop asset
Create a square product cutout of one original mint-green over-ear headphone design, viewed at a three-quarter angle with both earcups visible. Use matte plastic, soft woven cushions, and subtle metal hinges. Center the complete object with generous padding on a fully transparent background. No brand name, text, solid backdrop, checkerboard pattern, scenery, or shadow.

12. Replace a background while keeping the subject
Image 1 is the product photo to edit. Replace only the background with a seamless pale sage studio backdrop. Preserve the product's exact geometry, position, scale, colors, surface texture, label wording, and camera angle. Keep the lighting direction consistent and retain a believable contact shadow. Do not add props, text, logos, or a watermark.
