Image examples: generate, then edit
Four examples covering product photography, reference edits, poster typography and interior composition. Prompts are in English; open an image to inspect it at full size.
1. Generate a product image
An original studio product photograph of a handmade speckled coral ceramic teapot, gently asymmetric trapezoid body, tiny mint green loop handle and short curved spout. Three little navy dots on the lid. Warm ivory seamless background, soft side lighting, no lettering or logos.
Describe the material, shape, colors and lighting together. Use the generated image as the reference for the next step.
2. Edit the color using a reference
Preserve this exact original teapot shape and mint handle. Change only the teapot body glaze to deep cobalt blue, on the same neutral studio background.
Upload the first image, then use this edit prompt. Compare the shape and handle. The lid dots also changed color; explicitly ask to preserve their navy color in a further edit if that detail matters.
3. Create a poster with readable text
Create a vertical 2:3 travel poster of a red cabin in snowy mountains at sunrise, in a layered paper-cut illustration style with subtle paper texture. Place the exact headline "WINTER ESCAPE" at the top on two lines in large, clear uppercase lettering. Keep the cabin in the lower half, with a winding path, pine trees and mountain peaks. Leave generous open space around the text. Use warm sunrise light against cool blue snow. No other words, logos, frames or watermarks.
State the exact words, their position and the space around them. Start with a short headline and check every letter in the result.
4. Compose an interior scene
Create a photorealistic 3:2 interior photograph of a quiet reading room overlooking a leafy garden through floor-to-ceiling windows. Include warm plaster walls, an oak floor, a cream linen armchair, a low walnut table, a single closed book and a ceramic vase with a leafy branch. Use an eye-level 28mm architectural view with straight vertical lines, soft late-afternoon window light and natural shadows. Show believable linen, plaster and wood textures. No people, text, logos, exaggerated distortion or glossy CGI surfaces.
Specify the camera angle, furniture, materials and light together. Check window lines, furniture proportions and shadows before refining the image.
