Step by step
- 1
Start with the subject
One clear sentence about what is in the picture: the product, the person or the scene. What you write first carries the most weight.
2Add the setting, light and framing
Where it is (studio, kitchen, street), how the light falls (soft, backlit, golden hour) and the shot (close-up, top-down, medium shot).
- 3
Use references
Upload up to 14 images: the product photo, a face or a style. References pin down what text can't describe exactly.
- 4
Save a character
Create a character once (4 credits) and write its @handle in any prompt to keep the same face.
- 5
Pick the size and format
Sizes 1K, 2K, 4K and formats 1:1, 3:4, 4:3, 2:3, 3:2, 9:16, 16:9, 21:9. Generate up to 4 images per batch and keep the best one.
Example prompts
Swap the subject and keep the structure: subject, setting, light, framing, style.
Product
Glass perfume bottle on wet stone, dark background, soft rim light, close-up, commercial photography.
Portrait
Portrait of a woman in her thirties in a café, natural window light, medium shot, shallow depth of field, editorial style.
Character
@your-character walking down a Tokyo street at night, neon signs, medium shot, cinematic look.
Common mistakes
Asking for too much at once: one idea per image works better.
Describing a face only in words when you want the same person in several images: use a reference or a saved character.
