How to Write Effective Prompts
The Prompt is an important part of using Prompt Edit. You should clearly describe what you want to change and which elements should remain unchanged.
1. Clearly Describe What You Want to Change
Specify exactly which part of the image you want to change.
For example:
Transform the background into a sophisticated blue-hour cityscape.
2. Describe the Style and Atmosphere
You can add the desired style, lighting, colors, or atmosphere.
For example:
Create a cinematic blue-hour atmosphere with realistic city lights and reflections on the water.
3. Specify What Should Remain Unchanged
If you do not want AI to change the main subject or important details, clearly state this in your Prompt.
For example:
Preserve the original subject completely unchanged.
4. Combine Multiple Requirements
You can combine multiple requirements in a single Prompt to describe the desired result more clearly.
For example:
Transform the background into a natural blue-hour cityscape with realistic city lights and reflections on the water. Preserve the original subject completely unchanged and maintain realistic depth of field.
5. Use Suggest Prompt When Needed
If you are not sure how to create a Prompt, you can use Suggest Prompt to get suggestions.
Then, review and adjust the content so that the Prompt matches your image and the result you want.
Tips for Better Results
1. Describe Your Request Specifically
Instead of using a very short or general Prompt, clearly describe what you want AI to do.
2. Clearly Define the Area to Edit
If you only want to change part of the image, clearly describe the area to help minimize changes to other parts of the image.
3. Describe the Desired Style
You can add elements such as visual style, lighting, colors, atmosphere, or depth of field to achieve a result that better matches your expectations.
4. Specify What Should Remain Unchanged
If you want to preserve the subject, face, clothing, or other important details, include these requirements directly in the Prompt.
5. Save Frequently Used Prompts
For Prompts that you may use repeatedly, click Save prompt to save them.
You can find and reuse saved Prompts in Saved prompts during future editing sessions.
6. Check Before & After Before Exporting
After AI finishes processing, compare the original and edited images to make sure the result matches your request and important details are preserved.
