02Step-by-Step Guide
1

Upload Image to an Editing Tool

Take the generated image from Midjourney that needs fixing and upload it into an AI editing tool like Nano Banana or Flora.

2

Mask the Area to Change

Using the tool's interface, select or 'mask' the specific part of the image you want to edit, such as an incorrect object, distorted feature, or other detail.

3

Prompt the Change with Specific Instructions

Write a very specific, descriptive prompt to replace the selected area. Be explicit about what you want to add and what should remain the same to guide the AI accurately.

Prompt:
replace the computer she's typing on, on a 2026 midnight Black MacBook Pro. keep the position and the size of the computer exactly the same. only the left side and the keyboard is visible
Pro Tip: Add a constraint like 'don't change anything else' to your prompt to ensure the rest of the image stays consistent during the edit.
