1
Provide the source
Start with an image, video, or other visual asset that you have the right to use. Clear subjects and adequate quality usually make the intended change easier to judge.
2
Define the change
Choose the type of revision you want, such as changing a face, improving an image, or replacing a background. The clearer the goal, the easier it is to evaluate the output.
3
Review the result
Compare the revised version with the original, look for unwanted changes, and keep only an output that matches your purpose and respects the people represented.
