An honest approach
A good dating photo is natural, understandable and recognizable. It's better to fix hard lights, noisy backgrounds and bad composition than create a person who isn't there.
This is a separate task from business photography: friendliness, naturalness and lively background are important here, not an office portrait.
What to include in the prompt
- Maintain face, age and natural expression
- Improve light and background without strong retouching
- Make a friendly portrait that looks like a real photo.
How to get a reliable result for dating
Start with one clear source image and one main change. Name the face, object, angle or color that must remain unchanged.
For a complex idea, split the work into steps and compare the first result before launching a full series.
