How to Write Effective AI Background Replacement Prompts

Crafting a good prompt for AI Background Replacement requires a different mindset than creating an illustration from scratch. The focus is on precision, control, and command.

• Lock Your Subject: This is the most crucial rule. To prevent the person or object from changing, you must explicitly command the AI to keep them fixed. Always include a phrase like, "but keep the person in the exact same position, scale, and pose."
• Preserve Identity and Perspective: When editing photos of people, add another layer of protection by stating, "keep their face and identity the same." Furthermore, to maintain the original shot's integrity, command the AI to "not change the camera angle."
• Describe the New Scene Vividly: While you command the action, you still need to describe the new destination. Be specific. Is it just a "beach," or a "sunny beach with calm turquoise water and white sand"? The more detail, the better the result.

Your New Scenery Awaits

As you've seen, successful AI background replacement is all about precision and control. The secret lies in giving clear commands: lock your subject in place, preserve their identity, and vividly describe the new scene you envision.

The examples above are just the beginning. The best way to become an expert is by experimenting. Take these prompts, head over to Dreamface, and start creating your own amazing photo edits for free.
