The built-in Photos app on iPhone has come a long way, but it still has limitations when it comes to complex background editing. Fortunately, with the release of iOS 16, Apple introduced a game-changing feature called “Lift Subject,” which allows users to easily separate a subject from its background. For more advanced editing needs, there’s a wealth of third-party apps available that offer powerful tools for background manipulation.
In this article, we’ll explore both the built-in “Lift Subject” feature and recommend some top-notch third-party apps. We’ll provide step-by-step instructions, practical tips, and insights to help you achieve professional-looking results right from your iPhone.

Adding Background Using the Built-in “Lift Subject” Feature (iOS 16 and Later)
Apple’s “Lift Subject” feature, introduced in iOS 16, uses advanced machine learning to identify and isolate the main subject of a photo. This technology can save you significant time and effort in separating a subject from its background.

Here’s how to use it:
- Open the Photos app and select the picture you want to edit.
- Long-press on the main subject in the photo. You’ll notice the subject flash with white edges, indicating that the iPhone has recognized it.
- Tap “Copy” to copy the subject with a transparent background.
- (Optional) You can now paste the subject directly into another app like Notes or a messaging app.

Limitations of Lift Subject and How to Overcome Them
While this feature is incredibly useful, it does have some limitations. It works best with well-defined subjects and solid backgrounds. Complex backgrounds or subjects with intricate details may not be as accurately identified.
If you’re having trouble with the “Lift Subject” feature, try these troubleshooting tips:
- Ensure good lighting: The feature works better with well-lit photos.
- Use contrast: A subject that contrasts well with the background is easier for the AI to identify.
- Try different angles: Sometimes, slightly adjusting your finger position when long-pressing can yield better results.
Third-Party Apps for Advanced Background Editing
For more precise control and advanced editing options, third-party apps are the way to go. These apps offer a range of tools that can help you achieve professional-looking results. Here are some top recommendations:
- Superimpose X (Paid – $4.99)
- PhotoRoom (Free with in-app purchases)
- Photoshop Express (Free with in-app purchases)
- Enlight Photofox (Free with in-app purchases)
- BackgroundErase (Free with in-app purchases)
Let’s take a closer look at one of these apps: Superimpose X. This powerful tool offers a range of features for background editing and image compositing.
Step-by-Step Guide to Using Superimpose X
- Download and launch Superimpose X from the App Store.
- Tap the “+” button to import your foreground (subject) image.

- Refine your selection with the “Brush” tool, using the “Erase” and “Restore” options to fine-tune edges.
- Adjust your foreground image’s size, position, and rotation to fit the new background.
- Use blending modes and opacity adjustments to integrate the subject naturally with the background.
- Apply color adjustments to match the lighting and tone of the background.

Tips for Achieving Professional-Looking Results
- Lighting matters: Ensure the lighting of your subject matches the new background. Use adjustment tools to tweak brightness, contrast, and color temperature.
- Pay attention to edges: Spend time refining the edges of your subject for a seamless blend with the new background.
- Consider perspective: Make sure your subject’s size and angle match the perspective of the new background.
- Use shadows: Adding a subtle shadow can help ground your subject in the new background, making it look more realistic.
- Color grading: Apply a consistent color grade to both the subject and background to unify the image.
