How to Add the Depth Effect to Any Wallpaper
Enable the Depth Effect on your iPhone lock screen in about a minute. Exact steps for iOS 16 through 26, plus fixes for Perspective Zoom cropping.
The Depth Effect is the trick that makes your lock screen look layered: part of the subject in your photo rises in front of the clock, so the time tucks neatly behind it. It is one of the most-liked features Apple added in iOS 16, and the good news is you do not enable it with a switch. iOS turns it on automatically when your wallpaper has a subject it can isolate. Your real job is choosing the right image and avoiding the few things that break it.
What the Depth Effect actually needs
iOS uses on-device machine learning to find a clear foreground subject — a face, a pet, a building, a bottle — and separate it from the background. For the layering to look good, three things have to line up:
- A distinct subject. Photos with one clear focal point work. Busy patterns and flat gradients give iOS nothing to lift forward.
- Headroom near the top. The subject needs to overlap where the clock sits. If the subject is centered low in the frame, there is nothing to rise in front of the time.
- Enough resolution. A small or heavily compressed image makes the cutout edge look rough.
This is a different effect from Perspective Zoom (the slight parallax when you tilt the phone) and from Live wallpapers. Depth is purely about that front-of-clock layering on a still image.
Setting it up step by step
- Long-press an empty area of your lock screen to open the editor, then tap the + button. On older setups you can also go to Settings > Wallpaper > Add New Wallpaper.
- Choose Photos and pick an image with a strong subject, or tap Photo Shuffle if you want a rotating set.
- In the editor, pinch and drag to position the subject so it overlaps the clock area. This is the single most important step — iOS only applies depth when there is meaningful overlap.
- If iOS detected a subject, the Depth Effect is already on. You will see the clock slip behind the subject.
- Tap Add, then choose Set as Wallpaper Pair to apply it to both screens.
Toggling it on or off manually
When the effect is available, tap the three-dot (•••) menu in the bottom-right of the lock screen editor. You will see Depth Effect as an option you can check or uncheck. If the option is greyed out, iOS could not find a usable subject — try repositioning the image or pick a different one.
A good source image matters more than any setting
You can shoot your own subject with Portrait mode for clean edges, but you can also start from a high-resolution wallpaper built for this. In Wallpaper Hub the still collections are full 4K with clear subjects, which gives iOS plenty to work with. If you want something one-of-a-kind, the AI generator can create a portrait-style image with a single bold subject — exactly the kind of frame the Depth Effect loves. Once you have an image you like, save it to Photos and follow the steps above.
For a particular mood, browsing by style helps: a dark image with a bright subject creates strong contrast against the clock, while a minimalist shot with lots of negative space gives you room to push the subject up into the clock zone.
Common reasons it does not work
The clock stays in front of everything. That means iOS did not enable depth. Reposition so the subject clearly overlaps the time, or the subject may simply be too flat for iOS to isolate.
The three-dot menu has no Depth Effect option. The current image has no detectable subject. Swap in a portrait-style photo with one obvious focal point.
Depth turns off when you add widgets. This is expected. iOS disables the Depth Effect automatically when lock screen widgets would overlap the subject, because both can’t occupy the same space. Remove the widgets, or accept that depth and a full widget row don’t coexist on the same screen.
The cutout edge looks jagged. Your source image is too low-resolution or over-compressed. Use a larger original — ideally 1290 × 2796 or higher.
Frequently asked
Does the Depth Effect work with Live wallpapers?
No. Depth applies to still images only. If you want motion instead, set a live wallpaper — but you cannot have both the layered clock and a moving background on the same screen.
Which iPhones support it?
Any iPhone running iOS 16 or later, all the way through iOS 26. It is a software feature, not tied to a specific camera or chip.
Why did my widgets cancel the effect?
iOS treats the area around the clock as shared space. Widgets sit there, so adding them switches depth off to avoid overlap. It is a trade-off, not a bug.
Wrapping up
The Depth Effect rewards a good photo more than any menu. Pick an image with one clear subject, nudge it up so it overlaps the clock, and iOS handles the rest. When you want fresh material to try it on, Wallpaper Hub has both a large 4K still library and an AI generator built for single-subject shots.
