The quick answer
Open Settings, Camera, Preserve Settings and enable only the controls you want Camera to remember. Then make the desired choice in Camera itself and check it after reopening. The preserve switch retains a choice; it does not choose that mode or effect for you. Options depend on the iPhone model and software.
Separate a remembered setting from a preferred setting
Apple lists preservation controls for items including Camera Mode, Live Photo, Exposure Adjustment and, on supported models, Night Mode. Think of preservation as remembering the previous choice, not defining one permanent preset for every situation.
For example, retaining the last camera mode can be helpful during a portrait session. It can also leave you opening a mode you used briefly for a different task. Decide whether continuity or a fresh starting point is more useful for each control.
Change one setting and verify it
Go to Settings, Camera, Preserve Settings. Pick one available control rather than switching everything on.
Open Camera and make the choice you want remembered. For a Live Photo preference, set Live Photo itself on or off in Camera after enabling preservation.
Leave Camera and reopen it. Check the indicator or mode before taking another picture. Record what was retained on your own phone.
If the result is useful, configure the next control. If it causes surprises, turn off preservation for that control and check Camera’s behavior again.
Choose according to the photographs you take

Situation
Decision to make
You repeatedly return to the same capture mode
Consider preserving Camera Mode; check it before an unrelated shot.
You have a deliberate Live Photo preference
Preserve that preference, then choose its state in Camera.
You often brighten or darken a specific scene
Decide whether retaining exposure adjustment will help the next scene or confuse it.
You occasionally disable Night mode
Choose whether that last decision should carry forward on a supported phone.
Do not confuse exposure memory with focus lock
Apple’s camera-tools guide separates exposure adjustment from tapping a subject to focus. Its exposure control can be preserved through the Exposure Adjustment setting. That is not a promise that the same person or object remains in focus after you reopen Camera.
Imagine darkening a bright window scene, then opening Camera later in a dim room. Before blaming the new room or an editing app, inspect the exposure control you chose to preserve. Compare a frame with that adjustment and one with it reset. Keep the version that preserves the details you need; do not reuse the same correction merely for consistency.
Our related AE/AF Lock guide explains focus and exposure during a shot. Use that capture control for the current scene, and use Preserve Settings to decide what should persist between sessions.
When an option is missing or behavior differs
Apple marks several preservation features as model-dependent. Check the guide for your iOS version and the controls actually present on the phone. A missing option does not by itself establish a fault.
Keep troubleshooting narrow: note the model, iOS version, control name, desired state and state after reopening. Test in Apple’s Camera app. A camera inside another app may have its own controls, so do not use that result as proof that the system Camera ignored your preference.
Before an important session, take a quick ordinary photograph and inspect it. Verify mode, framing and the controls you intentionally kept. This small preflight is more useful than a long list of “best settings” that does not match your work.
Common questions
Should I turn every Preserve Settings option on?
There is no single best setup. Keep the choices you regularly want, and leave yourself a predictable starting point for everything else.
Will these switches change old photos?
These are camera capture preferences. To change an existing photograph, use an editing workflow and keep its original available.
