Night mode on iPhone automatically activates in low-light scenes, and you can control it directly from the Camera app. Here’s how to use it effectively and what you can tweak: Direct steps

• Open the Camera app and switch to Photo mode (or keep it in Photo mode if you’re already there).
• In low light, a moon icon labeled Night Mode appears near the top left (or near the shutter button, depending on model). If the icon is yellow, Night Mode is active; if it’s faded, Night Mode isn’t engaged yet. Tap the Night Mode icon to enable or disable it as needed. The camera may turn on Night Mode automatically in very dark settings.
• Use the on-screen slider (above the shutter button) to adjust the capture time. Longer exposure (e.g., 2–30 seconds, depending on model and light) can brighten the shot, but requires the phone to stay very still. A longer time yields brighter, cleaner night photos, while a shorter time reduces motion blur.

Tips for getting better results

• Stabilize the phone: Use a tripod or rest the iPhone on a stable surface to avoid blur during longer exposures.
• Tap to focus: Tap the area you want in focus before taking the shot, then hold your phone steady.
• Use a timer: If you don’t have a stable surface, use the camera timer to reduce shake when you press the shutter.
• Turn off Live Photos if you don’t need motion: Live Photo can blur long exposures in Night Mode; turning it off helps.
• Explore finer controls: On supported models, you can tap Camera Controls to manually adjust Night Mode exposure options and preserve those settings for subsequent shots.

What to expect by model

• Night Mode is available on iPhone models with the camera; on older devices, Night Mode may be limited or unavailable. If Night Mode is not visible, your device may not support it, or you may need to update iOS to a version that includes Night Mode in the stock Camera app.
