Night mode on iPhone automatically activates in low-light conditions, and you can manually adjust or confirm it from the Camera app. Here’s a quick, practical guide: Direct answer

• Open the Camera app in Photo (or Portrait) mode. If lighting is low enough, you’ll see a moon-shaped icon (Night mode) appear at the top of the screen. This indicates Night mode is active. You can tap the icon to adjust the exposure time, then press the shutter to take the picture.

What to expect and how to use it

• Activation: Night mode generally turns on automatically when ambient light is poor on iPhone XS and later models (iPhone 11 and newer especially). If the icon isn’t visible, try switching to a different mode or tap the caret to reveal additional settings.

• Adjust exposure: After Night mode appears, swipe up or down on the Moon icon to adjust the capture time (amount of exposure). Longer exposure brightens the shot but requires steadiness. Typical ranges go from fractions of a second to several seconds, depending on lighting.

• Stability tips: To minimize blur during longer exposures, use a steady stance, rest the phone on a stable surface, or use a tripod. A brief pause after tapping the shutter helps the camera complete the exposure.

Common tips for better Night mode results

• Keep the iPhone as steady as possible; even small movements can blur long exposures. Use a tripod or place the phone on a stable surface when you can.

• Hold your breath or steady yourself during longer exposures to reduce shake.

• If you don’t see Night mode, ensure you’re in a compatible model (night mode is supported on iPhone 11 and newer) and that you’re in a low-light scenario. You can switch to a lower-light scene by adjusting the exposure time once the icon appears.

If you’d like, I can tailor these steps to your exact iPhone model (e.g., iPhone 13 vs. iPhone 15) and desired shot type (landscape, indoor, or portrait) with model-specific tips.
