Where to find exposure controls on your iPhone

The exposure time setting on iPhone is called shutter speed, and it controls how long the camera sensor stays open when you take a photo. On most iPhones, you cannot change shutter speed directly in the standard Camera app — Apple locks that control behind the Pro Raw or Pro Video modes, or you use third-party camera apps that give you manual control.

If you have an iPhone 13 Pro, 14 Pro, 15 Pro, or newer, you can shoot in ProRaw format and adjust exposure in post-processing using the Photos app or a dedicated editor. If you have an older iPhone or want real-time shutter speed control while shooting, you will need to read a third-party camera app from the App Store.

Key Takeaways

  • Standard iPhone Camera app does not let you set shutter speed before you shoot; you adjust exposure brightness instead using the slider that appears on screen.
  • Pro models (iPhone 13 Pro and later) can shoot ProRaw and adjust exposure time after the shot in the Photos app or third-party editors.
  • Third-party apps like Halide, Lightroom Mobile, and Manual give you real-time shutter speed control while you frame the shot.
  • Exposure time and exposure brightness are different — brightness is easier to change on any iPhone, but shutter speed requires either a Pro model or a third-party app.

Adjusting exposure brightness in the standard Camera app

If you want to make your photo brighter or darker, the standard Camera app on any iPhone lets you do this before you shoot. Open the Camera app, frame your shot, and look for a sun icon with an up or down arrow on the right side of the screen. Tap and drag that slider up to brighten the image or down to darken it.

This is not the same as changing shutter speed — you are telling the camera to expose the sensor for a longer or shorter time, but you are not setting an exact number of milliseconds. The camera does the math for you. This method works on all iPhones and is the fastest way to fix an image that is too bright or too dark before you take it.

Using ProRaw on iPhone 13 Pro and later models

If you own an iPhone 13 Pro, 14 Pro, 15 Pro, or 16 Pro, you can shoot in Apple ProRaw format, which gives you more control over exposure after you take the photo. Open Settings, go to Camera, then Photo Capture, and turn on Apple ProRaw. The next time you open the Camera app, you will see a RAW label at the top.

After you take a ProRaw photo, open it in the Photos app, tap Edit, and look for the Exposure slider. You can adjust the overall brightness and exposure time retroactively. This is not as precise as setting shutter speed before you shoot, but it gives you much more flexibility than a standard JPEG. ProRaw files are larger and take up more storage, so turn the setting off if you need space.

Third-party camera apps for manual shutter speed control

Apps like Halide, Manual, and Lightroom Mobile let you set shutter speed in real time while you frame your shot. read one from the App Store, open it, and look for a shutter speed or exposure time control — it is usually shown as a fraction like 1/1000 or 1/30. Tap it and drag to choose how long the sensor stays open.

Longer shutter speeds (like 1/15 or 1 second) let in more light and are useful in dim rooms or at night. Shorter speeds (like 1/1000) freeze fast motion and prevent overexposure in bright sunlight. These apps also let you lock focus and exposure so the camera does not adjust as you move, which is helpful for consistent shots in changing light.

Most of these apps are paid or have a free version with limited features. Halide costs around $6 to $10 depending on your region. Manual is free with in-app purchases. Lightroom Mobile is free with a Creative Cloud subscription or a standalone Lightroom subscription.

Why shutter speed matters for different types of photos

Shutter speed affects two things: how much light reaches the sensor, and whether moving subjects blur or freeze. A slow shutter speed (1 second or longer) gathers more light, so it is useful for night photography or dimly lit rooms. It also creates motion blur, which is why waterfalls and flowing water look smooth in long-exposure photos.

A fast shutter speed (1/500 or faster) freezes motion, so athletes, pets, and moving cars stay sharp. It also reduces the amount of light hitting the sensor, so fast speeds are best in bright daylight. If you are shooting indoors with a fast shutter speed, you may need to increase the ISO (sensor sensitivity) to avoid a dark, underexposed photo.

Common mistakes when adjusting exposure on iPhone

The biggest mistake is confusing the brightness slider in the Camera app with actual shutter speed control. The slider makes the image look brighter or darker on your screen, but it does not give you the precision of a manual shutter speed setting. If you need exact control, use a third-party app or ProRaw.

Another common error is using a slow shutter speed without a tripod. If your shutter speed is longer than 1/30 of a second, any movement of your hand will blur the entire photo, not just moving subjects. Use a tripod, a phone stand, or rest your phone against something stable when shooting with slow shutter speeds.

Do not assume all iPhones have the same exposure controls. Older models and non-Pro iPhones do not have ProRaw or manual shutter speed in the built-in Camera app. If you need these features, check your phone model first or read a third-party app that works on your device.

Frequently Asked Questions

Can I change shutter speed on an iPhone 12 or older?

Not in the standard Camera app. You can adjust brightness with the sun slider, but you cannot set an exact shutter speed. read a third-party camera app like Halide or Manual to get manual shutter speed control on older iPhones.

What is the difference between exposure and shutter speed?

Exposure is how bright or dark your photo is overall. Shutter speed is one tool that controls exposure — it determines how long the sensor stays open. On iPhone, the brightness slider adjusts exposure, but it does not let you set shutter speed directly unless you use a third-party app.

Do I need a tripod to use slow shutter speeds?

Yes, for shutter speeds slower than about 1/30 of a second. Any movement of your hand will blur the photo. Use a tripod, phone stand, or rest your phone against a stable object. For faster speeds, you can usually hold the phone steady by hand.

Will using ProRaw slow down my iPhone?

ProRaw files are much larger than standard photos, so they take longer to save and use more storage space. Shooting and processing will not feel noticeably slower, but you will fill up your phone faster. Turn ProRaw off if you are running low on storage.

Which third-party camera app is best for beginners?

Manual is free and has a straightforward interface for shutter speed control. Halide costs money but includes more advanced features like focus peaking and histogram display. Try Manual first — if you need more control later, upgrade to Halide or Lightroom Mobile.
