What is HDR on iPhone? HDR stands for High Dynamic Range, and it’s a camera feature that allows your iPhone to capture better photos with improved colors, contrast, and details. But what does HDR mean, and how does it work on your iPhone? In this article, we’ll explain everything you need to know about HDR on iPhone, including its benefits, how to enable it, and some useful tips and tricks to get the most out of it.

Understanding HDR on iPhone

What is HDR?

HDR is a photography technique that combines multiple images taken at different exposures to create a single photo with improved brightness, contrast, and color accuracy. By merging several shots into one, HDR can capture a wider range of tones and details that would be impossible to capture with a single exposure. The result is a more vibrant and realistic image that looks closer to what the human eye can see.

How does HDR work on iPhone?

On iPhone, HDR works by taking three photos in quick succession: one normal, one underexposed, and one overexposed. The phone then combines these images into a single photo that has the best elements of each exposure. The HDR process is automatic on iPhone and happens in the background, so you don’t need to do anything special to enable it.

What are the benefits of using HDR on iPhone?

The main benefit of using HDR on iPhone is that it can help you capture better photos in challenging lighting conditions. For example, if you’re taking a photo of a bright sky and a dark foreground, HDR can balance the exposure and capture both elements with more accuracy. HDR can also improve the quality of your photos in low-light situations, by reducing noise and increasing detail.

When should you use HDR on iPhone?

While HDR can be useful in many situations, there are some scenarios where it works best. For example, if you’re taking a landscape photo with a bright sky and a dark foreground, HDR can help you capture the details of both. Similarly, if you’re taking a photo of a person in a backlit environment, HDR can balance the exposure and prevent the subject from appearing too dark. In general, HDR is most effective when there is a wide range of contrast in the scene.

How to enable HDR on iPhone?

To enable HDR on iPhone, follow these steps:

  1. Open the Camera app on your iPhone.
  2. Tap on the HDR button at the top of the screen.
  3. Choose “Auto HDR” or “On” depending on your preference.
  4. Take a photo as you normally would.

Can you edit HDR photos on iPhone?

Yes, you can edit HDR photos on iPhone using the built-in Photos app or any third-party photo editing app. HDR photos are saved as regular JPEG files, so you can adjust them just like any other photo. Keep in mind that HDR photos may require less editing than regular photos, as they already have a more balanced exposure and color.


What is the difference between Auto HDR and On mode?

Auto HDR mode on iPhone automatically detects when HDR is needed and turns it on or off accordingly. On mode keeps HDR on all the time, which can be useful if you want more control over the exposure and color of your photos.

Does HDR use more storage space on iPhone?

Yes, HDR photos are larger in size than regular photos, as they contain more data and detail. However, the difference in size is usually not significant, and you can always save space by deleting unnecessary photos or using cloud storage.

Can HDR be used for videos on iPhone?

No, HDR is only available for photos on iPhone, not for videos. However, some newer iPhone models support HDR video recording, which can capture more detail and color than regular video.

Do all iPhone models support HDR?

No, not all iPhone models support HDR. HDR was first introduced on iPhone 4, and it has been available on most newer models since then. To check if your iPhone supports HDR, go to the Camera app and look for the HDR button at the top of the screen.

Can you turn off HDR on iPhone?

Yes, you can turn off HDR on iPhone by tapping on the HDR button and choosing “Off”. Keep in mind that turning off HDR may result in photos with less detail and color accuracy, especially in challenging lighting conditions.

Does HDR work with the front camera on iPhone?

Yes, HDR works with both the front and back cameras on iPhone, so you can use it for selfies and video calls as well.

Can you use HDR with third-party camera apps on iPhone?

Yes, some third-party camera apps support HDR on iPhone, but the quality and performance may vary. It’s always best to test the app and read reviews before using it.

What is Smart HDR on iPhone?

Smart HDR is a newer version of HDR that was introduced on iPhone XS and later models. It uses advanced algorithms and machine learning to capture even more detail and color accuracy than traditional HDR. Smart HDR is enabled by default on these models and cannot be turned off.

Pros of Using HDR on iPhone

Using HDR on iPhone can have several benefits, including:

  • Better color accuracy and contrast
  • Improved detail and sharpness
  • More balanced exposure in challenging lighting conditions
  • Less noise and grain in low-light situations

Tips for Using HDR on iPhone

If you want to get the most out of HDR on your iPhone, here are some tips to keep in mind:

  • Use a tripod or stabilize your phone to prevent blurry photos
  • Experiment with different HDR modes (Auto or On) to see which one works best for your needs
  • Use HDR sparingly and only when it’s necessary, as it can make some photos look unnatural or overprocessed
  • Combine HDR with other camera features, such as Night mode or Portrait mode, for even better results


HDR on iPhone is a powerful tool that can help you capture better photos with improved colors, contrast, and detail. By using multiple exposures and advanced algorithms, HDR can balance the exposure in challenging lighting conditions and capture scenes with a wider range of tones. Whether you’re taking a landscape photo or a portrait, HDR can make a big difference in the quality and impact of your photos. Just remember to use it wisely and experiment with different modes and settings to get the best results.
