Deep Fusion emerged to greatly enhance the iPhone's photo capturing capabilities. However, not everyone grasps the full scope of what Deep Fusion is and how it functions, including how to toggle it on or off on their phones. Mytour is here to provide you with an in-depth understanding of this feature in the following article!

What is Deep Fusion?
Deep Fusion is an intelligent image processing technology under the support of the Neural Engine. Apple equipped this feature in the iOS 13 version released in 2019. Deep Fusion utilizes artificial intelligence to deliver sharper images, significantly improving limitations in photography such as noise reduction, capturing in low light conditions, and more.

Besides, this feature on the phone will activate automatically without any guidance or notification. However, in certain scenarios like capturing wide-angle shots or continuous shots, it might deactivate automatically.
How does Deep Fusion operate?
After understanding what Deep Fusion is, let's explore how this feature operates. When you capture photos with this feature, multiple images will be continuously taken and combined. The iPhone camera will capture 9 images, including 4 short-exposure, 4 secondary, and 1 long-exposure photo.
The Neural Engine has the function of analyzing and combining to select the most beautiful photo. The entire process takes only about 1 second. Simultaneously, Deep Fusion traverses the points in the image to select and optimize, reducing noise and enhancing contrast. The end result produces a photo with higher sharpness and detail.
This is considered a significant advancement in image processing technology on the iPhone, elevating this smartphone line to new heights in photography and meeting user demands.
How to determine if Deep Fusion is active?
Deep Fusion operates silently, providing no notifications for users to be aware of its functioning. In certain scenarios, it activates, such as capturing low-light or telephoto lens photos. If you use an ultra-wide lens, it remains inactive, replaced by the Smart HDR mode.
To check if Deep Fusion is active, examine the quality of photos taken. After opening the camera app, try capturing a photo in low or moderate light conditions. If the recently captured photo exhibits higher sharpness and detail than usual, it indicates the feature is active. However, this method is sensitive and challenging to guarantee accuracy.
Additionally, you can check notifications on the screen. If the display shows 'Processing' or 'Smart HDR' within seconds after taking a photo, Deep Fusion may have been activated.
Key Feature of Deep Fusion
After a long time trailing behind competitors like Samsung and Huawei, Deep Fusion on the iPhone can now change the game. This feature is applied to produce photos with outstanding sharpness even in challenging lighting conditions. Applying artificial intelligence improves the hardware limitations of the iPhone camera.
With this feature, images captured by the iPhone camera display true colors and excellent resolution. In fast-moving situations, this feature ensures sharpness in photos. Simultaneously, pre and post-processing of images create a final picture with high accuracy.

The advanced Deep Fusion technology finds its home in various iPhone models, including iPhone 11, iPhone 11 Pro, iPhone 12, iPhone 13, and more. Undoubtedly, this feature has elevated the photography experience, delivering professional-quality photos to users.
Guide to Enable/Disable Deep Fusion Feature on iPhone
The Deep Fusion feature activates automatically when you use the telephoto lens in the camera app. However, it deactivates when using the wide-angle lens or engaging in continuous photo shooting. To activate Deep Fusion on the iPhone, you need to turn off the 'Look Around Frame' in the settings.
For the iPhone 11 Series, you can refer to the steps below to enable/disable:Step 1: Open 'Settings' (gear icon) on your iPhone

Step 2: Choose 'Camera'
Step 3: Turn off the 'Look Around Frame' option
For iPhone 12 and later models, Deep Fusion is integrated into the ProRAW feature on the camera. Therefore, you only need to enable ProRAW using the following steps:Step 1: Open 'Settings' (gear icon) on your iPhone and select 'Camera'.

Step 2: In the 'Apple ProRAW' section, slide this bar to the right to enable it; now the bar turns green.
Through this article, you've likely learned what Deep Fusion is and gained a better understanding of how this feature operates. Hopefully, this knowledge will assist you in using your iPhone camera more effectively, producing sharper photos. Stay tuned for more insightful technology articles from Mytour!
