Beta testing of Apple's mobile operating system has never been so interesting. After eight seeds from iOS 13.0, Apple unexpectedly released the first beta for iOS 13.1, a whopping 23 days before iOS 13.0 made its public debut. Since 13.1, however, we no longer had any betas to delve into. That's until now, when Apple released the first developer beta for iOS 13.2 today, Wednesday, Oct. 2.
This beta release is the first since iOS 13.1 Beta 4, which expired on September 18th. With iOS 13.1, 22 new features for compatible iPhones have been introduced, which complemented the more than 200 new features of iOS 1
We do not yet know everything that brings 13.2 to the table, but we know the following: Deep Fusion is here. Deep Fusion is Apple's latest update for the iPhone 11, 11 Pro, and 11 Pro Max cameras. Unlike night mode, the technology works in the background, so you might not even notice it's there at first. However, you should notice the changes in your photos as Apple promises images with much deeper levels of detail.
The Verge, who was able to access the feature early on, explains in detail what's really going on:
- When you press the shutter button, the camera has already taken four pictures with a short shutter speed to stop the movement freeze in the recording and in four standard pictures. Pressing the shutter button will take a longer exposed shot to capture details.
- These three regular and long-exposure images are merged into Apple's "Synthetic Long" recording. This is a significant difference to Smart HDR.
- Deep Fusion captures the shortest picture with the most detail and merges it with synthetic long exposure. Unlike Smart HDR, Deep Fusion does not merge these two frames – though the Synthetic Long already consists of four previously merged frames. All frames are also processed differently from Smart HDR for noise, which is better for Deep Fusion.
- The images are processed pixel by pixel in four detailed steps, each tailored to increasing levels of detail – the sky and walls are in the lowest band, while skin, hair, fabrics, etc. lie on the highest level. This produces a series of weights for blending the two images – taking details of one and tone, color and luminance from the other.
- The final image is created.
Apart from Deep Fusion, we can only speculate on what's new with 13.2. Once we have studied the software, we can report any change we've seen since iOS 13.1.2. Apple's release notes, which may be helpful in learning more about the beta software, are quite short this time:
