Under certain circumstances, the light from our surroundings impacts in some way the lenses of our iPhone’s cameras, resulting in small éclairs, usually green. Aware of this situation, Apple seems to have taken measures in the matter, at least that gives us food for thought on the last beta of iOS 15.
Even smarter processing
The amount of processing the iPhone goes through for each of the images we take is truly amazing. All of this happens in the Image Signal Processor, or ISP, which does this task in a specialized way. A task that is now improving because, to our knowledge, Apple has updated the ISP’s operating algorithms so that the system is now able to remove lens flare.
The discovery was made on Reddit, where a user claims that clearly saw the flashes before capturing the image, but after reviewing the final image, they were gone.
I noticed something that I have not seen reported elsewhere; while away from home I took this photo and thought it was ruined / needed to be changed later due to stray light (as I have done on several occasions on previous photos with the iPhone 12 Pro because it is so prone to lens flare). The lens). However, I got home and noticed that the lens flare had disappeared automatically on the original photo, although it was obvious that it was still there in the live photo, which means the automatic post-processing has become smart enough to eliminate the goal. to burst.
For a development version, however, we don’t know if this is a feature that will reach the final version. Apple could very well test or decide that the system needs to improve further. What we do know is that now we are going to pay more attention to these possible flashes to find out how the post-processing of the system improves our images.
It is clear that much of the magic of the photographs we take with our iPhone occurs in the further processing of the information collected by the sensors. This is a physical issue, the sensors have several limitations due to their size that only the ISP can correct. An ISP who, in iOS 15, will be even better and more capable with our photographs.
