The new updates of Camera RAW and Lightroom promise to increase the detail of our photographs
There are new updates within the Adobe photographic universe: Camera RAW 11.2 and Lightroom 8.2. Thanks to the Sensei technology they have managed to increase the resolution of our photographs and therefore improve the detail of the RAW files coming from both Bayer-type sensors and Fuji’s more complicated X-Trans sensors.
From time to time the Creative Cloud surprises us with an update. It usually consists of small fixes and the updating of compatible files (the files of the Sony A6400 and the Olympus E-M1X can now be revealed ). Other times we find small treasures that may go unnoticed by most. This time is good news for all the happy owners of Fuji cameras.
The new function that we can find in both versions of Lightroomand in Adobe Camera RAW is called Details of the improvement , a very bad translation of Enhance Details (Why not call it Improvement of details ?). Before explaining it, let’s see how they tell us in Adobe :
Enhance Details uses an intricate neural network (CNN) with extensive training to optimize the maximum image quality. We formed a neural network for demonstrative raw images using problematic examples, and then we took advantage of the new machine learning frameworks integrated in the latest Mac OS and Win10 operating systems to run this network. The neural network has been trained with more than one billion examples. Each of these one billion examples contained one or more of the main problems listed above that give serious problems to standard demosaicing methods. We make two models: one for Bayer sensors and one for Fujifilm X-Trans sensors. As a result, the improved details will offer amazing results,
It’s a little complicated to understand. It can be explained in another way. Thanks to artificial intelligence (is not this term abused in photography: focus of the Sony A6400 , revealed from various programs …?) The interpretation of the raw information of the RAW file is much more precise in terms of resolution and color, regardless of the color pattern of the sensor filter that our camera has.
It seems that the problems in Adobe with Fuji’s .ORF files are finally over. At last we will be able to enjoy all the quality it has, far superior to that of many sensors with a Bayer pattern.
But bad weather good face, as my dear grandmother said. It seems that the problems in Adobe with Fuji’s .ORF files are finally over. At last we will be able to enjoy all the quality it has, far superior to that of many sensors with a Bayer pattern.
How does improvement details work?
As we can read in the Adobe blog , the explanation is very simple. All the photographs that we make with our digital cameras are in black and white. The pixels only see the luminosity, without any color. Only thanks to the RGB matrix that the photoreceptors have on top of and by a process called demosaicing .
Each pixel only records one color. And it lacks the information of the other two. What demosaicing does is generate the final color from that information. This is easy in large areas of color such as the sky or a wall. But it can be very complicated in small areas with details and textures.
If we work with a sensor that has a Bayer matrix, the work is much simpler, because the arrangement is completely logical and perfect, as if it were a three-color chessboard with a repetitive pattern. The subject is much more complex with an X-Trans sensor , with a much more random arrangement of colors.
