Adobe Enhance Details Increases RAW Photo Resolution By Up to 30%



Adobe announced a new feature for Lightroom and Camera Raw called Enhance Details. Take advantage of the power of artificial intelligence to produce more detail and fewer problems in RAW photos.

More specifically, the function uses machine learning and computational photography to rethink how RAW photos are faded (in which the data captured through the array of a digital camera pixels red, green and blue are rebuilt in a color photo).

Adobe states that the Details enhance the resolution of Bayer and X-Trans sensor cameras by up to 30%, improving both the rendering of details and the rendering of details and the reproduction of refined colors.

Here is a comparison that shows a 200% zoom of a photo captured by a Fuji X-Trans sensor: the greatest detail can be seen in the street lights and in the windows of the skyscrapers:

[19659003] Here's a second example:

When you capture a photo through a Bayer or X-Trans filter, the cameras record a single red, green, or blue light intensity value on each pixel. When calculating that color pixels should actually be in a photo, the RAW processors must guess the most probable value based on adjacent values ​​(something called interpolating ).

And while common The "demosaicization" strategies work well in some situations – uniform gradients and constant color areas, for example – can counteract and produce suboptimal results in others (eg plots, fine details, patterns, sharp edges , etc.).

A photo with small-scale details that benefit from Improved Details.

There are advanced demosaicing algorithms that can handle these photo areas well, but performing them would require a significant amount of time even on powerful and expensive computers. Therefore, RAW processors are generally satisfied with a non-optimal result that is completed in a reasonable amount of time.

But thanks to the power of the AI, it is now changing. Adobe is putting its Sensei AI engine to work, bringing "deep learning" to the challenge of demosaicing difficult areas in RAW photos.

The company has trained its artificial intelligence on over a billion examples of problem areas – things like small-scale details, false colors and lightning (blurring at the edges of photos). The result of this workout is the new Enhancement Details feature, which produces considerably more detail than before with less artifacts.
