Adobe has announced a new feature for Lightroom and Camera Raw called Enhance Details. It uses the power of artificial intelligence to produce more detail and fewer problems with RAW photos.
More specifically, the machine learning and computational photography function is used to rethink how RAW photos are demacaryzed (in which data captured with the red, green and blue pixels of a digital camera are reconstructed into a color photograph).
Adobe claims that Enhance Details increases the resolution of both Bayer and X-Trans sensor cameras by up to 30%, improving both the fine detail and the reproduction of fine colors.
This is a comparison that shows a 200% zoom of a photo taken with a Fuji X-Trans sensor – the increased detail can be seen in street lighting and skyscraper windows:
Here is a second example:
When you take a photo using a Bayer or X-Trans filter, cameras at each pixel record a single red, green or blue light intensity value. When calculating which color pixels should really in a photo, RAW processors have to estimate the most likely value based on the neighboring values (called something) interpolate).
And while common strategies for "demosaging" work well in some situations – such as smooth gradients and constant color patches – they can struggle and produce less optimal results in others (eg textures, fine details, patterns, sharp edges, etc.).).
There are advanced demosaicing algorithms that can handle these parts of photos well, but their execution would take a considerable amount of time, even on powerful and expensive computers. Therefore, RAW processors generally take pleasure with a less than optimal result that is completed within a reasonable time.
But thanks to the power of AI, that is now changing. Adobe puts its Sensei AI engine to work, which means deep learning & # 39; the challenge is to demosify difficult areas in RAW photo & # 39; s.
The company has trained its AI on more than a billion examples of problem areas – such as small-scale details, false colors and zippers (blur on the edges of photos). The result of this training is the new Enhance Details function, which produces noticeably more details than before with fewer artefacts.
To begin applying Enhanced Details to your RAW photos, you need to upgrade your Lightroom CC, Lightroom Classic CC and Camera RAW to the latest versions released today.
