Enhanced Detail is a new, optional
AI-based tool that improves perceived detail rendering for most raw file formats, not just XTrans raw.
Enhanced Details is not possible for images that were demosaicked outside of LR (JPEG, TIFF, etc).
It is not an image sharpening tool.
It is used during the demosaicking computations (link
). It can not make an inherently blurry image sharper. It was designed to "produce crisp detail, improved color rendering, more accurate renditions of edges, and fewer artifacts
Besides LR CC, it is also available in Adobe Camera Raw (Photoshop) 11.2.
Enhanced Details does take more CPU time so for some it may be practical only for keepers. Enhanced Details requires OS X High Sierra (version 10.13), Windows 10 October 2018 update (version 1809) or later.
For OS X, some video graphics cards are not supported.
I suspect there will be a wide variation in anecdotal reports about Enhanced Details. For some it will be extremely slow. Others will claim it does nothing whatsoever. And some will report significant improvements. I suspect the main advantages will be found when making large prints or smaller prints from cropped images.
