Lightroom/Camera Raw: Enhance Details

I have been trying to explore "Enhance Details". Here is the status so far:

1. "Enhance Details" works in Camera Raw. At least it produces a .dng file, in about 45 Seconds. I could notice some subtle differences in the areas containing details, such as patterns, edges, glass reflections...I have to look at the results on larger monitor and explore with some more images. Original .NEF was about 20 MB, Enhanced DNG was about 80 MB

2. In Lightroom Classic CC, on the same image, it does not work properly. It takes a very long to create the .dng file, and the .dng file is "Black", about 24MB.

3. In Light room CC, it does not work at all.When I tried another image, captured on iPhone 7, Lightroom CC mobile Camera. .dng file, there is an error message: "Loading Photo failed". Could not open the photo, Restart Lightroom

Questions:
1. Since Lightroom Classic CC uses same Camera Raw, the same image should have worked in Lightroom Classic CC and the Camera Raw

2. Is the dng file, created by iPhone 7 supported for "Enhance Details" function?

3. Anything else that I am missing?

I tried the Same NEF file with LIghtroom CC. It also produces "Black DNG". Further information, GPU is enabled in ACR, Lightroom Classic CC, and Lightroom CC.

My little grain of salt:

1) I don't really understand why the new file is way larger. Has information been created or just better extracted from the RAW file. If the file size (pixel wise) and bit depth is the same, I don't really get why the file must be that bigger...

2) I guess you just have to wait (longer) for the file to be created. The black image is just an empty file wiating for the actual data.
But as the engine behind all those are the same, I don't really understand why it takes that long in classic. Classic has always been "behind" speedwise, maybe ther's a lack of optimization.

3) Never tried LR CC... However, I don't know if the iPhone's lens is sharp enough compared to the pixel pitch. If its confusion circle is wider than the bayer pattern, there is no need for another demosaicing method.

1: The new file is larger for two reasons. First of all, it contains both the 'unenhanced' data as well as the 'enhanced' version. That is for compatibility reasons. And secondly, the enhanced data are demosaiced. That means that they contain all three colors per pixel. RAW files only contain one color per pixel.

contrary to what some so called experts are saying on youtube, I clearly see improvements through the enhanced mode. However, it appears to be useful only for images with a lot of fine detail. such as bird-feathers, leaves, landscape with trees etc etc.

1. I am still not able to use "Emhance Details" in Lightroom Classic CC or Lightroom CC Desktop. It works in Camera Raw. My setup is Windows 10, Latest update including 1809. AMD R9 M200X series GPU. Any suggestions?

2. Where in the workflow should Enhance Details be used? Before any other edits? After all the edits?. I find that adjustments in "Transform" are removed after applying "enhance Details"

Enhance Details creates a new file, so it doesn’t matter if you do that before or after applying edits to the original file. Edits are not destructive and do not change the original pixels.

Johan, thanks for the info. I personally wonder:: should one apply edits before or afer enhancement. to me it would make more sense, at least to sharpen a picture AFTER enhancement

By the way, I have found that - in difficult lighting conditions - the enhance-mode will visibly improve resolution and add light sources where there was pitch-darkness before. Obviously you won't see this unless you own a good monitor

"Enhanced details" was not working for me, with Lightroom Classic CC till yesterday, as mentioned in my original post in this thread. It started working today. The only thing different now is, I have updated Camera Raw to the latest version. I cannot say for sure whether this is the reason, but I thought I should let the "Family" know about this. Maybe, the guys at Adobe get some clue!

YES! It started working for me, too. At least, it does not crash. It is subtle if even visible with the image I tried it on just now. But it did not crash! Progress! Now if only I could run any of the video editing software (I have a modest laptop for a computer).
