P: Poor photo in the library and develop module - smart previews

[FeedbackCommunityMember]

I have a problem with version 10.0,
the photo is of poor quality in the library and in the develop module. I use smart previews (the disk with the original photos is disconnected).
smart previews in version 10.0 have poorer quality than in version 9.4
When I install the older version (9.4), the same photo with the same preset is of better quality (also smart previews).

It looks like there is a higher grain in the photo
Here are photos exported from smart previews.

Tested on: Mac pro 2013 (6core, 16gb ram, D500)

Macbook Pro 2014 2,7 ghz 4 core, 16gb ram

10.0:

( I think there ist something wrong on my LR

Which is why I asked if you'd also examine Adobe Camera Raw....

[martinh25301180]

No changes after deleting the cache.

Can we restart please.

1. The picture in library looks horrible (Fit Mode)

2. Switching to Develop the pic is also horrible, but only for one second then it will be better (Fit Mode)

3. Switching back to library the pic ist horrible (Fit Mode)

4. Zoom in (Library) and the pic will be better after 5 to 10 seconds

5. Back to fit mode 

After this the pic will be alright in library or develop.

Changing the grain and the game starts again

I don't know what ACR is. I only know the camera raw module in LR ans PS. I cannot find an application with this name in my cloud abo

[TheDigitalDog]

Sorry: ACR is Adobe Camera Raw. Please also test in that Photoshop plugin and let us know what you see.

[martinh25301180]

Opening your DNG:

ACR shows me a awfully monochrome picture for one second, then it will be ok.

[TheDigitalDog]

ACR shows me a awfully monochrome picture for one second, then it will be ok.

And that's what I see too. But on Mac. 

I wonder if you might try creating a new catalog. Import one or a few of these raws, having that catalog rebuild new previews for both Develop and the other modules. Any improvement or the same issue? 

[martinh25301180]

I've tested a new catalog. The picture (dng) in library is monochrome (not in color like the other) but also bad. 

[TheDigitalDog]

The picture (dng) in library is monochrome (not in color like the other) but also bad. 

Try one more thing; import the original raw, not the DNG into this new catalog. 

[martinh25301180]

Done. If i use grain on this raw, it's the same like in the other catalog. 

[TheDigitalDog]

but it seems the problem with the color/bnw is solved here

Solved how? Sorry I'm not sure what's now going on although I am happy to hear something is solved. 

[martinh25301180]

Sorry, nothing is solved. My failure. It's all the same, except that LR opens the DNG monochrome and not colored like the other catalog

[TheDigitalDog]

So it is OK in Camera Raw after a second. If you apply a tiny edit in ACR, click ”Done” then examine the same raw in LR AFTER using the update metadata from disk (to update that new edit from ACR), how does it look; match ACR?

[martinh25301180]

Sorry, i don't know what you mean. If i save a raw in PS i have a tiff.

[TheDigitalDog]

Sorry, i don't know what you mean. If i save a raw in PS i have a tiff.

You could have a TIFF if you click Open, I don't want that, I want you to SAVE the edits from ACR using "Done" then examine the raw in LR after you ask it to update the metadata.

They all look nearly identical on my browser. 

The only accurate way to view this image data is in Develop, at 1:1 or greater. All other modules use a different preview architecture and zooming out is always less accurate due to subsampling. But again, all three posted images look the same here. 

[kimballisms]

I thought the same until I zoomed in with my browser.  Take a look at the bride's skin.  It's significantly more textured/grainy in the 10.0 export, just as the OP describes.  Once you see it you can spot it everywhere in the image.

Also this goes beyond mere viewing in a LR module.  These are exports from the smart preview that show significant differences between 9.4 and 10.0.  That is reasonable cause for concern.

[TheDigitalDog]

I don't see any zoomed in option.

This could be a similar issue discussed here:

https://feedback.photoshop.com/conversations/lightroom-classic/horrible-noise-in-library-module/5f91...

Like there, this OP should provide a DNG with all the edits and upload for others to examine. When I did so, I was able to generate previews correctly.

I zoom in on a webpage in Safari with a 2-finger gesture on my touchpad.

if you don’t have a touchpad you can use Command-+ or any of the other options mentioned here:

[TheDigitalDog]

I'm on Safari, can zoom in from the View menu, still see no difference. But what the OP needs to do is either upload higher resolution screen captures (or links to the original) or ideally, show us each module at 1:1 otherwise no one should expect a match. 

[kimballisms]

Remember these aren't screenshots of a LR module, these are exports from LR using the smart preview.  Yes, they should match.

The differences are readily apparent from the images provided.  Let's see if this forum will show an animated GIF:

[kimballisms]

But I agree OP should see if he can share the original smart preview.

I have the same problem.
In the library and in the develop module, the photo is terrible (as if too much grain).
I have a disconnected HDD disk (there are original photos on the disk).

What do you think? original smart previews? I do not understand. The problem is also solved here:

[kimballisms]

While the originals are still disconnected you can export your example image as DNG in 9.4 and 10.0.

I wouldn't say that other thread solved anything.  It's a mess of bickering with no clear resolution.
