Lightroom Mobile: grid view and slideshow with wrong colors for smart previews

Hi,

  I found a specific condition (bug?) making LR Mob presenting incorrect previews in grid view and slideshow.

With “incorrect” I mean with the wrong color profile (non the currently assigned one).

This is how I get it:

1) In LR Classic I select a photo (original raw) and I edit its camera profile assigning a new one. For better test I use an image with strong colors so it is easy to see the effect of the profile change even if the image is presented in a small dimension.

2) Still in LT Classic I build a smart preview as I know that LRClassic can only synchronize such kind of images (not the original one).

3) I disconnect the disc with the original file. LRClassic still shows me the photo as it shows the smart preview. The colors are the right one, those of the new assigned camera profile.

4) I add the image to a synchronized collection. LR Classic start synchronization. I am sure It sends  the smart preview because it cannot access the original (it is on the disconnected disc).

My guess is that it send a smart preview with colors coherent with the assigned profile  as I see them properly on the screen during synchronization.

So far, it’s all ok.

Now the problem:

5) I open LR Mob and wait for the image to arrive in the collection. When it arrives, it appears in the grid view with WRONG colors. Probably they are those given by the default profile. In any case, the are not the expected color related to the assigned profile.

6) I tap on the photo to edit it. LR Mod opens it initially still showing the same wrong colors until the hourglass stops turning.  When the full image (smart preview) has been downloaded it suddenly get the right color (those of the new profile). So it knows how to show them (the profile assigned to the image exists locally and LR Mob use it during editing).

7) If I get out of edit and back to the grid view, LR mob again forgets the right colors and revert to wrong ones.

To get the right colors in the grid view, the only way I found is to edit the image slightly in LR Mob itself before exiting the edit session. This way, it  wakes up (rebuild) the thumbnail view and finally it shows the right colors in the grid view too.

Of course that is very annoying .

Moreover this bug affects also the slides shows. When the image with special assigned profile is shown in the slide show, for a few seconds it appears with the wrong colors, and after 2-3 second it changes again the colors , but not to the right way. It gets a third colors profile from who knows where .

In other word, slides shows are not usable with images with edited camera profile and coming from LR Classic (=smart previews).

Any idea about a way to force all of images of a collection to update their local previews to match the assigned profiles as it does, one by one, when LRMob opens an it for edit?

Thank you in advance for any suggestion

Mauro

In the meanwhile, I found that the same problem appears  in Lightroom web too.

It seems to be related to the thumbnails (local previews) for grid, slideshow and other view modes when they represent images having a  just imported camera or creative profile assigned to them.

These are the steps to see the odd behavior:

1: LR Classic. Create a new profile and assign it to a photo

2: add that photo to a synchronized collection

3: open LR CC and import the new profile. Now you can see the photo in the right way.

4: open LR Web. You see the photo because it is synchronized, but the thumnail in the grip is not aware and appears with default (wrong/not expected)colors.

5: still in LR web, start editing the photo. It immediatelly changes to the righ color, because the profile is there (it is synchronized by LRCC). If you do no make any change, you do not have "save and exit" option. So you can get back to grid with the arroy but the color are back to wrong.

6: still in LR web, enter again in edit and change anything. This time you have the "save and exit" enabled and can press it to get back to the grid and finally you can see the right colors.

Hope this can  be useful to spot the problem and find a solution (eg.: a function like "build previews" in LR Classic that can rebuild the local previews? A check that detect a new profile has been just synchronized and rebuild local previews of images affected?...).

Hi Mauro,

Could you please share a screen recording of the steps your are trying on Lr Classic? It will help us in debugging and understanding the issue better.

As requested, I wrote here a full guide to the odd behavior I detected, with screenshots.

Acronysm:

LR = Lightroom CC

LRC =Lightroom Classic

LRW=Lightroom Web

LRM=Lightroom Mobile

All of them updated at the latest available version today.

Screenshot folder: https://www.dropbox.com/sh/r98kq1hfeakvqab/AACklGfQ68KWImc8bap_cRSQa?dl=0

To setup the starting point, I prepared in LRC a synchronized collection with 3 images. Two of them only smart preview and the third original with smart preview.

I made so just in case problems could arise only for synchronized smart previews, but It will not.

You can see all the applications perfectly synchronized in these screenshots: 1a(LRC), 1b(LR), 1c (LRW),1d(LRM)

You can follow the path through the screenshots:

2ab: screenshots show that LR and LRW see no used defined profiles. The cloud is clean.

3 LRC: now I use LRC to assign a custom profile: TEST 1. I made such profile via Photoshop, by simply inverting the blue curve, in order to clearly see when it is applied.

4 LRC: now I synchronize the edit to the other images in the collection. All three become bluish. I wait the cloud sync goes on…

5 LRC: cloud sync is completed.

6 LR: LR properly shows the three grid previews with bluish colors, even if the Test1 profile is NOT available. I guess it takes it from the local disk.

7 and 8: to share and broadcast the TEST1 profile, I import it by using LR.

9: Now LRW  show the previews are correct.

10: ..and TEST1 profile is available in LRWeb

So far, so good: a change in profile has been sent all around as expected (even if we have not yet checked LRM).

Now I change again the profile of the three images back to Adobe Standard, this time by using LR (not LRC).

11 LRC, for some strange reason, reacts by syncing properly only two images. The image that I left in develope mode is still with TEST1 profile. I have no way to force LRC checking the values in the cloud. LRC thinks synchronization is over and fine, but instead...

12: ...LR shows that in cloud the same image has Adobe Standard profile, not TEST1 as LRC shows. (BUG?)

Now , lets have a look at LRM.

13: LRM still shows all three grid previews with the wrong bluish look belonging to test1 profile), but…

14 LRM:...if I enter in modify mode, LRM wakes up and change colors to the currently assigned profile (Adobe Standard).

15 LRM: When I get back to grid view without any modifcations, the grid still shows the wrong colors, even if it knows the color shoud be different as it showed them properly in editing! (BUG!)

16a and 16b: I enter again in modify mode and change slightly one parameter, in order to make LRM rebuild the grid preview (my workaround for single image problem).

17: now the modified image has a grid preview with expected colors (Adobe standard), but the other 2 remain with wrong colors, not matching their assigned profiles.

BTW, if I logout and login again the app, all remain unchanged.

Now imagine if I would have a hundred photos with grid previews mismatching with their assigned profiles. Making a small change to all of them, one by one, is not a viable workaround.

The only fast way I found to bring LRM back to a coherent grid previews state, is by unstalling the app and installing it again (my current workaround when many images have grid previews are out of sync). After a fresh app install:

18: the grid previews are ok

19a,b: the TEST1 profile is synchronized and available in the user defined group ("profili utente" in italian at the end of the list)

Now we can meet another not properly synchronized event: profile deletion .

20a,b,c: In LR I delete the TEST1 profile.

I would expect that  action should affect both LRW and LRM.

21: LRW is affected indeed : TEST1 profile and user defined profiles both are gone.

22,23: Surprisingly LRM still have TEST1 among user defined profiles (BUG?).

24: Only by unstalling and reinstalling the app I can get rid of it.

I made my move.

Now is your turn.

I added TEST1.xmp to the same shared folder of the screenshots.

The link is in my last message in this thread.

I made it by Photoshop/ACR by simply inverting the blue curve (from "/" to "\").

Hi Mauro,

We tried reproducing the issue at our end and observed that it's taking longer than expected to update the thumbnails in LrM. Could you please confirm that you are also seeing some kind of delay for the thumbnails to update or it never updates at all?

We are woking on the issue and would get back to you if we have any update on it and thanks for bringing this issue into our notice.

I made other tests, but the result is still the same: changes to profile assigned to an image in LRClassic or LRCC is not always applied to the grid previews, no matter how long I wait.

In this exact moment I have a grid view on the mobile screen for a collection of three images with my custom profile (it is available in LRMob among the others):

- two of them has wrong colors, not related to any assigned profile (I guess it is a fallback to default Adobe profile)

- the last one has wrong colors, those related to the previouly assigned profile. I don't now if the cause is that such image is the one representing the collection in the collection list view.

In LR Web I see wrong colors too, but all three images have the same look: colors of Adobe Standard (probably due to fall back)

On LRClassic, LRCC all the images appear in the expected way.

LR Mobile is open since 15 minutes ago. No changes. Usually, I get changes due to sync on less than 20-30 seconds, when sync happens.

LR Web is open too since 15 min: no update, even if I refresh the page.

I uninstalled and reinstalled LRMob. Now I see the grid preview in LRMob like in LRWeb: all three images with wrong colors, but wrong in the same way (probably the default color).

The funny thing is that, when I edit each image in LRMob, its colors changes to the exptected one! But when I get back to grid with no changes in edit, they are still wrong, no matter how long I wait.

In conclusion, the problem is consistently there, not matter what I do to force sinchronization, no matter how long I wait.

I hope you will detect the cause because it weakens the synchronization mechanism of profiles, that is very useful since when  creative profiles have be added to LR.

I reported what appears to be the same color management bug at the below Photoshop Family post. Adobe Engineering is looking into a fix, but no solution yet.

Hi Todd, I doubt it is the same bug, even if it shows up with the same effect.

The reasons for my doubts are:

- the reported bug in the other thread seems related to mobile only, not also to LRWeb like in my case.

- it seems related to a color space management in mobile phones and how they play with color enhancements, rather than a profile sinchro issue like in my case

But they have a common point: entering in edit mode changes color compared to preview in grid. In my case, the change makes colors better, in the other one it makes colors worst. Maybe this grid/edit mismatch could have a common cause.

Let see if Adobe tech people can catch both bugs and fix them with one shot.

The reasons for my doubts are:

I mention that it also affects the LR Web app. It appears to be due to the fact I'm using a wide gamut monitor and the Web app doesn't use the display profile and instead assumes it is sRGB.

When reviewing synced albums using LR Mobile for Web with color managed Firefox (v66.0.3) browser there is no delay in rendering, but the image appears slightly under-saturated. However, when clicking on ‘Edit this Photo’ the image appears over-saturated on my wide gamut monitor. This appears to be due to the monitor’s display profile being bypassed. Chrome (73.0.3682) browser does not exhibit the issue.

If it happens in LR Web too, you could be right. Both behaviors show some problems in the color chain and the synchronization of the involved components.
I am aware that mobile devices present a variety of hardware and software environment difficult to manage evenly, but I hope that Adobe fix it in the next release of LR .

EDIT 14th Aug 2019

The update installed today (LRCC 2.4; LRC 11.4; LRMob 4.4) has not fixed the issue described in this thread.

Exact same issue here as Mauro on Apple devices. Previews never update to correct colors on mobile devices, only temporarily by loading them under the edit tab. Shared albums on any browser and any platform display erroneous colors as well. As a result I can’t use the shared album function for sending photos to newly weds for selection. Could you please kindly fix the issue as a priority as it impacts business flow? Thanks

Adobe has not provided answers or fixes to this issue. I personally haven't found any solutions either.

 

Previews with correct colors still only update if adjustments are made in the mobile apps.

 

Very annoying bug!

I'm having the same issue.  I was amazed to see that it was reported a year ago and adobe hasn't acknowledged or fixed it.  As I use a camera profile for inverting film negatives, this means that lightroom mobile is totally non-functional for me.  It's just not practical to open every photo on the web, make a meaningless change and then save it just so that it reads the profile correctly and updates the preview.

 

Please provide a way to force updates of previews saved to web or some other solution.
