Thumbnails of Lightroom CC 2015.4 shaded in the timeline

When you work on a Lightroom Catalog locked up, when I rebooted my Mac and opened Lightroom thumbnails are all grayed out.  How can I get back them?

Please delete the catalog Previews.lrdata.

  • Choose Lightroom > catalog settings > General >Show
  • Open the folder and rename the Previews.lrdata.old to Previews.lrdata folder (it must have the same name as your catalogue)
  • Restart Lightroom

  • Creative cloud: lightroom cc 2015 is not in the list

    Creative cloud: lightroom cc 2015 is not in the list of the app to upgrade. I have Lightroom version 5 in win 7 32 bit.

    Since Lightroom 2015 CC (Lightroom 6) is a new product, it will not show as an update. Instead, press the button install next to Lightroom in the creative cloud Adpbe desktop application. If you do not see 'install' by Lightroom in the application manager, please first try to log out and return to: connect and disconnect from the creative cloud desktop application

  • Lightroom CC (2015) does not recognize the lenses since the last update

    I installed updates to Lightroom CC (2015), CC Bridge and Photoshop CC (2015) on 20 March. Since then, LR does not have lens ID in the exif data. It displays all the lenses as 'unknown '. This issue coincides with the last update and I confirmed that the lens information in the exif data. What is the reference for this?

    It will not be restored automatically. My understanding is that after upgrading to the next version, it will be necessary to filter the images concerned, select all, Ctrl / Cmd + S to write metadata (in order to keep all work performed since importation), then do file metadata reading to get the lenses update info.

  • Can I copy photos from Adobe Bridge CC on Adobe Lightroom CC 2015.

    I used Adobe Photoshop CC 2015 and I have pictures stored on a hard drive in three different places.

    1. on Adobe Bridge CC 2015 (DNG and JPEG Formats)

    2. on a folder full of photos (TIFF and JPEG Formats)

    3. on a ship (JPEG format) file

    The photographs on the completed folder and the folder of the ship are also all recorded on the folder Adobe Bridge CC.

    I want to start using Lightroom CC 2015, but I'm not sure if I should copy all the photos in Adobe Bridge CC on Lightroom CC 2015 and if so. the best way to go aboiut it.

    Hi LINGARBAY,

    Bridge CC is only a sort of explore to manage images, but for Lightroom, you need to import the images in the catalog and work on it.

    Please let me know if you need any other assistance.

  • Develop module is slow to load images in Lightroom CC 2015

    Whenever I look at a new image, it is slow to load in the develop module. Which means that when I click on a thumbnail, the image looks flat and not edited for 1-2 seconds until finally, it support. This occurs even after the generation of previews of standard sizes.

    The library module is always fast and has no problem with that.  This problem did not exist before the update of Lightroom CC 2015.

    Everyone has noticed this or a solution?

  • Lightroom CC (2015)

    Since the update to the latest version of Lightroom CC (2015) a few weeks ago I was able to start Lightroom. If I try to the desktop icon or the open command of the creative cloud it just won't do anything.

    I use a PC with Windows 10 - until the last update, everything was fine.

    I tried the signature on the "fix" identified on other forums - when I do that need me through the opening sequence of the product license or tried for 7 days then it just fails once again. I tried to remove the CC license of Lightroom. I tried the reinstalling.the software.

    My CC Photoshop works very well.

    Please help - incredibly frustrating!

  • How can I make keywords from Lightroom 2 to Lightroom CC 2015?

    I just installed Lightroom CC 2015.  How can I make all my keywords in Lightroom 2 and have them in my new version?

    Tom Bowie

    The key words are stored in the catalog.  Just move the catalog and your words keys will always be there

    OR

    If you mean that you can export a list of keywords to a new catalogue - Yes - Menu in the menu bar metadata > export keywords

  • Go Lightroom CC 2015.1 Standalone trial

    I'm nearing the end of my trial of Lightroom CC 2015.1, & I've already decided the stand-alone version would be better for my needs.  I downloaded the presets paid in my trial version & I would like to be able to use them in the standalone version, as well.

    My question is... How can I change?  Should I just buy the standalone version and enter the license number in the version that I already downloaded on my laptop?  Or will I have to download the standalone version from scratch once that I buy it?

    Thank you in advance for your help!  I appreciate it =)

    Help please:

    Just got my installed fiber, upstairs and downstairs, 50Mbits got all you leave to be able to start using Lightroom mobile correctly, but the uploads stuck after a while. In addition, the download performance download vs are much slower, even though I have the same bandwidth up and down.

    I tried:

    1.) first intelligent building previews and then sync

    support for market graphics switching 2.).

    3.) remove all of the mobile catalog and start again

    What doesn't help is to restart the machine/Lightroom as it again, but when you have a 20 thousand images you want to synchronize, who continually do it becomes a problem.

    I do not know what is the cause and does not seem to find any real help online. Help, please.

  • Import dialogue crashes when it's attached disk external HARD - Lightroom CC 2015.6

    Hello

    You are looking for assistance.

    Lightroom is suspended when you try to import photos via the import dialog.

    I installed the latest version of Lightroom CC (2015.6) for Mac, and I understand that the previous versions had a bug of import but that this has already been resolved in 2015.6.

    I was able to isolate the problem to my external HARD drive. I bought a WD disk Raid Duo lightning strike and loaded with photos.  When it is disconnected, there is no problem with the import. When connected, the importation is suspended.

    If Lightroom is trying to read all the pictures on the external HARD disk and gets overloaded? How can I solve this?

    The HARD disk is functional with the Finder and my other apps, just not Lightroom.

    I don't think I've had this problem in the latest version of LR.

    Phone support Adobe has solved my problem by changing the permissions on some files.  This solution is described in some of the other threads, I think.
