The biggest benefit of Smart Previews is that you can edit your files in the Develop module.

Yes! That \u201cLightroom Previews. lrdata\u201d folder (looks like a file on Mac) can be deleted without losing any of your photos or any of the editing work you have done in Lightroom Classic.<\/p>\n<p>Additionally, can I delete <strong>Lightroom<\/strong> catalog <strong>smart<\/strong> previews? More Detail: In theory you could simply delete the Smart <strong>Previews<\/strong> file from the folder where your Lightroom catalog is stored. However, because you are able to work offline in the Develop module with Smart Previews, there is some risk that you could lose changes you&#8217;ve applied to photos based on Smart Previews.<\/p>\n<ol>\n<li>Update to the most recent version of Lightroom.  <\/li>\n<li>Exceed minimum system requirements.  <\/li>\n<li>Run Lightroom on machines with 12 GB of RAM or more.  <\/li>\n<li>Use a fast hard drive.  <\/li>\n<li>Make sure that you have a large enough hard drive and enough free space.  <\/li>\n<li>Update the graphics driver.<\/li>\n<\/ol>\n<\/ol>\n<h2>Will more RAM make Lightroom faster?<\/h2>\n<\/p>\n<p>Just don&#8217;t go overboard\u2014even if your processor can support it, 128GB or RAM may not run Lightroom any faster than 32GB or 64GB unless you&#8217;re really overloading your system elsewhere (*cough* Google Chrome *cough*).<\/p>\n<\/p>\n<h2>What is Lightroom library Lrlibrary?<\/h2>\n<\/p>\n<p>An LRLIBRARY file is a photo library created by the macOS version of Adobe Lightroom, a photo editing and organization app. It contains a copy of photos imported into a user&#8217;s Lightroom library, as well as information used to organize those photos.<\/p>\n<\/p>\n<h2>How do I Preview original photos in Lightroom?<\/h2>\n<\/p>\n<ol>\n<li>Select (D) on your keyboard to activate the Develop panel (unless you&#8217;re already there).<\/li>\n<li>Select the (  ) button on your keyboard.<\/li>\n<li>You should now see the original image you took with no edits.<\/li>\n<\/ol>\n<\/p>\n<h2>Can you build smart previews in Lightroom after import?<\/h2>\n<\/p>\n<p>You can always create smart previews after the fact in the Library Module. I will show you how below. Note: If you imported images into Lightroom and chose the smart preview option while housing the files on an external drive, you will see &#8220;smart preview&#8221; listed below the histogram for your image in the Develop module.<\/p>\n<\/p>\n<h2>How do I free up space in Lightroom?<\/h2>\n<\/p>\n<p>You can&#8217;t manually force clearing this cache of images from within Lightroom. Lightroom uses algorithms to decide which photos are \u201cactive\u201d and which are not, and will clear the cached images when it decides they are no longer needed. Delving into Lightroom&#8217;s preferences, you&#8217;ll find this tab under Local Storage.<\/p>\n<\/p>\n<h2>How do I clean up Lightroom?<\/h2>\n<\/p>\n<p>The keyboard combination to Delete Rejected Photos on a Mac is Command + Delete, and on a PC is Control + Backspace. Click whichever is pertinent. Lightroom will ask you to confirm (Figure 2). Click Delete from Disc to permanently delete the images from your computer as well to remove them from your Lightroom Catalog.<\/p>\n<\/p>\n<h2>What happens if I delete my Lightroom catalog?<\/h2>\n<\/p>\n<p>Deleting a Lightroom catalog won&#8217;t affect your original files, but it will delete the specific edits, ratings, previews, keywords, and other meta-data that Lightroom saves in the catalog. If that&#8217;s your goal, then you can safely delete your Lightroom Catalog. Deleting Lightroom catalog backups is a different story.<\/p>\n<\/p>\n<h2>Will deleting photos from Lightroom delete them from my phone?<\/h2>\n<\/p>\n<p>1 Correct answer. Yes deleting from the mobile app will delete them everywhere in the CC ecosystem, so also from lightroom.adobe.com and on any desktop installations of Lightroom CC. It will not delete them from the camera roll when you delete from the mobile app as again those are separate entities.<\/p>\n<\/p>\n<h2>Do you need to keep old Lightroom catalogs?<\/h2>\n<\/p>\n<p>If your situation is anything like mine was, it&#8217;ll have backups all of the way back to when you first installed Lightroom. Delete the ones which you don&#8217;t need anymore. I&#8217;d suggest keeping the latest few, but anything older isn&#8217;t doing anything but taking up space.<\/p>\n<\/p>\n<h2>What are embedded previews in Lightroom?<\/h2>\n<\/p>\n<p>If you use embedded, it just pulls the jpg from the raw data instead of converting and generating one. That means it shows the preview the way the camera stored it; it does not apply whatever profile and presets you normally use in Lightroom.<\/p>\n<\/p>\n<h2>Which processor is best for Lightroom?<\/h2>\n<\/p>\n<p>Currently, the best all-around CPU for most Lightroom Classic tasks is Intel&#8217;s Core i9 12900K. For purely exporting, a higher core count processor like AMD&#8217;s Threadripper or Threadripper Pro will be a little faster &#8211; but for a much higher price and reduced performance in other parts of the workflow.<\/p>\n<\/p>\n<h2>Why is Lightroom so laggy?<\/h2>\n<\/p>\n<p>(3) Your internal hard drive is slow TIP: Lightroom requires lots of free space on your hard drive. If you don&#8217;t have at least 20% of your overall storage space free, that&#8217;s affecting your Lightroom&#8217;s performance, so free up some space asap.<\/p>\n<\/p>\n<h2>Is 8GB of RAM enough for Lightroom?<\/h2>\n<\/p>\n<p>The cost to go to 8GB of memory to 16GB is fairly reasonable and the performance benefits to Lightroom are really worth the additional cost worth it. Lightroom really wants more than 8GB of memory while you process photos. Starting up Lightroom the program immediately takes 1.5GB of memory.<\/p>\n<\/p>\n<h2>Is 4gb RAM enough for Lightroom?<\/h2>\n<\/p>\n<p>At the bare minimum, Lightroom requires 4 GB of RAM to run, but of course, this may not be enough in practical terms when it comes to day-to-day needs.<\/p>\n<\/p>\n<h2>Can I move the Lightroom library Lrlibrary?<\/h2>\n<\/p>\n<p>No, it currently has to be in the default location. The preference you&#8217;re referring to is for setting a different location for any downloaded original images, it doesn&#8217;t affect the location of the local library.<\/p>\n<\/p>\n<h2>Why is my Lightroom library so big?<\/h2>\n<\/p>\n<p>This file can get quite big if you use the Lightroom desktop app as it stores your photo files in this file before it uploads them to Adobe&#8217;s servers. It deletes the photo files after they have been uploaded, which then reduces the Catalog size.<\/p>\n<\/p>\n<h2>What are Lightroom proxies?<\/h2>\n<\/p>\n<p>Lightroom Guru The &#8220;proxies&#8221; are the Smart Previews, so if you have LRCC on one Mac set to store a local copy of all Smart Previews, then that&#8217;s what it does.<\/p>\n<\/p>\n<h2>What are standard previews in Lightroom?<\/h2>\n<\/p>\n<p><iframe style=\"width:100%;height:420px;\" width=\"auto\" height=\"auto\" src=\"https:\/\/www.youtube.com\/embed\/WX9ylv-4s-E\"><\/iframe><\/p>\n<\/p>\n<h2>What is the difference between edited and unedited photos in Lightroom?<\/h2>\n<\/p>\n<ol>\n<li>Use the Show Original button at the bottom, below your filmstrip.<\/li>\n<li>Click into the ellipses underneath your Masking workspace and select Show Original.<\/li>\n<li>Select Show Original from the View tab above.<\/li>\n<li>Hit the forward slash key (  ).<\/li>\n<\/ol>\n<\/p>\n<h2>What is fetching Initial previews Lightroom?<\/h2>\n<\/p>\n<p>That means that Lightroom initially uses the embedded previews made by your camera. Even though that is faster than letting Lightroom render its own previews right away (it will have to do that eventually), it still takes time to read 1000+ images to get these previews.<\/p>\n<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Smart Previews in Lightroom Classic allow you to edit images that are not physically connected to your computer.
