I’m excited to announce the new features and latest updates in Lightroom Classic 8.4 including GPU accelerated image editing, improved performance in the Folder Panel, Color Labels for Collections, Export to PNG, Batch Photo Merge for stacked images and more!
GPU Accelerated Image Editing Lightroom Classic now takes advantage of the computer’s graphics processing unit (GPU) when processing images, making editing more responsive than ever before. This can be especially helpful when working on images with multiple edits and/or when viewing images on 4K and higher resolution monitors. Use the new options under Preferences > Performance to determine what features use the GPU:
Auto – checks the system (a combination of OS version, GPU and GPU driver version) and uses the GPU for both display visualization and image processing when possible.
Custom – provides options to have the GPU only accelerate the display of images (“Use GPU for display” ), or accelerate both the display and image processing (“Use GPU for image processing”). Note: “Use GPU for display” is the equivalent of GPU acceleration “ON” in earlier versions of Lightroom Classic
Off – disables GPU acceleration for all features.
Note: Only images using Process Version 5 (PV5) or higher will be accelerated by the GPU. To update an image to PV5, in the Develop module, click the lightening bolt icon under the Histogram or, select “Version 5 (Current)” from the Process drop-down menu in the Calibration panel.
Export as PNG When exporting files, you can now choose the PNG file format.
Batch Process Photo Merge Commands The Photo Merge commands (HDR/Pano/HDR-Pano) now support the merging of “stacks” of images. First, select the images to be stacked (for example, three bracketed exposures that need to be merged to HDR), and stack them (Command + G (Mac) | Control + G (Win)). Then, select multiple stacks and choose Photo > Photo Merge and select the desired Photo Merge option.
Each stack will be merged individually with the selected merge operation. Note: the same merge operation will be performed on all the stacks – so only choose stacks of images that need to be merged to Panoramas or to HDR or to HDR Panoramas, not a mix of different types of merges). When more than one stack is selected, Lightroom Classic uses the “previously used” settings from the dialog and, if a mix of stacked and unstacked images are selected when choosing Photo Merge, non-stacked images will be ignored.
Color Labels for Collections and Published Collections You can now assign Color Labels to Collections, Smart Collections, Collection Sets and Published Collections by Control -clicking (Mac) | right -clicking (Win) the collection and selecting “Add Color Label” from the context sensitive menu. Then, use the “filter by” drop down menu in the Collections panel to filter based on the labeled collections (same as the Labeled Folders in the Folders Panel). To remove a color label, Control -click (Mac) | right -click (Win) and select “None” from the “Add Color Label” option.
Custom Color Labels Sets Previously changing the name of color labels was a global operation, now you can assign different names to color labels for Images, Folders, and Collections by selecting Metadata > Color Label Sets.
Note: if you have created Smart Collections based on images that have a color label (such as “red” )and then change the name of the images color label (to “Portfolios”, for example), all images that were previously labeled with the color red will change to the color white and any smart collections that are set to match “Color Label > Is > Red” will become empty (although they can still be found by selecting the metadata tab in the Library Filter bar and setting the column to Label).
Faster Calculation of Image Count in Folders When launching Lightroom Classic, the amount of time that it takes to calculate the number of images within each folder should be decreased.
Auto-Create Cell in Book Module Drag and drop a photo from the filmstrip (or from any photo cell), to a page will automatically create a new cell for the photo.
Smarter Profiles and Presets Handling Lightroom now displays error/warning dialogs if a set of presets has already been imported, if the .zip being imported is password protected, and/or if the .zip being imported has neither a preset nor a profile within it.
Index Number Displayed in Filmstrip Select Preferences > Interface to display the Index Number in the Filmstrip (this works like Index Numbers in Library Grid).
Better Rendering of Web Content The Map and Web modules have been updated to better render web content.
Deleted Synced Files While there isn’t a “Deleted Files Bin” in Lightroom Classic like there is in Lightroom, Lightroom Mobile, and Lightroom Web, any synced photos that you un-sync from Classic will still end up in the Deleted Files bin shared by the other clients.
This release also includes additional camera raw support, lens profile support, and addresses bugs that were introduced in previous releases of Lightroom.
