Adobe Lightroom Classic 8.4 & Camera Raw 11.4 | August 2019

The latest updates Adobe Lightroom Classic and Camera Raw were released to customers on  13 August. These updates focus on performance, workflow, support for new camera and lenses, and bug fixes.

The headline feature in this update to Lightroom Classic and Camera Raw is Graphics Processor Accelerated Editing. In particular, the ability to take greater advantage of features built into today’s more advanced graphics cards (GPUs) while editing your photos. Other new features to be found in Lightroom Classic 8.4 are: support for PNG export, colour labels in collections, batch merge of stacks for HDR, Panoramas and HDR Panoramas

GPU Accelerated Editing

Adobe are advising customers that GPU support now includes the ability to improve interactive performance while processing photos. Hmm, I seem to recall reading something similar with Lightroom 6 then again with Lightroom 7. So, what’s new?

In previous versions, the GPU was used to accelerate the drawing or ‘display’ of pixels processed by the CPU, although many users felt that it fell short of doing so. With Lightroom Classic 8.4/ Camera Raw 11.4 the ‘image’ processing has been to the GPU Compute shaders. This means that the raw photo ‘processing pipe‘ has been ported to the GPU. As such, most of the image adjustments (e.g. Exposure, Contrast, White Balance, Clarity, Dehaze, etc ) can now be computed by the GPU rather than the CPU.

Typically, when ‘full’ acceleration is enabled you will notice that the adjustment sliders in Lightroom Classic and Camera Raw are smoother and more responsive. Additionally, the affects of ‘full’ acceleration will be more  pronounced when using higher resolution displays (i.e. 4k and above).

Update – 14 August 2019

A number of recent messages to Adobes Lightroom Classic User forum have confirmed that eGPUs are supported on the Mac platform, To enable  ‘Full GPU Acceleration’ the monitor needs to be connected to a Thunderbolt 3 port on the eGPU and the OS update to macOS Mojave 10.14.6, although earlier versions of Mojave might also work.

On Windows platform it’s important that the computer is running Windows 10 and that DirectX 12 is operational. Users should also ensure that they’re using the latest GPU driver, especially if its an nVidia card. 

The feature is enabled from within the Preferences dialog under the Performance tab in both Lightroom Classic and with Camera Raw.

When you access the Performance tab, you’ll immediately notice that the Graphic Processor segment now includes 3 dropdown options:

  1. Auto
  2. Custom
  3. Off

With ‘Auto’

Both Lightroom Classic 8.4 and Camera Raw 11.4 check the capabilities of the GPU upon first launch. If the GPU fails the test for any reason then GPU support will be set to Off.

Assuming your graphics card passes the test, is supported (i.e. not on the Adobe GPU Black List) and the operating system meets the minimum requirements, then ‘Auto’ will be enabled. However, the dialog may indicate that only ‘Basic’ acceleration is enabled. This is demonstrated in below screenshot from Camera Raw 11.4.

Camera Raw 11.4 – Performance Tab

This may be due to a number of reasons, but the most common are: the GPU has not been internally tested by Adobe engineers or the photos are ‘Process Version 4’ or earlier, but don’t despair just yet ‘Custom’ might yet come to the rescue.

With the ‘Custom’ option, you can select between the following options:

  1. Use GPU for display visualisation, which is same as GPU acceleration ‘ON as in earlier versions of Lightroom Classic and Camera Raw.
  2. Use GPU for image processing.

If you have ‘Use Graphics Processor set to ‘Auto’ and the text under the GPU name indicates ‘Your system automatically supports basic acceleration’ then, follow the following steps to enable Full Acceleration:

  1. Preferences > Performance Tab
  2. Select ‘Custom’ from ‘Use Graphics Processor’
  3. Check ‘Use GPU for image processing’ checkbox.

If your GPU supports full image processing, then the text under the GPU name will indicate ‘Full graphics acceleration is enabled’. This is demonstrated in below screenshot from Lightroom Classic 8.4

Lightroom Class – Performance Tab

If the text indicates that your GPU doesn’t support ‘full’ graphics acceleration, then at least you can still take advantage of  basic acceleration.

Colour Labels for Collections

Support for colour labels in folders was first introduced June 2018. With version 8.4 colour labels have been added to Collections, Smart Collections and Collection Sets.

Lightroom Classic 8.4 – Coloured Labels for Collections

  • To apply a Colour Label to a Collection, a Smart Collection, or a Collection Set, a new option has been added in the context menu as ‘Add Colour Label’.

Add Coloured Labels to Collection

  • To remove a colour label, select ‘None’ from the ‘Add Colour Label’ option.
  • Colour Labels now can also be added to Published Collections and collections inside Publish Services.
  • You can can also filter the Labeled Collections in the same way as Labeled Folders.

Filter Coloured Labels in Collection

Photo Merge – Support for merging multiple stacks

Photo merge now supports merging multiple selected stacks.

When you select multiple stacks for a merge operation (HDR/Pano/HDR-Pano), each stack will be merged individually with the selected merge operation. For example, if one selects 10 stacks for HDR merge operation, Lightroom Classic will initiate 10 HDR merge operations – one for each stack.

Photo Merge Multiple Stacks


  •  The same merge operation will be performed on all the stacks.
  • No preview will be shown if more than one stack is detected. Previous settings will be used as in case of a headless merge.
  • Non-stacked images will be ignored if stacks are detected in input images

Other Enhancements

Folder Enumeration Performance Improvements

With this build, Adobe have worked on the improving time taken for folder enumeration when Lightroom Classic is launched. This particular performance improvement depends on complexity of folder structure, but in most cases users should see a very obvious reduction in time taken to display the number of photos in a folder compared to that taken in previous versions.

Cloud Sync – Diagnostic Report

You are now able to generate a detailed Diagnostic Report for Sync in Lightroom Classic. This report is saved to a zip file with the catalog info, sync data and diagnostic logs required for Adobe QE to establish the cause of the sync issue.

To generate Diagnostic Report, in Preferences go to Lightroom Sync tab and press ALT/OPTIONkey to see “Generate Diagnostic Report” button

Filmstrip Index Number

It’s now possible to display the Index Number of a photo in the Filmstrip. This works like Index Numbers in Library Grid. On a scale of usefulness, I rate this about 100 (negative), but some users obviously thought it worthy of a feature request.

Filmstrip Index Number

In the flesh, the Index Number appears as shown in below screenshot. However, as the strip size is reduce there is a point at which the index number and the badges disappear.  Contrary to what some have claimed in the past, this is not a bug. It’s giving priority to the thumbnail (i.e. the photo) rather that some superfluous information that’s of little real value. Is it obvious that I think this feature was a waste of time?

Export as PNG

With this build, Adobe have added ability to Export as PNG. Save Transparency is always on.

Adobe Lightroom 2.4 Cloud-Centric Photo Service | August 2019

The latest update to the Adobe Lightroom Cloud-centric suite of applications was released to customers on  13 August. This update mainly focuses on a feature that enables users to recover deleted photos. It also includes support for new cameras and lenses, and bug fixes.

Recover Deleted Photos

Recovery of ‘accidentally’ deleted photos, which includes entire photo libraries, has been a long standing request (demand?) from customers since the early days of the mobile ecosystem. With this latest update, all applications within the Lightroom cloud-centric ecosystem now have a folder called ‘Deleted’. Basically, any photos deleted by the user are transferred to this folder, which at time of writing, does not count against cloud storage capacity. The photos will remain in the ‘Deleted’ folder for 60 days or until they’re permanently deleted or recovered.

Using the following series of screenshots and text I will go through the process of deleting some photos, then recovering them.

Adobe Lightroom 2.4 (Desktop)

  • As mentioned above, when photos are deleted we’re notified of how many and given the choice to cancel out or proceed.

Delete Photos Dialog

  • In below screenshot, I show that the 41 photos have been moved to the ‘Deleted’ folder in the desktop application and Lightroom on the web. This is also repeated on my mobile devices (i.e. iPhone and iPad).

‘Deleted’ Photos folder on Lightroom Desktop and Web

Having deleted the photos I realise that I’d really meant to remove them from Lightroom rather than put them in the trash. In previous versions of all apps within the Lightroom cloud-centric ecosystem the deleted photos could not be recovered, but Adobe has now provided a recovery tool that can be used with the desktop application, the web based application and our mobile devices. It’s also relatively simple to use.

Now to recover the deleted photos, but first let’s also check out the options available.

  • First, I right mouse-click on the ‘Deleted’ folder.

‘Deleted’ folder context menu

  • For this example, I choose ‘Restore All’

Restore deleted photos

  • In below screenshots we see that the 41 photos that I’d deleted earlier have been recovered and even put back into their original album.

Recovered Photos (Desktop application)

Recovered Photos (Web application)

  • The number of days left before the photos are permanently deleted is also shown.

Days left before permanent deletion

As can be seen from above, the process of recovering deleted photos is relatively fast and simple when using only those applications that are part of the Lightroom cloud-centric ecosystem. If, on the other hand, you’re also using Lightroom Classic, which Adobe actually recommends against, then the process of recovery is somewhat more complex and time consuming.
