Adobe Announces February Update to Lightroom Classic (7.2) 

While this update of Lightroom Classic (7.2) focuses primarily on performance enhancements such as batch processing, I’m excited that the team has also added several small, yet powerful features, to help us quickly find our images in the Library module and more!

Performance Enhancements

First, by working with our partners at Intel, the team was able to make significant strides to increase the performance of multi-core machines that have 12GB (or more) of RAM. Regardless of how many cores your machine has, the code that optimizes CPU and memory usage is scalable so you will see improvements, but in general, if you have small number of cores, you will see a smaller increase in performance than if you have more cores (in which case you should see a larger increase in performance).

Here are the areas where you should see the largest performance gains:

• Faster  import, auto import, preview generation and export

• Faster moving from one image to the next in Loupe View and the Develop module

• Faster rendering of adjustments in Develop

• Faster batch merge operations of HDR/Panos

• Functions in the app (such as preview creation on import and batch exporting), will not slow down over time or with extended use (particularly on Windows machines).

Five New Library Module Features

1) Filter/Search the Folder Panel

To quickly find a folder (especially those that might be burred deep within your hierarchy of folders and subfolders), click in the Filter/Search bar at the top of the Folders panel and start typing.

2) Favorite Folders

If you have folders that you return to time and again, Control -click (Mac) | Right -click on a folder and choose Mark Favorite from the context sensitive menu. Use the Folder Panel’s Search menu to view your favorites.

Folders marked as Favorites can be accessed across all modules by selecting them from the black bar at the top of the Filmstrip.

3) Create Collections and Collection Sets from Folders

There are several options for converting folders to collections – including (or not), Collection Sets making it easier then ever to sync your collections across mobile devices:

• To create a collection from a folder, drag the folder from the folder panel to the Collections panel. Or, Control -click (Mac) or Right -click on the folder and choose Create Collection “folder name”.

• To convert a folder with subfolders to a Collection Set with collections that maintain the same hierarchy as the folders, Control -click (Mac) or Right -click on the parent folder (the one that has subfolders) and choose Create Collection Set “folder name”.

• To create a single collection of all of the photos from a parent folder (including images within subfolders), Control -click (Mac) or Right -click on the parent folder and choose Create Collection “folder name”.

4) Filter on Edited and Unedited images

To quickly find images that are edited or unedited (this includes having a crop applied), in Grid view, do one of the following:

• Click Attribute in the Filter Bar. Click one of the Edits icons (Edited or Unedited) to filter.

• Click Metadata in the Filter Bar. Click the name of a column header and choose Edit from the list. Choose  Edited or Unedited images to filter.

5) New Smart Collection Rule

A new rule (Has Edits), has been added to the Develop category in Smart Collections. Selecting “Has Edits” displays images that have adjustments applied and/or cropping but excludes images that only have adjustments (and no crop) applied. Note: to create a Smart Collection which includes only with adjustments (and ignores the crop), choose “Has Adjustments” instead.

New Map Module Feature

You can easily create a collection based a group of photos at a specific Pin location. Control -click (Mac) | Right -click on the pin and select New Collection from the context sensitive menus.

This release also includes additional camera raw support, lens profile support, and addresses bugs that were introduced in previous releases of Lightroom.

Adobe Announces Updates to the Lightroom CC Family of Products

I’m excited to announce a brand new addition to the Lightroom CC family of products as well as several updates and new features to Lightroom on mobile and web!

The All-New Lightroom CC

The all-new Lightroom CC is designed to complete a cloud-based ecosystem of apps that are deeply integrated and work together seamlessly across desktop, mobile, and web.

As a result, the the desktop-centric product you’ve known as Lightroom will be rebranded “Lightroom Classic CC”.

Watch this video to find out more about the all-new Lightroom CC.

 In addition, this video, discusses which of the Lightroom applications, Lightroom CC —the cloud-centric photo service, or Lightroom Classic —the desktop-centric app is best for your workflow.
For more information, be sure to watch this series on Lightroom CC by Josh Haftel.
Lightroom Classic CC

There have been several updates to Lightroom Classic including significant performance improvements in a number of areas including:

  • Application launch time
  • Preview generation
  • Switching between Library and Develop Module
  • Moving from photo to photo in the Develop Module
  • Painting using the Adjustment Brush

Check out this video to discover how to preview images faster than ever before using Lightroom Classic’s new Embedded Preview workflow.

Note: setting the Auto Import’s Initial Previews to Embedded & Sidecar will also take advantage of the new Embedded Preview workflow.  

 This video demonstrated the power of the new Color and Luminance Range Masking features to quickly make precision adjustments using the Adjustment Brush, Radial, and Graduated Filters.
Note: Lightroom Classic will need to update catalog from previous versions of the application . This help document (Upgrade a catalog from an earlier version of Lightroom Classic CC) provides additional information about catalogs.

Lightroom CC on Mobile Devices

Several new features and product enhancements have been made to Lightroom on mobile devices. On both iOS and Android, you can now search through your synced photos using Adobe Sensei to find images based on image content —without having to tag or keyword them.

Or, add add your own custom keywords, using the new Keywords menu.


To  keep track of your photographs, create albums and organize them in folders.

On iOS:

Lightroom for mobile has been optimized for iOS 11, enabling access to any photos that are available within the Files app.
On iPads running iOS 11, you can now drag and drop photos (including raw photos), from any other app, directly into Lightroom for mobile, to import.

On Android:

Lightroom for mobile has been optimized for the latest version of Android OS, Android O.
In addition, Lightroom for mobile has been optimized for Chromebooks, with a new interface that provides an optimal editing experience for devices with keyboards, as well as trackpads and touch interfaces.
And finally, use the Selective Brush to enhance your photos.

Lightroom on Web

You can now create a single gallery that hosts multiple albums to share with friends, family, and clients. The galleries are “live” representations of your images so if you edit your photographs, the galleries automatically update.

In addition, check out the new Tech preview – Best Photos which leverages a number of Adobe Sensei technologies to help automatically identify and group similar photos, and then select the best photos of each of the groups.

Multiple Undo in Photoshop

• Command + Z (Mac) | Control  + Z (Win) will toggle undo/redo of the last command.

• Option + Command  + Z (Mac) | Alt + Control + Z (Win) will step you back through history.

• Command + Shift + Z (Mac) | Control + Shift + Z (Win) will step you forward through history.

To change the number of history states (multiple undo’s) that Photoshop keeps track of while an image is open, select Preferences > Performance and enter a value for History States. Setting a higher number (100 for example) will save more changes, and allow you to step farther back in time, however it will also require Photoshop to keep track of more information in RAM (or, when all of the RAM is in use, using the scratch disk). Making large changes to the entire document (adding layers, running filters etc.), requires keeping track of more history than smaller changes (such as small, localized strokes with the Healing Brush). Therefore, if you increase the number of states and notice a performance hit, trying lowering the number again.

You can also manually set the Cache Levels and Cache Tile Size in the Performance Preferences. If you use relatively small files—roughly 1 megapixel or 1280 by 1024 pixels—and many layers (50 or more), set Cache Levels to 1 or 2. Setting Cache Levels to 1 disables image caching; only the current screen image is cached (however, you may not get high-quality results with some Photoshop features if you set Cache Levels to 1). If you use files with larger pixel dimensions—say, 50 megapixels or larger—set Cache Levels higher than 4. Higher cache levels speed up redrawing.

Lightroom Mobile and Smart Previews

After yesterdays release of Lightroom mobile, I want to reiterate that when you sync a collection of images from Lightroom on the desktop to Lightroom mobile we are syncing Smart Previews – not the entire raw files. This means that you should not think of Lightroom mobile as a “backup solution”. 

There are a number of reasons for using Smart Previews in today’s workflow including; bandwidth, speed, performance, and storage space. So although you might have thought that Smart Previews were only useful for working with off-line files, now you know that they were designed for and specifically optimized to be used on a mobile device.

And don’t worry, Lightroom will create Smart Previews for the images that you choose to sync automatically, so you don’t have to do a thing.
