Lightroom Classic Desktop April Update – Raw & Creative Profiles, Preset Updates, and More!

I’m excited to announce several updates to Lightroom Classic starting with the new and enhanced Raw and Creative Profiles. While the concept of Profiles isn’t new to Lightroom Classic, in this release, their power has been greatly enhanced. This video demonstrates how:

If you’re not familiar with raw profiles, here is a overview of the key concepts covered in the video above:


A profile is a set of instructions that is used to render a photograph, converting it from raw camera information into the colors and tones that we see. 

  • Every raw image must have a profile applied (and can only have one profile at a time).  
  • Profiles are nondestructive and can be changed  at any time without any loss of quality.

Previous to this release, Adobe applied the Adobe Standard profile (v2) to all raw files by default. While a few customers changed their default profile (to a camera matching profile for example), the majority of customers, the application of a profile just happened magically. 

  • In this release, profiles have been moved from the Camera Calibration tab to the Basic tab, making them easier to access. 

  • There are no “right” or wrong” profiles: they’re like filling in a pie – some people will choose cherry and others prefer peach.

Adobe Raw Profiles

There are six new Adobe Raw profiles which can be applied to raw files. The new default profile for raw files in Lightroom Classic is Adobe Color for color images and Adobe Monochrome for Black & White images.  

Adobe Color — was designed to be a great starting point for any image. The goal of this profile is to render a relatively neutral, baseline image that closely matches the original colors and tones in the original scene. It assumes that you want the ultimate control over refining and adjusting images in order to achieve the exact look that you want. In comparison to the previous default profile, Adobe Color is a bit warmer in the reds, yellow and oranges, has a very small increase in contrast, and, it does a better job of moving highlights between color spaces.  

Adobe Monochrome — ­was carefully tuned to be the best starting point for any black and white image. This profile slightly shifts colors as they are converted to grayscale – brightening the warmer colors and darkening the cooler colors. It also adds a small amount of contrast but allows lots of headroom for editing.  

The additional four Adobe Raw profiles that were created as starting points for specific types of images:

Top row left to right: Landscape, Neutral. Bottom Row left to right: Portrait, Vivid.

Adobe Landscape — ­adds a bit more saturation to all of the colors in an image and renders more vibrant blues and greens. While this profile adds a slight amount of contrast to the overall image, it also helps to maintain details by slightly compressing the  highlight and shadow values in scenes with significant contrast.

Adobe Neutral — ­reduces color saturation as well as contrast , rendering a flatter, low contrast version of the image. It‘s designed to give you the most headroom for post processing. This a great profile to start with if you have an image with delicate colors and gradients. 

Adobe Portrait — ­is tailored especially for portrait images. It has a slightly more gentle tone curve and is optimized for skin tones.  

Adobe Vivid — ­adds vibrance and contrast while still rendering natural skin tones and is a great place to start for images of people in a landscape.

Note: Standard V2 was the default profile in previous versions of Lightroom Classic.

If the image that you’re working with isn’t set to Adobe Color by default, most likely one of three things is happening:

You’re working on a non-raw photograph (like a JPEG or TIFF) – in which case the profile will just say Color because all of the rendering was done already (either in another raw processor or within the camera itself) and you can’t apply a raw profile to a non-raw file.

You’re working on an image captured as DNG via Lightroom on a mobile device and the default profile is Camera Default because images are be optimized differently for images captured on mobile devices. 

You’re working with a legacy file – in which case you will see the previously embedded profile which you can choose to change at any time (Lightroom won’t automatically update legacy files using the new profiles as doing so would change the look of the image.)

Adobe Camera Matching Raw Profiles 

In addition, Adobe created and ships Adobe Camera Matching profiles. These profiles are designed to match the preset “styles” that can be set using the menus on a camera. Because the style options differ among camera manufacturers, this list of profiles will change depending on your camera.

Adobe Camera Matching Profiles for the Canon 5Ds. Top row left to right: Faithful, Landscape, Neutral. Bottom Row left to right: Portrait, Standard, Monochrome. 

The Camera Matching monochrome profiles behave differently from other Black and White profiles (Adobe Monochrome, Legacy, and the Creative Profiles), by discarding the color information in the file. Therefore, the Black and White Mix sliders, are not available. You can however add color tints to these images using the Tone Curve, Split Tone, and color swatch with Local Adjustment tools. 

Legacy Raw Profiles 

Legacy Raw profiles are also included in order to maintain backwards compatibility when working with legacy files. 

Creative Profiles

In addition to Raw profiles, are several groups of  Creative profiles. These profiles are designed to apply more creative, stylistic effects to an image and can be applied to non-raw photographs (like JPEG’s and TIFFs). Creative Profiles can (but aren’t required to) use color lookup tables (LUTs) to remap color and tones enabling new and unique ways of processing images. Lightroom ships with several different Creative profiles including:

Artistic Profiles these profiles were designed to be more edgy, and typically have stronger color shifts. 

Lightroom’s eight different Artistic profiles.

B & W Profilesthese profiles were designed to create a more dramatic interpretation of the original image, some of these profiles increase/decrease contrast, others limit the dynamic range, and several emulate the effects of using color filters with film.  

An assortment of different Black and White profiles (01, 03, 06, 07, 08, 11, red, blue).

Modern Profiles these profiles were designed to create unique effects that fit in with current photography styles.

An assortment of different Modern profiles (1, 2, 3, 4, 5, 6, 8, 10).

Vintage Profiles these profiles were designed to replicate the effects of analogue imagery.

An assortment of different Vintage profiles (1, 2, 4, 6, 7, 8, 9, 10).

Creative profiles have an Amount slider which can be used to decrease/increase the intensity of the profile.  Note:  it is up to the creator of the profile to define exactly how far the “intensity” can be changed. In other words, you might see subtle or more aggressive changes on a per-profile basis.


Previewing and Applying Profiles

You can hover the cursor above a profile to preview the effect in the preview area, however you need to click the profile to apply it (as well as preview an accurate rendition of the image in the Histogram Panel).

Double click a profile to simultaneously apply it as well as close the Profile Browser.

Once a profile has been applied, use any of the other slider controls in any of the other panels to make additional modifications to your images. Profiles don’t change slider values. 

Quickly Accessing Favorite Profiles

Click the star icon to add a profile to the Favorites group. Click the star again to remove it.

Quickly access Favorites from the Profile drop-down menu (without having to use the Profile Browser).

Including Profiles in a preset

When saving a preset, you can choose to include Treatment & Profile to save the profile as a part of a preset (just as you would any other attribute or setting in Lightroom). 

A number of additional features have been updated in Lightroom Classic including:

Preset Enhancements

Presets are now saved as XMP files, making them compatible  and accessible across all of the Lightroom products, Camera Raw, and Camera Raw as a filter in Photoshop. Existing presets are converted to XMP as part of a catalog upgrade or during the launch process. Note: presets will be renamed in the OS by adding “~” to the start of the filename, but the name of the preset will not change in Lightroom. 


The Dehaze slider has moved from the Effects to Basic Panel and in Copy Settings and Preset creation dialogs, Dehaze is under Basic Tone.

Tone Curve

The Tone Curve Panel has been expanded for more precise adjustments.

Import Grid Performance Improvement on Windows 

When importing images from connected devices, images will appear in the Import Grid in batches, even before all of the images have completed scanning,

Face Tagging 

The Face Tagging engine has been updated to provide better face detection and recognition and includes has two new options:  “Skip over photos that have not been previously indexed” and “Skip over photos with manually confirmed faces”, when selecting Library > Find Faces Again. 

This release also contains big fixes and added support for new cameras and lenses.

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.
