The process version is the Camera Raw technology that Lightroom uses to adjust and render photos in the Develop module. Depending on which process version you use, different options and settings are available to you in the Develop module.
If you’re not sure which process version your image uses, do one of the following:
- Click Settings > Process. A check symbol appears next to the process version used.
- Open the Camera Calibration panel and look at the Process menu.
Process Version 2012
Images edited for the first time in Lightroom 4 use process version 2012. PV2012 offers new tone controls and new tone-mapping algorithms for high-contrast images. With PV2012, you can adjust Highlights, Shadows, Whites, Blacks, Exposure, and Contrast in the Basic panel. You can also apply local corrections for white balance (Temp and Tint), Highlights, Shadows, Noise, and Moiré.
Process Version 2010
Images edited in Lightroom 3 used PV2010 by default. PV2010 offers improved sharpening and noise-reduction from the previous process version, PV2003.
- Click the Update To Current Process 2012 button in the lower-right corner of the histogram (Ctrl/Cmd + 0).
- Click the Update To Current Process 2012 button in the lower-right corner of the photo.
Choose Settings > Process > 2012 (Current).
In the Camera Calibration panel, choose Process > 2012 (Current).
Review Changes Via Before/After
Opens the updated photo in a Before/After view so you can inspect the changes. See View Before and After photos.
Update All Selected Photos
Updates all photos currently selected in the Filmstrip, not just the active photo.
Updating to Process Version 2012 may incur significant visual changes to your photos. It’s a good idea to update images one at a time until you are familiar with the new processing technology.
Soft-proofing is the capability to preview in how onscreen photos appear when printed, and optimize them for a particular output device. Soft-proofing in the Lightroom lets you evaluate how images appear when printed, and adjust them so that you can reduce surprising tone and color shifts.
Use the options in the Soft Proofing panel to see if your colors are in gamut, or range, for your display or output device.
Show/Hide Monitor Gamut Warning
Colors that are outside your display’s color capabilities appear blue in the image preview area.
Show/Hide Destination Gamut Warning
Colors that are outside your printer’s rendering capabilities appear red in the image preview area.
Colors that are outside the gamut of both the monitor and destination device appear pink in the image preview area.
A profile is a mathematical description of a device’s color space. By default, the Lightroom Develop module displays images using your monitor profile. You can simulate a different output color space by choosing it from the Profile menu.
The rendering intent determines how colors are converted from one color space to another.
Perceptual aims to preserve the visual relationship between colors so they are perceived as natural to the human eye, even though the color values may change. Perceptual is suitable for images with lots of saturated, out-of-gamut colors.
Relative compares the extreme highlight of the source color space to that of the destination color space and shifts all colors accordingly. Out-of-gamut colors shift to the closest reproducible colors in the destination space. Relative preserves more of the original colors in an image than Perceptual.
To edit your photo to bring it within a desired color space, click Create Proof Copy. Lightroom creates a virtual copy that you can adjust to print as you desire. Then, make your adjustments.
If you start adjusting photos and forget to click Create Proof Copy, Lightroom asks if you want to create a virtual copy for soft proofing. Click Create Proof Copy to preserve your original image and work on a copy. Click Make This A Proof to edit the original image. Remember that all editing in Lightroom is non-destructive. If you choose to edit the original image, you can still change your mind or undo your changes later.
Apply Develop adjustments to other photos
As you make adjustments to a photo in the Develop module or in the Quick Develop panel of the Library module, Lightroom keeps a record of the settings. You can copy these settings and apply them to different versions of the photo and to other photos selected in the Filmstrip.
You can copy and paste individual Develop settings from the current photo to another photo in Library and Develop modules. To paste settings to multiple photos, you must be in the Library module.
In the Develop module, click the Copy button to the left of the toolbar, choose Edit > Copy, or choose Settings > Copy Settings. Select the settings you want and click Copy.
In the Library module, choose Photo > Develop Settings > Copy Settings. Select the settings you want and click Copy.
(Mac OS) The Edit > Copy command in the Library module copies text and metadata. The Edit > Copy command in the Develop module copies selected text in a panel or copies the Develop settings of a selected photo.
- To paste the copied Develop settings to one other photo, select that photo in the Filmstrip in the Library or Develop module and do one of the following:
In the Develop module, click the Paste button, choose Edit > Paste, or choose Settings > Paste Settings.
In the Library module, choose Photo > Develop Settings > Paste Settings.
(Mac OS) The Edit > Paste command in the Library module pastes copied text and metadata.
The Synchronize command in the Library and Develop modules allows you to apply selected Develop settings of the current photo to other photos in the Filmstrip. (The current photo is indicated by a brighter white border in the Filmstrip thumbnail.)
When only one photo is selected in the Filmstrip, the Sync Settings command is not available. In the Develop module, the Sync button becomes the Previous button; in the Library module, the Sync Settings button is inactive.
- Shift-click or Ctrl-click (Windows) or Command-click (Mac OS) to select other photos in the Filmstrip to synchronize with the current photo, and then do one of the following:
In the Develop module, click the Sync button or choose Settings > Sync Settings. Select the settings to copy and click Synchronize.
In the Develop module, click the Enable Auto Sync switch on the left side of the Sync button to enable Auto Sync mode. Then, drag sliders or make adjustments, and the adjustments are applied to all selected photos.
In the Library module, click the Sync Settings button or choose Photo > Develop Settings > Sync Settings. Select the settings to copy and click Synchronize.
Any settings that you may have previously selected or deselected in the Copy Settings dialog box are also set by default in the Synchronize Settings dialog box.
You can copy all the settings of the photo you last selected in the Filmstrip (even if you didn’t make any adjustments to it) and apply them to the currently selected photo. Do one of the following:
- In the Develop module, click the Previous button to the right of the toolbar, or choose Settings > Paste Settings From Previous.
- In the Library module, choose Photo > Develop Settings > Paste Settings From Previous.
When multiple photos are selected in the Filmstrip, the Previous button in the Develop module turns into the Sync button.
Manage image history and snapshots
During the editing process, you can name and save any state of a photo as a snapshot. Each snapshot you create is listed alphabetically in the Snapshots panel.
Roll the pointer over the list of snapshots to preview each one in the Navigator.
Do not press the Delete key on your keyboard; this will delete the currently selected photo.
The History panel keeps a record of the date and time that a photo was imported into Lightroom, including any preset that was applied at the time. Afterward, whenever you make an adjustment to the photo, Lightroom saves that adjustment as a state and lists it with all the other states chronologically in the History panel. You can change the names of the states, but you cannot change the order in which they are listed.
- Preview each state of the photo by rolling the pointer over the list in the History panel and viewing the effects in the Navigator panel.
- Select a state in the History panel to reapply it to the photo or to save it as a snapshot.
- Double-click a state to select its name, type a new name, and press Enter or Return.
- Right-click (Windows) or Control-click (Mac OS) a state and choose Copy History Step Settings To Before to copy a single adjustment.
- Click the Clear All button (the X) on the History panel header to remove all states from the listing.
When the list of states gets too long in the History panel, create snapshots of the states you want to keep. Then, clear the panel by clicking the Clear All button. This removes the list of states without affecting the current image settings.
