Process versions
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.
Process Version 2003 The original processing engine, used by Lightroom 1 and 2.

• 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).

Update All Filmstrip Photos Updates all photos in the Filmstrip, not just the one that is selected.
Note: 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-proof images
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.
1 With an image open in the Develop module, select the Soft Proofing box in the toolbar.
The preview background turns white, a Proof Preview label appears in the upper-right corner of the preview area,
and the Soft Proofing panel opens.
