The process version is the technology that Camera Raw uses to adjust and render photos. Depending on which process version you use, different options and settings area available to you in the Basic tab and when you make local adjustments.
Process Version 2012
Images edited for the first time in Camera Raw 7 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 Camera Raw 6 used PV2010 by default. PV2010 offers improved sharpening and noise-reduction from the previous process version, PV2003.
To take advantage of the newer processing, you can update previously edited photos to the current process version.
- Click the Update to Current Process button (the exclamation-point icon) in the lower-right corner of the image preview.
