By default, Lightroom Develop module settings are stored in the Lightroom database. In order to ensure that Lightroom Develop settings can be viewed by Camera Raw 6.1, the settings must be written to the XMP metadata block for that file. This metadata is stored in an XMP sidecar file (imagename.xmp) in the path of the proprietary raw files, or stored directly within DNG files. To update images with the latest Develop settings, go to the Library module and select the group of images. Press Ctrl+S (Windows) or Command+S (Mac OS) to save the settings to the XMP metadata block. See About metadata and XMP in Lightroom Help.
Viewing Lightroom settings in Camera Raw 6.1
Before working with Lightroom and Camera Raw, set the Camera Raw preference to Save Image Settings In Sidecar ".Xmp" Files. By default, Camera Raw will display the image adjustments exactly as performed in the Lightroom Develop module. See Work with Camera Raw and Lightroom in Camera Raw Help.
