Export Camera Raw settings and DNG previews
If you store file settings in the Camera Raw database, you can use the Export Settings To XMP command to copy the
settings to sidecar XMP files or embed them in DNG files. This is useful for preserving the image settings with your
camera raw files when you move them.
You can also update the JPEG previews embedded in DNG files.
1 Open the files in the Camera Raw dialog box.
2 If you are exporting settings or previews for multiple files, select their thumbnails in the Filmstrip view.
3 In the Camera Raw Settings menu , choose Export Settings To XMP or Update DNG Previews.
The sidecar XMP files are created in the same folder as the camera raw image files. If you saved the camera raw image
files in DNG format, the settings are embedded in the DNG files themselves.
Specify Camera Raw workflow options
Workflow options specify settings for all files output from Camera Raw, including the color bit depth, color space,
output sharpening, and pixel dimensions. Workflow options determine how Photoshop opens these files, but do not
affect how After Effects imports a camera raw file. Workflow options settings do not affect the camera raw data itself.
You can specify workflow options settings by clicking the underlined text at the bottom of the Camera Raw dialog box.
Space Specifies the target color profile. Generally, set Space to the color profile you use for your Photoshop RGB
working space. The source profile for camera raw image files is usually the camera-native color space. The profiles
listed in the Space menu are built in to Camera Raw. To use a color space that’s not listed in the Space menu, choose
ProPhoto RGB, and then convert to the working space of your choice when the file opens in Photoshop.
Depth Specifies whether the file opens as an 8-bpc or 16-bpc image in Photoshop.
Size Specifies the pixel dimensions of the image when imported into Photoshop. The default pixel dimensions are
those used to photograph the image. To resample the image, use the Size menu.
For square-pixel cameras, choosing a smaller-than-native size can speed processing when you are planning a smaller
final image. Picking a larger size is like upsampling in Photoshop.
For non-square pixel cameras, the native size is the size that most closely preserves the total pixel count. Selecting a
different size minimizes the resampling that Camera Raw performs, resulting in slightly higher image quality. The best
quality size is marked with an asterisk (*) in the Size menu.
Note: You can always change the pixel size of the image after it opens in Photoshop.
Resolution Specifies the resolution at which the image is printed. This setting does not affect the pixel dimensions. For
example, a 2048 x 1536 pixel image, when printed at 72 dpi, is approximately 28-1/2 x 21-1/4 inches. When printed at
300 dpi, the same image is approximately 6-3/4 x 5-1/8 inches. You can also use the Image Size command to adjust
resolution in Photoshop.
Sharpen For Allows you to apply output sharpening for Screen, Matte Paper, or Glossy Paper. If you apply output
sharpening, you can change the Amount pop-up menu to Low or High to decrease or increase the amount of
sharpening applied. In most cases, you can leave the Amount set to the default option, Standard.
Open In Photoshop As Smart Objects Causes Camera Raw images to open in Photoshop as a Smart Object layer
instead of a background layer when you click the Open button. To override this preference for selected images, press
Shift when clicking Open.
