In the Save Options dialog box, specify the following options:
Specifies where to save the file. If necessary, click the Select Folder button and navigate to the location.

Specifies the filename using a naming convention that includes elements such as date and camera serial
File Naming
number. Using informative filenames based on a naming convention helps you keep image files organized.
Choose a file format from the Format menu.

Saves a copy of the camera raw file in the DNG file format.

Specifies the versions of Camera Raw and Lightroom that can read the file. Use the tool tips to help
Compatibility
you choose.
If you choose Custom, specify whether you want compatibility with DNG 1.1 or DNG 1.3. By default, the conversion
uses lossless compression, which means no information is lost while reducing file size. Choosing Linear (Demosaiced)
stores the image data in an interpolated format. That means other software can read the file even if that software does
not have a profile for the digital camera that captured the image.
•
Embeds a JPEG preview in the DNG file. If you decide to embed a JPEG preview, you can choose the
JPEG Preview
preview size. If you embed JPEG previews, other applications can view the contents of the DNG file without parsing
the camera raw data.

Embed Original Raw File
Saves copies of the camera raw files in JPEG (Joint Photographic Experts Group) format. To specify the amount
JPEG
of compression, enter a value from 0 to 12 or choose from the menu. Entering a higher value, or choosing High or
Maximum, applies less compression and increases file size and image quality. JPEG format is commonly used to
display photographs and other continuous-tone images in web photo galleries, slide shows, presentations, and other
online services.
Saves copies of the camera raw files as TIFF (Tagged-Image File Format) files. Specify whether to apply no
TIFF
compression, or LZW or ZIP file compression. TIFF is a flexible bitmap image format supported by virtually all paint,
image-editing, and page-layout applications. TIFF provides greater compression and compatibility with other
applications than does PSD format.
Saves copies of the camera raw files in the PSD file format. You can specify whether to preserve cropped
Photoshop
pixel data in the PSD file.

Making color and tonal adjustments in Camera Raw
Histogram and RGB levels in Camera Raw
A histogram is a representation of the number of pixels at each luminance value in an image. A histogram that has
nonzero values for each luminance value indicates an image that takes advantage of the full tonal scale. A histogram
that doesn't use the full tonal range corresponds to a dull image that lacks contrast. A histogram with a spike at the left
side indicates shadow clipping; a histogram with a spike on the right side indicates highlight clipping.
Select Shadows or Highlights to see, in the preview image, which pixels are being clipped. For more information, see
"Preview highlight and shadow clipping in Camera
One common task for adjusting an image is to spread out the pixel values more evenly from left to right on the
histogram, instead of having them bunched up at one end or the other.
Stores all of the original camera raw image data in the DNG file.
