Alt-click (Windows) or Option-click (Mac OS) Save to suppress the Camera Raw Save Options dialog box when
saving a file.

2

In the Save Options dialog box, specify the following options:

Destination

Specifies where to save the file. If necessary, click the Select Folder button and navigate to the location.

File Naming

Specifies the file name using a naming convention that includes elements such as date and camera serial

number. Using informative file names based on a naming convention helps you keep image files organized.

3

Choose a file format from the Format menu.

4

Click Save.

Format options

Digital Negative

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

Compressed (lossless)

Uses lossless compression, meaning that no information is lost while reducing the file size.

Convert To Linear Image

Stores the image data in an interpolated (demosaiced) format. The resulting interpolated

image can be interpreted by other software even if that software does not have a profile for the digital camera that
captured the image.

Embed Original Raw File

Stores all of the original camera raw image data in the DNG file.

JPEG Preview

Embeds a JPEG preview in the DNG file. If you decide to embed a JPEG preview, you can choose

the preview size. If you embed JPEG previews, other applications can view the contents of the DNG file without
parsing the camera raw data.

JPEG

Saves copies of the camera raw files in JPEG (Joint Photographic Experts Group) format. To specify the

amount 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, slideshows, presentations, and
other online services.

TIFF

Saves copies of the camera raw files as TIFF (Tagged-Image File Format) files. Specify whether to apply no

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.

Photoshop

Saves copies of the camera raw files in the PSD file format. You can specify whether to preserve cropped

pixel data in the PSD file.

Making color and tonal adjustments in Camera Raw

Using 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 Raw” on page 94.
