PHOTOSHOP CS3 86 User Guide Using Bridge, you can apply, copy, and clear image settings, and you can see previews and metadata for camera raw files without opening them in the Camera Raw dialog box. The preview in Bridge is a JPEG image generated using the current image settings; the preview is not the raw camera data itself, which would appear as a very dark grayscale image. Note: A caution icon appears in the thumbnails and preview image in the Camera Raw dialog box while the preview is generated from the camera raw image. You can modify the default settings that Camera Raw uses for a particular model of camera. For each camera model, you can also modify the defaults for a particular ISO setting or a particular camera (by serial number). You can modify and save image settings as presets for use with other images. When you use Camera Raw to make adjustments (including straightening and cropping) to a camera raw image, the image's original camera raw data is preserved. The adjustments are stored for each image in either the Camera Raw database, as metadata embedded in the image file, or in a sidecar XMP file (a metadata file that accompanies a camera raw file). For more information, see "Specify where Camera Raw settings are stored" on page 104. After you process and edit a camera raw file using the Camera Raw plug-in, an icon appears in the image thumbnail in Bridge. If you open a camera raw file in Photoshop, you can save the image in other image formats, such as PSD, JPEG, Large Document Format (PSB), TIFF, Cineon, Photoshop Raw, PNG, or PBM. From the Camera Raw dialog box in Photoshop, you can save the processed files in Digital Negative (DNG), JPEG, TIFF, or Photoshop (PSD) formats. Although Photoshop Camera Raw software can open and edit a camera raw image file, it cannot save an image in a camera raw format. Note: In Photoshop, the Camera Raw dialog box is automatically suppressed when you use a batch of files for a web photo gallery, picture package, or contact sheet. As new versions of Camera Raw become available, you can update this software by installing a new version of the plug-in. You can check for updates to Adobe software by choosing Help > Updates. For up-to-date documentation for Camera Raw, go to the Adobe website at www.adobe.com/go/learn_ps_camerarawhelp. Different camera models save camera raw images in many different formats, and the data must be interpreted differently for these formats. Camera Raw includes profiles for many camera models, and it can interpret many camera raw formats. Note: For a list of supported cameras and for more information about Camera Raw, see www.adobe.com/go/learn_ps_cameraraw. About the Digital Negative (DNG) format The Digital Negative (DNG) format is a non-proprietary, publicly documented, and widely supported format for storing raw camera data. Hardware and software developers use DNG because it results in a flexible workflow for processing and archiving camera raw data. You may also use DNG as an intermediate format for storing images that were originally captured using a proprietary camera raw format. Because DNG metadata is publicly documented, software readers such as Camera Raw do not need camera-specific knowledge to decode and process files created by a camera that supports DNG. If support for a proprietary format is discontinued, users may not be able to access images stored in that format, and the images may be lost forever. Because DNG is publicly documented, it is far more likely that raw images stored as DNG files will be readable by software in the distant future, making DNG a safer choice for archival storage.
