Note
The Photoshop Raw format (.raw extension) is a file format for
transferring images between applications and computer plat-
forms. Don't confuse Photoshop Raw with camera raw
file formats.
To create camera raw files, set your digital camera to save files in its own, possibly
proprietary, raw file format. When you download the file from your camera, it has
a file extension such as .nef (from Nikon) or .crw (from Canon). In Bridge or Pho-
toshop, you can process camera raw files from a myriad of supported digital cam-
eras from Canon, Kodak, Leica, Nikon, and other makers—and even process mul-
tiple images simultaneously. You can then export the proprietary camera raw files
to DNG, JPEG, TIFF, or PSD file format.
You can process camera raw files obtained from supported cameras, but you can
also open TIFF and JPEG images in Camera Raw, which includes some editing
features that aren't in Photoshop. However, you won't have the same flexibility
with white balance and other settings if you're using a TIFF or JPEG image. Al-
though Camera Raw can open and edit a camera raw image file, it cannot save an
image in camera raw format.
Processing files in Camera Raw
When you make adjustments to an image in Camera Raw, such as straightening
or cropping the image, Photoshop and Bridge preserve the original file data. This
way, you can edit the image as you desire, export the edited image, and keep the
original intact for future use or other adjustments.
Opening images in Camera Raw
You can open Camera Raw from either Bridge or Photoshop, and you can apply
the same edits to multiple files simultaneously. This is especially useful if you're
working with images that were all shot in the same environment, and which there-
fore need the same lighting and other adjustments.
Camera Raw provides extensive controls for adjusting white balance, exposure,
contrast, sharpness, tone curves, and much more. In this exercise, you'll edit one
image and then apply the settings to similar images.
