About camera raw files
A
camera raw
file contains unprocessed picture data from a digital camera's image
sensor. Many digital cameras can save images in camera raw format. The advant-
age of camera raw files is that they let the photographer—rather than the cam-
era—interpret the image data and make adjustments and conversions. (In contrast,
shooting JPEG images with your camera locks the camera's processing into the
image.) Because the camera doesn't do any image processing when you shoot
a camera raw photo, you can use Adobe Camera Raw to set the white balance,
tonal range, contrast, color saturation, and sharpening. Think of camera raw files
as photo negatives: You can go back and reprocess the file any time you like to
achieve the results you want.
