A Camera Raw file is the unprocessed image data from a digital camera's image sensor, along with information capture information (time, f/stop/ shutter speed, white balance, etc.). Photoshop Camera Raw is Adobe's software that is used to look at the camera raw file and to use the image's metadata to process the image. The camera raw file is like a photo negative. You can reprocess it at any time, getting different results by making adjustments for white balance, color saturation, tonal range, sharpening, contrast, etc.. When you adjust a camera raw image, the original camera raw data is preserved. Adjustments are stored as metadata in an accompanying file (called a side-car), usually in in a database folder in Photoshop.
