Stage 2B: Processing RAW Images

Many higher end digital cameras create RAW files. Each digital camera has its own RAW file format and file extension: Canon RAW files are called CRW files, Nikon files NEF, etc. RAW file images contain all the original data captured by the digital camera sensor. Working from this original data, the RAW file can produce a higher quality image than that created in a Jpeg image. The main advantage of RAW files is their inclusion of data for 16 bits per channel images and less susceptibility to image degradation under significant edit. One disadvantage is RAW files are much larger than Jpeg files, so you can store far fewer RAW images in your camera. And only a few applications, Adobe Photoshop CS2 and Adobe Bridge among them, can view them.

That said, it's best to capture digital camera images using RAW files. If you are new to digital imaging, capture your images as Jpeg files until you feel comfortable with the overall process. When you're ready, configure your digital camera to include capturing image as RAW files.

Open RAW files the same as other types of image files, by double-clicking on an image in Bridge or by navigating through the File Open dialog within Photoshop. When an RAW file opens, Photoshop displays the Adobe Camera RAW dialog.
