RAW Format

There are two common file formats for digital camera, JPG (JPEG, normally 8 bits per channel) and RAW (at least 12 bits). JPG is the industry standard for web design (compressed, small file size). RAW records the unprocessed sensor data. Besides to ISO, shutter speed and aperture, everything else is under your control during the conversion process. Such as, temperature, tint, exposure, shadows, brightness, contrast and saturation. Adobe Photoshop CS2 can correct chromatic aberration and vignetting too.

Tips: Take the advantage for the extra stops in RAW to merge multi-layers from different processes.

Tricks: More colors are available from the slightly underexposed image.
