Posłużę się jeszcze cytatem z pewnej fajnej książki :
"Real World Camera Raw with Adobe Photoshop CS2 Industrial-Strength Production Techniques"
By Bruce Fraser

"The High-Bit Advantage
Any camera that shoots raw captures at least 10 bits per pixel, offering a possible 1,024 tonal values, while most capture 12 bits for 4,096 levels, and a few capture 14 bits, for 16,384 possible tonal values. An 8-bit/channel image allows only 256 possible tonal values in each channel, so when you convert a raw image to an 8-bit/channel file, you're throwing away a great deal of potentially useful data.

The downsides of 16-bit/channel images are that they take up twice as much storage space (on disk and in RAM) as 8-bit/channel ones, and an ever-shrinking list of Photoshop features don't work in 16-bit/channel mode. The advantage is that they offer massively more editing headroom.

If you're preparing images for the Web or you need to use a Photoshop feature such as Liquify that only works in 8-bit/channel mode, by all means go ahead and process the raw images to 8-bit channel files. In just about every other scenario, I recommend processing to a 16-bit/channel file. Even if you think the image will require little or no editing in Photoshop, it's likely that at some point the image will have to undergo a color space conversion for output, and making that conversion on a 16-bit/channel image can often avoid problems such as banding in skies or posterization in shadows that suddenly appear after an 8-bit/channel conversion."
