CS4 14Bit

[ja...@uvvm.uvic.ca]

I have a Nikon d300 camera that can be set for 12 or 14 bit images.
After I bring a 14 bit image into CS4 I look at :image :mode: and see
:8bit channel. What hapened to the other 6bit? Why don't I have the
16bit channel?

jpegs are converted to 8 bit in the camera. If you want 16 bits, set your
camera to RAW format, and use Bridge (or Camera Raw directly in Photoshop)
to access the image in 16 bit mode in Photoshop.

You need to shoot raw (or raw+JPG) and open the raw version. In
photoshop, it will initially open in a raw import tool called "Camera Raw".

You can do a substantial amount of "pre-edit" in Camera Raw. Adjusting
for light source, for underexposure, some amount of over exposure,
setting the black point, contrast, brightness, etc. etc., correct for
distortion, lens chromatic aberration, sharpness, color space, and more.

When you open the image from Camera Raw it's then imported into CS4.

Using a program like Bridge (included with CS4) you can select many
images, double click, and all will go to Camera raw. If the pre-edit
adjustments are the same, you can apply them to all the images you
selected in one go - can save a lot of labour...

If you open a NEF image in Photoshop, the CameraRAW dialog is invoked.
At the bottom of that dialog, you'll see something that looks like a
link in a web browser. Click on it to get to the Camera RAW preferences.
There you can set that the resulting image is opened in Photoshop as 8
bits or as 16 bits image.

If you shoot JPEG then the answer is simple: JPEG only spports 8 bits.
