Adobe Photoshop CS5 One-on-One

Captured with a Canon EOS 5D and converted from the CR2

format to DNG, each of these 12-megapixel photos weighs in at

around 10MB, or somewhere between two and four times the

size of an equivalent image saved as a high-quality JPEG file.

The theoretical color range includes more than a billion pos-

sible variations, 64 times as many as a JPEG image. To distill

these billion or so colors to the best 16 million (as explained in

the sidebar, “Exploring High Bit Depths” on page 302), the Bridge

requires the image to pass through the Camera Raw plug-in.

2. Open the images in Camera Raw. From the Bridge, you get to
   Camera Raw in one of two ways:
   
   
   • Choose File→Open or double-click any one of the selected
     thumbnails to switch to Photoshop and display the Cam-
     era Raw interface.
   
   
   • Choose File→Open in Camera Raw or press Ctrl+R (�-R)
     to load the Camera Raw interface directly inside the Bridge.
     Although either method is fine, the latter is a bit more flexible,
     permitting you to examine one or more raw photos while keep-
     ing Photoshop free to perform more complex modifications.
     So choose File→Open in Camera Raw as you see me doing in
     Figure 9-5 or press Ctrl+R (�-R) to display Camera Raw in the
     Bridge. As witnessed in Figure 9-6 on the facing page, Camera
     Raw includes a high-resolution preview of the selected image,
     a vertical filmstrip of thumbnails (visible only when adjusting
     multiple images), and a full-color histogram, all of which update
     as you adjust the color settings. The title bar lists the model of
     camera used to shoot the photo.
   
   
   
   

If you want to devote 100 percent of your attention to Camera Raw,

you can fill the screen with the interface by clicking the icon to the

left of the histogram or by pressing the F key.

Directly below the histogram, you’ll see the ISO, exposure, ap-

erture, and shutter speed. This EXIF data helps Camera Raw

establish some of its automatic settings.

Below the EXIF data is a panel that contains the Camera Raw

controls for developing your images. The contents of this panel

change depending on which tab you have selected from the

ten displayed directly above the panel. Camera Raw opens by

default to the Basic tab, which contains the most essential and

often-used adjustment tools.
