Tip: when Camera Raw opens it will immediately begin the
process of building the high resolution preview images. Fortunately, it
does so on-the-fly, but be aware that takes it time to generate these
previews. The yellow alert icon that appears on the top right of an
image signifies that the high resolution preview is being generated.
When you select an image Camera Raw gives it priority and the preview
will usually be fully generated within a second or two. Usually this
means that the image initially appears soft, almost like it's out of
focus, but then it quickly snaps into focus.

Step 3 - Configuring Camera Raw for 100%
Previews
Whilst the objective of this tutorial is to demonstrate how Camera Raw
can be used for 100% previews it's also important that it does so in an
efficient manner. For example, simply selecting each image from the
filmstrip and hitting the Ctrl/Cmd+Option+0 keys to zoom it to100%
will drive you nuts, especially when you're trying to preview lots of
images. The most efficient method is to choose Select All
using either the button or Ctrl/Cmd+A.

Figure 5 - Camera Raw 100% View
With all of the images now selected you can choose 100%
from the magnification pop-up (Figure 5, red circle) or better still use
the Ctrl/Cmd+Option+0 keys. Either way will have the same effect,
in so far as Camera Raw is now configured to show each image at 100%.
Next hit the Shift+Ctrl/Cmd+A keys to deselect the images.
Ste 4 - Previewing the Images
Previewing the images at 100% is now as simple as
"clicking" on them or using the "down-arrow" key. If you
hold the Spacebar key down the Hand Tool
appears, which allows you scroll the image in any direction using the
"mouse".
-
To rate an image hit the Ctrl/Cmd+1 through 5
keys.
-
To label an image hit the Ctrl/Cmd+6 through 0
keys.
-
To mark an image for deletion hit the Delete
key, a large red X will appear in the top left corner of the thumbnail.
Note: The numeric keypad (right side of
keyboard) cannot be used to apply labels or ratings with Camera Raw.
Tip: When working in Camera Raw film-strip mode
you might find that after
adjusting an image the keystrokes for Next (Down-arrow key) and
Previous (Up-arrow key) image no longer function... frustrating isn't
it? The normal solution is to use the mouse to click the little triangle
buttons found at the bottom right corner of the image preview window. However, there is a much faster
method that doesn't involve the mouse, i.e. Next image ~ Cmd/Ctrl+Right-arrow
key and Previous image ~ Cmd/Ctrl+Left-arrow key.

Figure 6 - Ratings, Labels and Marked for Deletion
Once you've completed your review of the images simply click the
Done button and return to the Bridge. In Bridge you should
find that all of the previews reflect any rating and/or labelling applied
in Camera Raw. Images that were marked for deletion in Camera Raw should
already have been deleted. Now wasn't that simple!
As Bruce Fraser says: "I agree that a loupe tool in
Bridge would be a better long-term solution, but it WILL be a long-term
solution. This way isn't all bad once you get used to it. (Command-A,
Command-R, Command-A, Command-Option-zero, then down arrow to go through
the images.)". Bruce is the author of a very useful book called
Real World Camera Raw with Photoshop CS2. If you're interested in
getting to know the true power of Bridge and Camera Raw, then I recommend
that you obtain a copy.
