highlights appear in red. Highlight clipping is shown if any one of the three RGB channels is clipped (fully saturated
with no detail). Shadow clipping is shown if all three RGB channels are clipped (black with no detail).

Work with the Camera Raw cache in Bridge
When you view camera raw files in Adobe Bridge, the thumbnails and previews use either the default settings or your
adjusted settings. The cache in Bridge and the Camera Raw cache store data for the file thumbnails, metadata, and
file information. Caching this data shortens the loading time when you return to a previously viewed folder.
Because caches can become very large, you may want to purge the cache or limit its size. You can also purge and
regenerate the cache if you suspect that it is corrupted or old. Purging the cache deletes thumbnail information and
metadata added since the camera raw file was opened in Bridge.
Note: The Camera Raw cache holds data for about 200 images for each gigabyte of disk storage allocated to it. By default,
the Camera Raw cache is set to a maximum size of 1 GB. You can increase its limit in the Camera Raw preferences.
1 In Bridge, choose Edit > Camera Raw Preferences (Windows) or Bridge > Camera Raw Preferences (Mac OS), or,
with the Camera Raw dialog box open, click the Open Preferences Dialog button .
2 Do any of the following:
• To change the cache size, enter a Maximum Size value.
• To purge the camera raw cache, click the Purge Cache button.
• To change the location of the camera raw cache, click Select Location.
Navigating, opening, and saving images
Process, compare, and rate multiple images in Camera Raw
The most convenient way to work with multiple camera raw images is to use the Filmstrip view in Camera Raw,
which opens by default when you open multiple images in Camera Raw from Bridge.
Images can have three states in Filmstrip view: deselected, selected (but not active), and active (also selected). In
general, adjustments are applied to all selected images.
