clipped (black with no detail).

Work with the Camera Raw cache in Adobe Bridge
When you view camera raw files in Adobe Bridge, the thumbnails and previews use either the default settings or your
adjusted settings. The Adobe Bridge cache stores data for the file thumbnails, metadata, and file information. Caching
this data shortens the loading time when you return to a previously viewed folder in Adobe Bridge. The Camera Raw
cache speeds the opening of images in Camera Raw and rebuilds of previews in Adobe Bridge when image settings
change in Camera Raw.
Because caches can become very large, you may want to purge the Camera Raw cache or limit its size. You can also
purge and regenerate the cache if you suspect that it is corrupted or old.
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 Adobe 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.
