Importing camera raw files

About camera raw files

A camera raw file contains unprocessed picture data from a digital camera's image sensor. Many digital cameras can
save image files in camera raw format. In this way, photographers can interpret the image data rather than having
the camera make the adjustments and conversions automatically.
Camera raw images contain the actual data captured by the sensor without any in-camera processing; these are the
only files containing "pure" data. Working with camera raw files gives you maximum control; you can set the white
balance, tonal range, contrast, color saturation, and sharpening. Think of camera raw files as your photo negative.
You can reprocess the file at any time to achieve the results you want.
When you open a camera raw image file, you can quickly apply adjustments, such as exposure compensation or tonal
adjustments, without compressing the image or losing any of the original image data (when you make adjustments
to a camera raw image file, the original camera raw file data is preserved). You can also make adjustments to the
camera raw file after you import it. In After Effects, camera raw converts to 8 or 16 bits per channel based on the
After Effects project setting.
Note: Camera raw files are uncompressed. Their large size may increase rendering time.

To work with the Camera Raw cache in Bridge

You can use Adobe Bridge to preview camera raw images using the default image settings and to apply settings
without opening the Camera Raw dialog box. You can also copy and paste the settings from one camera raw image
to another in Bridge.
When you view camera raw files in Bridge, the thumbnails and previews use either the camera raw 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.
The Camera Raw cache speeds loading of the Camera Raw dialog box and the recalculation of preview in Bridge after
changes are made to the Camera Raw settings. The Camera Raw cache holds preparsed raw image data for the most
recently accessed camera raw files.
Because the 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.
In Bridge, choose one of the following:
1
•
(Windows) Edit > Camera Raw Preferences.
•
(Mac OS) Bridge > Camera Raw Preferences.
2 Do any of the following, and click OK:
•
To change the cache size, type a value in the Maximum Size box.
•
To purge the Camera Raw cache, click the Purge Cache button.
