79 Converting RAW Format Images Please check whether or not your camera model supports this function (p. 12). The RAW image file format records image data as captured by the camera's image sensor without further processing by the camera. Although the data is compressed when recorded, the original data can be completely restored without any loss of quality. Moreover, the RAW format is extremely compact, creating files approximately onequarter the size* of uncompressed files (RGB TIFF). However, RAW images cannot be opened by standard image editing programs unless they are first converted. Conversion involves generating high-quality RGB signals from the RAW format files. If you start File Viewer Utility from ImageBrowser, you can adjust the attributes of the original data before conversion to retain the degree of image quality appropriate to your purposes. The result is high-quality images. In contrast, image data recorded in the RGB TIFF and other standard uncompressed file formats is irrevocably processed in the camera and again by an application program when you change the file attributes, which reduces the image quality. * As measured by standard Canon test conditions. • Please see the Camera User Guide to learn how to shoot RAW images.

Converting RAW Format Images
Please check whether or not your camera model supports this function (p. 12).
The RAW image file format records image data as captured by the camera’s image
sensor without further processing by the camera. Although the data is compressed
when recorded, the original data can be completely restored without any loss of quality.
Moreover, the RAW format is extremely compact, creating files approximately one-
quarter the size* of uncompressed files (RGB TIFF). However, RAW images cannot be
opened by standard image editing programs unless they are first converted.
Conversion involves generating high-quality RGB signals from the RAW format files.
If you start File Viewer Utility from ImageBrowser, you can adjust the attributes of the
original data before conversion to retain the degree of image quality appropriate to
your purposes. The result is high-quality images. In contrast, image data recorded in
the RGB TIFF and other standard uncompressed file formats is irrevocably processed in
the camera and again by an application program when you change the file attributes,
which reduces the image quality.
