60Changing the File FormatThe recording file format can be switched to the RAW format beforeshooting the image.With the standard JPEG file format, the camera processes imagesafter capturing them to produce optimal results. The JPEG formatcompresses images so that more can be stored on a single CF card.However, the compression is irreversible, meaning that the originalimage data cannot be recovered after processing.In contrast, the RAW format records the image data as captured bythe camera’s CCD without further processing. RAW images arecompressed, but the compression is reversible* so that a high-quality image can be obtained from the decompressed file withoutany loss of image quality. In addition, although a RAW file is largerthan an equivalent JPEG file, it is still only approximately one-quarter the size* of an uncompressed RGB TIFF format file, makingit relatively compact.With standard uncompressed file formats, such as RGB TIFF,images are processed in the camera and require further processingby retouching software to adjust the image parameters, whichreduces image quality. With the RAW format, however, the originaldata can be used in special software** to adjust the imageparameters (white balance, contrast, sharpness and saturation)making it possible to maintain the image quality while makingchanges. The resolution (3264 x 2448) and compression settingscannot be adjusted for these images.* As measured by Canon’s testing standard.** The bundled software can be used to open or adjust the parameters ofimages recorded in the RAW file format.
