Select this format to process images on a computer for professional purposes. • The image size is fixed to the maximum size. The image size is not displayed on the LCD monitor. RAW & JPEG ( ) cRAW & JPEG* ( ) Extra fine ( ) Fine ( ) Standard ( ) File format: RAW (raw data) + JPEG A RAW image and a JPEG image are created at the same time. This is suitable when you need two image files, a JPEG for viewing, and a RAW for editing. The image quality is fixed to [Fine]. File format: JPEG The image is compressed in the JPEG format when recorded. The higher the compression rate, the smaller the file size. This will allow more files to be recorded in one memory card, but the image quality will be lower. * "c" of "cRAW" means "compressed." The data is compressed up to about 60 to 70% compared to an image not compressed. Use this setting when you want to increase the number of images that can be taken. Note • For details on the number of images that can be taken when the image quality is changed, see page 33.
