• JPEG Images ( )
When JPEG images are recorded, the images are processed inside the camera for
optimum image quality, and also compressed to allow a larger number of images to
be stored on the memory card. However, the compression process is irreversible,
meaning that the raw data cannot be recovered once it has been compressed.
Moreover, the image processing results in a deterioration in quality.
• RAW Images ( )
A RAW image is raw data recorded with nearly no deterioration in image quality
resulting from image processing inside the camera. This data cannot be used as is for
viewing or printing on a computer. The supplied software (Digital Photo Professional)
must first be used to convert the image data to a JPEG or TIFF file. When converting
the image data, you can adjust the image with minimal deterioration in image quality.
Simultaneously Recording RAW and JPEG Images
Two images, a RAW image and a JPEG image will be recorded with each shot.
Since a JPEG image is also recorded, you can print the image or view it on a
computer without using the supplied software.
The file extension for RAW images is ".CR2", and the extension for JPEG
images is ".JPG". The JPEG images will be recorded with
recording
pixels with image compression.
