Setting The Image-Recording Quality; Selecting The Image Size - Canon EOS 1Ds Mark III Instruction Manual

Setting the Image-recording Quality

You can set the image size (recorded pixels), image type (JPEG, RAW,
sRAW), and JPEG quality (compression rate).

Selecting the Image Size

3/4/5/6 will record the image in the JPEG. In the 1/9 mode,
the image will require processing with the software provided. 9 is a
small RAW image which is one-fourth (approx. 5.2 megapixels) the size
of a normal RAW image.
Also, RAW/sRAW and JPEG images can be recorded at the same time
on the memory card.
