Raw Images - Canon EOS 70D Instruction Manual

3 Setting the Image-Recording Quality
If you select both RAW and JPEG, the same image will be recorded
simultaneously to the card in both RAW and JPEG at the image-
recording qualities that were set. The two images will be recorded with
the same file numbers (file extension: .JPG for JPEG and .CR2 for
RAW).
The image-recording quality icons are as follows: 1 (RAW), 41
(Middle RAW), 61 (Small RAW), JPEG, 7 (Fine), 8 (Normal), 3
(Large), 4 (Middle), 6 (Small).

RAW Images

A RAW image is raw data output by the image sensor converted to
digital data. It is recorded to the card as is, and you can select the
quality as follows: 1, 41, or 61.
A 1 image can be processed with [31: RAW image processing]
(p.328) and saved as a JPEG image. (41 and 61 images cannot
be processed with the camera.) While the RAW image itself does not
change, you can process the RAW image according to different
conditions to create any number of JPEG images from it.
With all RAW images, you can use Digital Photo Professional (provided
software, p.456) to make various adjustments and then generate a
JPEG, TIFF, etc., image incorporating those adjustments.
To display RAW images on a computer, using the provided software is
recommended (p.456).
Commercially-available software may not be able to display RAW
images taken by the camera. For details on commercially-available
software, contact the software manufacturer.
