Canon EOS 20D Digital, Service Manual

Page: 77 / 374

(3) New RAW format
The EOS 20D incorporates the same new RAW format featured in Canon
digital cameras from the EOS-1D Mark II onward. The file extension is .CR2
(Canon Raw 2nd edition). The RAW data records the white balance (preset,
correction, bracketing information), processing parameters, and other
settings. When you use a personal computer to edit the image, all these
settings will take effect. (Since it is raw data, you can edit the image freely
with image-editing software.)
(4) DCF Version 2.0 / Exif Version 2.21
The camera complies to DCF 2.0 (revised to support Adobe RGB) and Exif
2.21. Images taken in Adobe RGB will have the Adobe RGB color space
information (not ICC profile) appended to the Exif information. Therefore,
applications and devices compatible with DCF 2.0 and Exif 2.21 will be able
to handle Adobe RGB in the same way as sRGB. You need not worry about
the color space anymore.
Note that the file name of images taken with Adobe RGB will start with an
underbar (_) as required by DCF 2.0 and Exif 2.21.
Note: Although RAW does not comply to DCF, the file name will start with an underbar as with
JPEG images. When you use the provided software to edit the RAW image and save it as a
JPEG or TIFF file, the Adobe RGB profile will be appended to the image.
3) Color space
With the [Color space] menu, you can select [sRGB] or [Adobe RGB]. With the
EOS 10D, if you selected Adobe RGB, the processing parameter would be set
automatically to Standard (all items set to 0). But with the EOS 20D, even if you
select Adobe RGB, you can still shoot with any processing parameter.
