Image-Recording Quality; White Balance; Long Exposure Noise Reduction - Canon EOS 5D Service Manual

３）Image-recording quality
Table 003 shows the correlation between the recording quality and file size.
Specifications for RAW+JPEG simultaneous recording, color space (sRGB/Adobe RGB) RAW,
Design rule for Camera File System, Exif, etc., are the same as the EOS 20D's.

＊The number of possible shots apply to a Canon 512MB CF card.
＊ The single image size and number of possible shots will vary depending on the subject, shooting mode, Picture Style, ISO
speed, etc.
４）White balance
Specifications for the auto white balance, white
balance correction, and white balance bracketing are
the same as the EOS 20D's.
５）Long exposure noise reduction
C.Fn-2 for noise reduction of long exposures can be
set to "Off" or "Auto noise reduction" or "On."
［Auto noise reduction］
For long exposures 1 sec. or longer, noise caused by a long exposure or high temperature
(spotty noise or reddish corners) is detected. If it is determined to be noise, noise reduction
is performed. Normally, this setting is most effective.
［On］
For long exposures 1 sec. or longer, noise reduction is always performed. This setting is
effective for reducing noise generated (rarely) in low temperatures that cannot be detected
automatically.
Note: With the "Auto noise reduction" and "On" setting, noise reduction will be performed according to the two
conditions above regardless of the ISO speed.
Like the EOS-1Ds Mark II, the EOS 5D enables continuous shooting even while noise
reduction is performed as long as the buffer memory is free. Also, when shutter speed-
priority AE or manual exposure is set and continuous shooting is done at the same shutter
speed, noise reduction will be performed in a single process on all the shots based on the
first shot.
