• White balance bracketing (WB-BKT)
In addition to the EOS 10D's blue/amber bias correction, the EOS 20D
provides the magenta/green bias adjustment that works like a cc (color
compensating) filter. As with the EOS 10D, three images are generated with
one shot. WB-BKT can also be used in combination with white balance
correction.
• Auto/Preset white balance
With DIGIC II, AWB is more stable at high ISO speeds and the color
temperature information is sent when the built-in flash or SL580EX is fired.
As a result, the flash white balance and AWB performance with flash in
dark environments are improved.
(2) Processing parameters
• Parameter 1 for vivid and sharp images
In addition to the EOS DIGITAL REBEL/EOS
300D DIGITAL's Parameter 1, the EOS 20D also
has the Parameter 2 which is the EOS 10D's
standard setting. Parameter 1 is set
automatically in Basic Zone modes. In Creative
Zone modes, Parameter 1 or 2 can be selected.
• Monochrome mode
In addition to Parameter 1 and 2 and Set 1, 2,
and 3, there is a new Monochrome mode. You
can set the contrast and sharpness up to 5
levels, filter effects (none, yellow, orange, red,
green), and toning (none, sepia, blue, purple,
green).
<Filter effects>
This obtains almost the same result
as filters for conventional black-and-
white photos. The colors in the image
that are the same or similar to the
filter's color will look brighter. And
secondary colors in the hue circle will
look darker.
<Toning>
This is like toning conventional
black-and-white prints with chemicals
to apply a certain color tinge. This is
done digitally to obtain a similar effect.
