Technical Information
4) Processing parameters
(1) Color shooting
The EOS 20D now has the same "Parameter 1" as the EOS DIGITAL
REBEL/EOS 300D DIGITAL to obtain vivid and sharp images. "Parameter 2"
is the same as the EOS 10D's "Standard" setting.
In the Basic Zone modes, "Parameter 1" is set automatically. In the Creative
Zone modes, you can select "Parameter 1 or 2", "Set 1 to 3", or "B/W".
Compared with the EOS 10D, the "Saturation" is "+1" to obtain slightly
higher saturation. Also, the "Sharpness" settings of "+1" and "+2" are now
twice as strong as the EOS 10D's.
(2) Monochrome
The camera's internal digital processing
enables black-and-white images to be produced.
When "B/W" is selected, you can freely set the
"Contrast," "Sharpness," "Filter effects," and
"Toning Effect" parameters.
The "Contrast" and "Sharpness" provides five
settings as with color shooting.
"Filter effects" is the equivalent of using color
filters to adjust the contrast of B/W photos shot
with film. Through digital processing, the colors in the image matching the
selected filter's color (yellow, orange, red, or green) will look brighter, and the
complementary colors in the hue circle will look darker.
"Toning Effect" adds a color cast (sepia, blue, purple, or green) to the black-
and-white image. It is akin to using chemicals to tone a black-and-white,
silver-halide print. "Toning Effect" is the digital version of this process.
Note 1: When "Filter effects" is set and "Contrast" is set to the plus side, the effect will be more
pronounced.
Note 2: Due to slight differences in the spectral characteristics between the EOS 20D's CMOS
sensor and B/W film covered with a color filter, "Filter effects" might not give the same
result as when you use B/W film with a color filter.
