Color Space - Canon 1236B001 - EOS Digital Rebel XTi Camera SLR Instruction Manual

Color space

A color space is the reproducible color range (color gamut
characteristics). DPP supports the following five kinds of color space.
sRGB : Standard color space for Windows. Widely used for the
standard color space of monitors, digital cameras, and
scanners.
Adobe RGB : A wider color space than sRGB. Mainly used for printing
for business purposes.
Apple RGB : Standard color space for Macintosh. A slightly wider color
space than sRGB.
ColorMatch RGB : A slightly wider color space than sRGB. Mainly
used for printing for business purposes.
Wide Gamut RGB : A wider color space than Adobe RGB.
Refer to the color chart below for the color area of each color space.

CMYK simulation profiles
A CMYK simulation profile is a profile for simulating colors in a CMYK
environment on printers etc. With DPP, you can simulate color with four
types of profile.
Euro Standard : Profile normally used for book printing in
Europe, suitable for simulation of standard
European printing.
JMPA : Profile normally used for book printing, etc. in
Japan, suitable for simulation of magazine
advertising standard color printing.
U.S.Web Coated : Profile normally used for book printing in
North America, suitable for simulation of
North American standard printing.
JapanColor2001 type3 : Profile becoming a standard in the Japanese
printing industry, suitable for simulation of
JapanColor standard printing.
Rendering intent
Rendering intents are color conversion methods when printing an image.
The conversion method of each rendering intent is shown below.
Perceptual : Before and after conversion, all colors are
converted to maintain the relationship between
colors. Even where colors slightly change, you
can print a natural-looking image which has
maintained color harmony. However,
depending on the image, the saturation may
change overall.
Relative Colorimetric : There will not be much conversion to colors
which are similar before and after conversion,
but colors which are not similar are converted
appropriately. Because there are little changes
to similar colors which comprise most of an
image, you can print a natural-looking image in
which the degree of color has not changed
greatly. However, depending on the image,
there are cases where the overall tone of an
image changes somewhat as colors which are
not similar and highlights change.
