Keeping Colors True

Turning Nikon CMS Off

CMYK

The Nikon Color Management System, or Nikon CMS, en­ sures that image data from Nikon scanners are re pro duced
consistently and accurately on monitors or print ers. With this
pow er ful tool, colors can be manipulated in a cal i brat ed RGB
color model before the data are passed to the host applica­tion. Profi les detailing the color char ac ter is tics of the chosen
color model and the output de vice (mon i tor or print er) en­sure that colors will be reproduced ac cu rate ly in al most any
operating environment.

Keeping Colors True

Nikon CMS involves two categories of preferences, one
(“Gamma”) for use when Nikon CMS is off and the other
(“Color Man age ment”) for use when Nikon CMS is on.
“Gamma” specifi es how data from the scanner will be mod­ i fi ed for display on the monitor. Because monitor profi les
can not be used when Nikon CMS is off, this adjustment
must be made manually. “Color Management” is used to
turn Nikon CMS on and off and select the profi les for use
with the monitor and with the CMYK and calibrated RGB
color models when Nikon CMS is on.

Tur ning Nikon CMS Off

In general, much better results can be achieved with Nikon CMS on. It
may however be necessary to turn color management off to:

CMYK

Images can not be scanned in CMYK. If CMYK data are required, con­vert images to CMYK before saving them to disk. Note that images
can only be saved in CMYK if Nikon CMS is on (Nikon CMS is on by
default).

Preferences— Nikon Color Management

• Speed processing

If the computer has a slow CPU, the processing required for color
management may result in longer scan times. Try turning color man­agement off for reduced scan times.

• Edit data from the scanner directly

Advanced users may want to turn Nikon CMS off to edit uncalibrated
RGB data from the scanner.

How Nikon CMS Works

Creating Monitor Profi les

When image data are passed from an input device, such as
a scanner, to an output device, such as a monitor or printer,
color management ensures that the image displayed on the
output device “looks the same” as the original. To accom­plish this task, the color management system must have
information about the color characteristics of both the input
and output devices, as well as the color space used for edit­ing. The fi les containing this in for ma tion are called “ICC pro­fi les.” Nikon Scan uses the fol low ing three types of profi le:

Input Profi les

Input profi les provide information on the input device, i.e.,
the Nikon scanner. Fixed pro fi les de tail ing the color char­ ac ter is tics of sup port ed Nikon scanners are provided with
Nikon Scan. An input profi le is se lect ed au to mat i cal ly based
on the model of scan ner used and the type of media (pos­ i tive or negative) being scanned.

Color-Space Profi les

Separate profi les are avail able for the RGB and CMYK color
models. Nikon Scan comes with a selection of profi les for
the RGB color model, while CMYK profi les for color print ers
are usually pro vid ed by the man u fac tur er. Color-space pro­ fi les are used when editing images in the scan win dow and
when making the fi nal scan.

Monitor Profi les

Monitor profi les are usually provided by the manufacturer,
although profi les for some common monitor types may be
included with the computer operating system. Monitor
profi les apply when images are displayed on a monitor, for
example when an image is displayed in the preview area or
an image win dow.

Preferences— Nikon Color Management

Creating Monitor Profi les

If desired, Adobe Photoshop can be used to create a monitor profi le for
a specifi c environment. This profi le can then be used in Nikon Scan.
For information on creating monitor profi les, see the doc u men ta tion
provided with Adobe Photoshop. This option is not avail able in Adobe
Photoshop LE.

The Scanning Process

The illustration below shows the role Nikon CMS plays in
the scanning process. CMS profi les are shown in blue, user
op er a tions in red.

When Nikon CMS is on, uncalibrated RGB image data from
the scan ner are converted to grayscale or calibrated RGB,
de pend ing on the color model selected in the scan window.
RGB data are processed according to the profi le selected for
the calibrated RGB color space. These data are stored in
mem o ry so that the color model can be changed with out
per form ing an oth er pre view. Any changes made using the
color enhancement and Unsharp Mask tools also ap ply to
these data. When the im age is dis played in the pre view win­ dow, the mon i tor pro fi le is used to ensure that the preview
image is as true as pos si ble to the data in mem o ry.

When the Scan button is clicked to perform the fi nal scan,
the scan data are processed according to the selected color­space profi le and any changes that were made using the
color en hance ment and Unsharp Mask tools in the scan
win dow. The data are then trans ferred to the host ap pli ­ca tion. Where pos si ble, the color-space pro fi le is trans ferred
to the host ap pli ca tion to geth er with the im age data. The
TWAIN in ter face used in Windows, how ev er, does not al low
profi les to be passed to an oth er ap pli ca tion, with the result
that under Win dows the pro fi le is only transferred to the
host when Nikon Scan is used as a “stand-alone” application
(note that profi le information is lost when the image is saved
in a format such as BMP that does not allow the profi le to
be recorded). When im ag es are dis played in im age win dows
in Nikon Scan, the monitor profi le en sures that the image on
the screen refl ects the orig i nal as close ly as pos si ble.

Scanning with Nikon CMS Off

If Use Nikon Color Management System is not selected in
the “Color Management” category, profi les can not be used
to ensure that the data from the scanner are reproduced ac­ cu rate ly when passed to another application or displayed in
the mon i tor. Be cause the color profi les required for a cal i ­brat ed RGB color space are not available when Nikon CMS is
off, images can only be scanned as uncalibrated RGB or gray­scale. Similarly, the absence of a monitor profi le means that
gamma adjustment must be used to correct the image for
dis play on the monitor or for editing in another application.
These ad just ments to gamma are made in the “Gamma”
category of the “Pref er enc es” dialog.

The illustration below shows how scanning proceeds when
Nikon CMS is off. The image shown in the preview window
is ad just ed for display in the monitor ac cord ing to the value
cho sen for preview gamma in the “Gam ma” category. When
the Scan but ton is clicked, the main scan gamma and any
changes to curves and color balance are passed to the scan­ ner, where they are ap plied to scan data be fore the image is
trans ferred to the host ap pli ca tion (if Nikon Scan is used as
a “stand-alone” ap pli ca tion, the value for preview gam ma
is passed to the scan ner instead of main scan gamma). The
LCH Editor and Unsharp Mask tools can not be used when
Nikon CMS is off.

Gamma

When the Use Nikon Color Management System option
in the “Color Management” category (

84) is off, the con-

trols in the “Gamma” category are used to adjust data from
the scanner so that they display correctly when previewed on
the monitor or opened in an oth er application.

Preview gamma

Preview gamma applies to the image displayed in the pre­ view area of the scan window. In general, preview gamma
is solely for display in the preview area and does not apply
to the image data that are passed to the host application
when the Scan button is clicked. There are two exceptions
to this rule, how ev er. The fi rst is when Nikon Scan is used as
a “stand-alone” application, the second when Use preview
gam ma is se lect ed as the main scan gamma option. In
these cases pre view gam ma is ap plied to im age data passed
to the host ap pli ca tion.

Preview gam ma de faults to a val ue of 1.8 on the Macintosh,

2.2 on Win dows com put ers. To choose a set ting suited to
the current monitor, adjust the value so that the pat terns of
gray lines and dots above the slider match in density. Gam­ ma can be set by en ter ing a value directly into the text box or
by moving the slider. When mak ing this ad just ment, set the
res o lu tion on the monitor to a low value such as 640 × 480
and sit as far away from the monitor as possible. To restore
the default setting for your platform, click Reset.

Main scan gamma

Main scan gamma options are only
visible when Nikon Scan is being
used as a TWAIN source or acquire
plug-in for an oth er program (when
Nikon Scan is used as a “stand­alone” application, preview gamma automatically applies
both to the preview image and to the fi nal scan). Image data
passed to the host application are modifi ed according to the
option chosen here. Three op tions are available:

Use preview gamma

The gamma value chosen for preview gamma is applied be­ fore the data are passed to the host application. Use this
setting when the host application does not support in de ­pen dent gam ma settings and you want the fi nal image to be
modifi ed for display on your monitor.

Use application gamma

In some environments, a value for gamma can be chosen
in the host application and passed to the Nikon Scan plug­in. When Use application gamma is selected, this value is
applied to the main scan data before they are passed to the
host application.

Two conditions must be fulfi lled if this option is to be ef fec ­tive. First, the in ter face be tween the ap pli ca tion and Nikon
Scan must allow the gamma value to be passed to the Nikon
Scan plug-in. The TWAIN in ter face used under Windows
does not, however, allow the gamma value to be passed to
the TWAIN source (i.e., to Nikon Scan). Con se quent ly, in the
Windows ver sion of Nikon Scan a default val ue of 2.2 is used
for main scan gamma when ev er Use ap pli ca tion gam ma
is se lect ed. Second, the ap pli ca tion must sup port gamma
transfer. If Use ap pli ca tion gam ma is se lect ed with a
Macintosh ap pli ca tion that does not sup port this fea ture,
Macintosh system gamma (1.8) will be used.

Color Management

The profi les used by the Nikon Color Management System
are specifi ed in the “Color Man age ment” category.

Use Nikon Color Management System

This option turns the Nikon Color Management System on
and off. Changes to this setting only take effect after Nikon
Scan has been quit and restarted.

When Nikon CMS Is On…

…images are processed to ensure consistent color re pro ­duc tion, as described in “How Nikon CMS Works” (

79).

Because color management profi les typically contain their
own settings for gamma, the controls in the Gamma tab are
dimmed and inactive.

When Nikon CMS Is Off…

…monitor and color-space profi les are not used, and the
con trols in the Color Management tab are dimmed and in­ ac tive. The only tool available for ensuring that colors from
the scan ner will be displayed accurately on the monitor is
the “Gamma” category (

82). The only adjustments made

to the image be fore it is passed to the host application are
gam ma ad just ment and changes to curves and color balance
made in the scan win dow.

The “Monitor” Tab

The “Monitor” tab specifi es the profi le that will be used
when images are displayed on your monitor, either in the
scan window preview area or a Nikon Scan image window.
Monitor profi les contain information about the color and
gam ma characteristics of the monitor, allowing images to be
ad just ed for more accurate color reproduction.

Use factory default monitor profi le (default)

Nikon Scan is supplied with default monitor profi les for use
when no other profi le is available (see below). To use the
default pro fi le for your plat form, select Use factory default
mon i tor pro fi le.

Default Windows Monitor Profi le (Gamma 2.2)

The default Windows monitor profi le (“NkMonitor_Win.icm”)
is identical to the sRGB profi le.

The “RGB” Tab

The “RGB” tab is used to select a color-space profi le for the
cal i brat ed RGB color model. The profi le used can be se lect ed
from the Color space menu.

Each of the pro fi les listed may be classifi ed according to its
gam ma value and gamut. Gamma is a fundamental char­ ac ter is tic of im ag ing systems which determines the intensity
of the output sig nal relative to the input; in human terms,
gamma controls the subjective brightness of images through
al ter ations to the out put level for mid-tones. Win dows
and Macintosh systems pro cess video signals dif fer ent ly,
and these differences are re fl ect ed in the difference in the
standard gam ma values for these plat forms. The default
system gamma for Macintosh computers is 1.8, the de facto
standard for Win dows systems, 2.2. Nikon CMS includes
eight RGB pro fi les with a Windows gamma of 2.2 (sRGB,
Bruce RGB, NTSC [1953], Adobe RGB [1988], CIE RGB, Wide
Gamut RGB, compensated Wide Gamut RGB, and Scanner
RGB), and three profi les with a gam ma val ue of 1.8 (Apple
RGB, ColorMatch RGB, and compensated Apple RGB), for
use on the Macintosh. When scan ning im ag es, choose a
profi le with a gam ma value suited to the sys tem on which
the image will be edited.

RGB Profi les Provided with Nikon Scan

Windows Profi les (Gamma 2.2)

sRGB

This RGB profi le is used in the majority of Windows mon­ i tors. It closely re sem bles the RGB commonly used in color
tele vi sion, and is also used in the digital tele vi sion broad­casting sys tem that is on its way to becoming the industry
standard in the United States of Amer i ca. Soft ware and
hardware man u fac tur ers use it as a default color profi le and
guarantee operation when it used. It is also on its way to
be com ing the standard for images on the web. This profi le
is suited to users who plan to use their digital images “as is,”
without editing or printing them. It however suffers from
the draw back of a narrow gamut with a limited area avail­able for re pro duc ing blues. The cor re spond ing RGB setting
in Photoshop 5.0 is “sRGB.”

Bruce RGB

This color profi le attempts to expand on the ColorMatch
RGB gamut by de fi n ing the chromaticity for G as lying be­tween the values for G in the Adobe RGB and ColorMatch
color-space pro fi les. It was pro posed by Bruce Fraser, who
claims that it in cludes most of the colors in the SWOP CMYK
gamut. It is not provided in the standard install of Photoshop

5.0, but can be selected as the RGB color-space profi le for
Photoshop by im port ing the profi le “NkBruce.icm”.

NTSC (1953)

This is the color space for video defi ned by the National
Tele vi sion Standards Committee (NTSC) in 1953 and used in
early color televisions. This color space is also used in some
Far-East newspaper and printing organizations. The cor re ­spond ing RGB set ting in Photoshop 5.0 is “NTSC (1953).”

Adobe RGB (1988)

A color-space profi le defi ned in Photoshop 5.0. It has a
wider gamut than sRGB and includes the colors found in
most CMYK gam uts, making it suitable for users involved in
desktop pub lish ing. The corresponding RGB setting in Pho ­toshop 5.0 is “A do be RGB (1988).”

CIE RGB

A video color-space profi le established by the CIE. While
it boasts a fairly wide gamut, it suffers from the drawback
that the area de vot ed to the re pro duc tion of cyan is relatively
small. The cor re spond ing RGB setting in Photoshop 5.0 is
“CIE RGB.”

Wide Gamut RGB

This color-space profi le, designed by Adobe, in cor po rates
most of the visible colors. This however has the con se quence
that most of the colors it can express can not be reproduced
on standard mon i tors and print ers. The corresponding RGB
set ting in Photoshop 5.0 is “Wide Gamut RGB.”

Preferences— Nikon Color Management

88

Wide Gamut RGB (compensated)

Nikon scanners can scan some colors that cannot be ex­ pressed using the Wide Gamut RGB color-space profi le.
The com pen sat ed Wide Gamut RGB profi le redefi nes Wide
Gamut RGB to include all the colors that can be output from
the scanner. Be cause many of the colors that can not be ex­pressed in Wide Gamut RGB occur in the blue por tion of the
gamut, the level of detail in the blue area has been greatly
increased (be cause the gamut has been expanded in a non­ lin ear fash ion to in cor po rate just those colors that could not
otherwise be ex pressed, it can not be rep re sent ed in chro­ ma tic i ty di a grams using a stan dard RGB triangle). As is the
case with Wide Gam ut RGB, most of the colors defi ned in
this profi le can not be re pro duced on mon i tors and print­ers. It is output to the host ap pli ca tion as Wide Gamut RGB.
When scanning images into Photoshop 5.0 using this profi le,
set the Photoshop RGB profi le to “Wide Gamut RGB.”

Scanner RGB

This profi le replicates the color space achieved when scan ning
with Nikon CMS off. Its main purpose is to allow the LCH
ed i tor and Unsharp Mask tools, which are not available when
Nikon CMS is off, to be used to edit the colors produced by
the scan ner. In order to pro duce the effect achieved by turn­ing Nikon CMS off, the mon i tor profi le is not used, nor is an
ICC profi le included with the image when it is opened in the
host ap pli ca tion.

89

Macintosh Profi les (Gamma 1.8)

Apple RGB

This profi le is used in desk-top publishing applications and
in Adobe Photoshop ver sions 4.0 or earlier, and is the typical
RGB profi le for Macintosh monitors. The corresponding RGB
set ting in Photoshop 5.0 is “Apple RGB.” This profi le is suit­ able for work ing with images dis played on the Macintosh.

ColorMatch RGB

The ColorMatch profi le is native to Radius PressView mon­ i tors. It has a wider gamut than Apple RGB, with a par tic u­ lar ly wide area devoted to the reproduction of blues. The
cor re spond ing RGB setting in Photoshop 5.0 is “Color Match
RGB.”

Apple RGB (compensated)

This profi le defi nes tristimulus (red, green, and blue) chro ma ­tic i ty as the intersection of the curve that marks the limits of
the visible gamut with lines drawn from the Apple RGB white
point and pass ing through the points that defi ne tri stimulus
chro ma tic i ty in the Apple RGB color-space profi le. This pro­fi le is unique in that it preserves the characteristics of Apple
RGB while al low ing more sat u rat ed colors. It is not pro vid ed
in the stan dard install of Photoshop 5.0, but can be selected
as the RGB color-space profi le for Photoshop by im port ing
the profi le “NKApple_CPS.icm”.

“Gamut”

In addition to gamma, profi les can be classifi ed according to
their gamut, or the range of colors that can be ex pressed us-
ing the profi le. Gamut is conventionally expressed by means
of chromaticity, a measure of color developed by the Com-
mission Internationale de l’Éclairage (CIE). The CIE system,
which is modeled on hu man color perception, maps the
physical wave lengths of light to three coordinates (known
as CIE X, Y, and Z) that give unique nu mer i cal ex pres sion
to the full range of color differences that can be per ceived
by hu mans. Chro ma tic i ty is a mea sure of col or from which
con sid er ations of bright ness have been fac tored out, giving
a two-co or di nate system.

In the chromaticity diagram at right, the complete gamut of
col ors visible to hu mans is in the area en closed by the green
line. The curved portion of the line gives the chro ma tic i ty
of “pure,” un mixed colors with wavelengths in the visible
spec trum of 380–780 nm. The blue end of the spectrum
(380 nm) is at the bot tom left corner, the red end of the
spectrum (780 nm) at the bot tom right corner. The straight
diagonal line con nect ing these two points rep re sents the dif­ fer ent shades of purple cre at ed by combining red and blue
light. The colors inside the area en closed by these lines are
created by mixing light of dif fer ent wave lengths.

No color profi le is capable of expressing the full range of col­ors visible to the human eye. The diagram below com pares
the gam ut of col ors vis i ble to the eye with the colors that can
be ex pressed in each of the RGB profi les pro vid ed with Nikon
CMS. The gamut for each profi le is con tained in the triangle
defi ned by the three points that mark the ex tremes of red,
green, and blue for that profi le (red is at the bot tom right
corner, green at the top of the triangle, and blue at the bot­tom left corner). The white point for each profi le is shown
by the symbol in the cen ter of the triangle.
