Section 1: Introduction
MEASURED (MCGD) NOTES:
For each color, record the native uncorrected x/y color coordinates measured at the screen. These values simply
represent the
currently viewable
primary colors, and collectively (when saved) will define the raw color
performance reference point for this projector in the current environment. Each radio button activates the
corresponding full-field YCbCr test pattern of this native color so that measurements can be taken. For
example, to measure the red coordinates, click the
Red
radio button to change the screen display to full-field
red, and measure coordinates at the screen. Repeat for each color, and record them in the nearby
x/y
text boxes.
After all colors have been measured and recorded, select
Pattern Off
to leave the special test pattern mode. To
cancel changes and return to the previous MCGD coordinates, leave the menu without saving.
CREATE MCGD NOTES:
This button collects the current color values entered for Measured (MCGD), where you can save them as a new
OnSite MCGD file or as a different MCGD file with a
different
name. Note that a new OnSite overwrites any
previously defined OnSite file, and will be the
default
reference point for all future color processing-the old
OnSite file cannot be recovered. By default, the projector will refer to OnSite data to calculate the corrections
needed to achieve a known
target
color performance standard in the future. However, if the site requires more
than one set of native MCGD values (such as when an auxiliary lens is swapped in or out), you can create a
new MCGD file with a different file name. Each setup (channel) can then use any desired MCGD file as the
basis for the color corrections needed for a target color. MCGD files are chosen in the
Custom
menu.
NOTE:
Once created, user-created MCGD files can be deleted only by using Christie's licensed
DCP
Librarian
software.
Important!
Create MCGD
is a permanent over-write of any previous MCGD
OnSite
file, and will define new
default color processing in the projector.
TARGET (TCGD) and CREATE TCGD NOTES:
Upon opening the
Gamut
menu, the Target (TCGD) color fields show the corresponding x/y color coordinates
defined for the current target color gamut in use. You can create a new custom target by defining different
coordinates for one or more TCGD colors (or simply by changing the tolerance state), and saving as a new
TCGD file. Note, however, that industry-defined TCGD standards, such as P7v2 and others, are write-
protected and cannot be changed-modifications to such a target must be saved under a new TCGD filename
entirely. Once you have created a new TCGD file, it will appear in the
Custom
menu, where it can be selected
for use in the display.
NOTE:
For most applications, TCGD values are used simply to verify that displayed colors actually do match
the standard-i.e., you can measure each color at the screen and compare its coordinates to those appearing in
the TCGD fields to confirm that the projected colors are accurate. For special applications in which you want
to create a unique target color standard, enter new TCGD coordinates as desired, and then save as a new
TCGD file. Apply as usual from the
Custom
menu.
GAIN NOTES:
Gain indicates the luminance (a.k.a. brightness or intensity) of each color as compared to full-on white, ranging
from 0 (0%) to 2 (100%). You may want to modify one or more gain values to precisely match color levels in
other adjacent displays or to accommodate a studio's internal color management technique. Gain would rarely,
if ever, be adjusted for theatre use.
