Wide Gamut RGB - The primaries are the pure wavelengths of red, green and blue light. This space has a hugh gamut
and will cause 24-bit files to fall apart due to posterization, particularly in the light greens. For adventurous folks who use
a wide-gamut, 48-bit capture device, it may be a useful tool.
Simplified Monitor RGB - This is basically your monitor ICC profile. Think of it as the ―work like Photoshop 4.0‖
option. Unlike all the other spaces offered, this one isn’t device-independent, because it’s tied directly to your specific
monitor – it will be different on someone else’s monitor.
Click on SAVE and give the ―profile‖ that you have just created a name. In my example to the right, I have called my
settings DCN_SETTINGS. Then click on SAVE.
That will take you back to the previous COLOR
SETTINGS set-up window where you can click on
OK to close it. This completes the settings that you
need to make within Photoshop.
At this point, you have adjusted your monitor to
deliver a good neutral performance for color; you
have told Photoshop what color space (ColorMatch
RGB) you will be using, and you have told
Photoshop what to do if you attempt to open an
image file that does not match the gamma of the
color working-space… namely, it is to ask you what
to do, and you will then, usually, tell it to convert the
image to the RGB working space (which is now set
to ColorMatch RGB).
Now it is time to make some test prints, and perform a little fine-tune tweaking of the printer drivers.
In Photoshop, OPEN the .psd image (on the CD-ROM that you received from us) called ―Calibration_Image_1”. If you
are asked by Adobe if you want to ―convert‖ the image that you are opening. Answer ―Yes‖ and let Adobe ―convert‖ the
image to ColorMatch RGB.
The test image, Calibration_Image_1 should appear to be a nearly correct B&W image of a small child. It may appear
slightly too dark or slightly too light. If it is only slightly in error, correct it by re-setting the Adobe Gamma settings. The
Adobe Gamma settings are found by going to CONTROL PANEL > ADOBE GAMMA. If it is grossly in error, go back
to the start of these instructions and start all over – you’ve done something very wrong.
