Spyder3Elite Tools ~~ Colorimeter

Spyder3Elite Tools ~~ Colorimeter

2008-02-08 by PJS

As I can find no help for this subject, either here or at the 
Datacolor Knowledgebase, could you please explain what can be done with 
this function? Is it only for reading preset colors from the boxes on-
screen? Is there a way to directly from the monitor, for instance a 
full screen photo of the GretagMacbeth Color Rendition Chart? And did I 
miss the "help" section for this? I could find no information on any of 
the "tools" functions.

the sentence:

should read

Is there a way to directly MEASURE from the monitor, for instance a 
full screen photo of the GretagMacbeth Color Rendition Chart?

The colorimeter window allows you to create any RGB color mix on screen, and measure it, getting XYZ, etc... colorimetric values back. You can measure any flat color patch on screen (not much logic to measuring non-flat color values), just pay attention to what type of color management is involved, if the patch is not actually in the colorimeter window. After all, an "AbobeRGB" color patch will be converted on the fly to your display profile, if you measure it in Photoshop, so the RGB values the eyedropper will give you are NOT the ones the screen is presenting to the colorimeter.
