I understand your use of the lab color space for information, not necesarilly actual adjustments.

I use an Apple Mac system.

One of the more useful features is the DigitalColor Meter.
This useful program can be set to open automatically, with it you can measure L*a*b values from any program that your system can display i.e. all browsers, any imaging program, email attachments etc.etc..

I know nothing of the Windows operating system, but it should have something similar, and similarly useful.

As an aside "Raw Developer" a Mac only raw developer program can display L*a*b values and also allows you to make adjustments in L*a*b.

DigitalColor Meter used to be a reliable way of finding out what RGB values were being sent to the video card, and to the display. That’s about it. That doesn’t tell you about the data in the document.

The read outs seem to match well with the Photoshop info panel when checking lab values.

I've never used if to for RGB values.

What’s wrong with this picture?



And under Lion, no way I see to get Lab values. Considering the readings are based on what is spit out from the video system to the display, probably a good thing.
