Re: Colorsync-users Digest, Vol 11, Issue 132
Displaying the values sent to the monitor is exactly what makes the digital color meter useful for trouble shooting and finding problems and inconstancies in “color managed” applications. If color management is working correctly in an application or between applications the same values will be sent to the screen from different input sources and from the same source through different applications. e.g. comparing how a web browser and photoshop display a tagged image. Just the other day I was using Lightroom 5 on a dual monitor set-up and wondering why the image displayed on the second screen in develop mode is darker than it is when opened in photoshop. Just my eyes playing tricks on me?? NO! Displayed values are lower as confirmed through digital color meter. Now as to why it does that???

'Classic Color Meter' is by Ricci Adams http://www.ricciadams.com/projects/classic-color-meter Its a tool that I find to be a very useful addition to Photoshop's eye dropper tool. I use it set to display color in Lab mostly.
But unless I'm misunderstandings, it's not doing things differently than the Apple product which will not necessarily agree with a color managed app as Chris suggests.
For me, the tool's only utility is for applications which lack their own numerical color readout. It's better than nothing and not all that bad, but it definitely has its limits.
For example, the ACR profile editor, last I worked with it, lacked a color readout. The least-worst ACR profiles I was able to create I made with the use of the Adams Classic Color Meter.
I can't imagine any advantage it might offer over the many different ways Photoshop offers to provide similar information.

If the display profiles defining the calbiration are not identical (and that's unlikely) wouldn't that throw the DigitalColor Meter analysis off? Also, in LR, you need to view the data in Develop at 1:1 (100%) while viewing the image that way in Photoshop. On the same display, they should appear the same. On differing displays, I suspect the calibration would be a huge factor here. Lastly, why not use a instrument? Presumably you used one to build the profile for both displays. I just don't as yet see anything that the DigitalColor Meter provides that is useful for color managed workflows. But I'm open to suggestions. Andrew Rodney http://www.digitaldog.net/
