Hi All,



I have a interesting issue where we have to set and keep the brightness setting of a set of photography iMac's.



I have to set the luminance of the screen to 120 so as to make the iMac's confirm to some working ISO standard for photographers, which the users cannot change!



Does anyone have any idea what plist/value i need to set to achieve this? I have been looking online for 2 days straight now and still have had no luck finding any help.



Help!

I'm not familiar enough to know how to set the exact luminance, but this command line tool called brightness seems to work really well for setting the brightness.

He has a precompiled binary at the bottom:

Once you've got it downloaded, it's really simple:



/path/to/brightness 1


Sets the brightness all the way up, and 



/path/to/brightness .5


Sets it at 50%.



Hope this can help!

Cheers Zach! this is definitely a step in the right direction! I'm sure i'll be able to extract a plan of work from this scrip!



Now i just need to figure out how to set a color display profile on a per user bases! any ideas welcome!

I am currently trying to set the color profile via this command;



defaults -currentHost write -g 1 -string "/Library/ColorSync/Profiles/<file name>"



I am trying to change this entry



<key>com.apple.ColorSync.Devices</key>
<dict>
<key>Device.mntr.00000610-0000-A00C-0000-000004280300</key>
<dict>
<key>CustomProfiles</key>
<dict>
<key>1</key>
<string>/Library/ColorSync/Profiles/iMac Calibrated.icc</string>
</dict>
</dict>
</dict>



Does anyone have any idea's on why the default write isn't working and is instead just amending a line with a new key called 1 + the color profile? :-/
