Hi Graeme, Thanks for your speedy response. The method you suggested works well, and is way faster than mucking around with Excel. Cheers, Steven -----Original Message----- From: argyllcms-bounce@xxxxxxxxxxxxx [mailto:argyllcms-bounce@xxxxxxxxxxxxx] On Behalf Of Graeme Gill Sent: 03 June 2011 06:53 To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Re: scanin to compare before/after results of camera upgrade ... Here's a suggested method: Create a profile from one of your .ti3 files. rename your two .ti3 files to .ti1, and edit them to change the first line to CTI1, and change the COLOR_REP value to "RGB". Use fakeread to turn your two .ti1 files into .ti3 files using the profile you created above. This converts your RGB values to CIE values using the profile for one of the devices. Use verify on the resulting .ti3 files. Graeme Gill. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
