Like the subject asks. I have an old i1 Display 2 lying around and HCFR got quite a few updates since the old Curtpalme guide. However the later guide wants you to go out and buy Chromapure and I would probably need to get a new i1 too. I know these old colorimeters can go a little out of wack (but not that much surely?) and I would only be able to do 2 point manual LCD white balance. But do you think I could get in the ball park? I don't need it to be perfect just close. Otherwise it's an expensive calibration from a pro or buying and learning the new stuff.
