Hi. Look this video I shared some time ago: http://www.youtube.com/watch?v=9PebBQOpP3I and read the description. You can also read there: //www.freelists.org/post/argyllcms/Reading-an-i1Pro-chart-with-ColorMunki (and following posts) to have an idea of what results you can get from the readings. If you search here: //www.freelists.org/archive/argyllcms you will find a lot of info about ColorMunki Photo. It is a good device to start in my opinion. I own the ColorMunki and the i1Pro and I made a comprason here: http://www.luminous-landscape.com/forum/index.php?topic=50214.0 You can read more here: http://www.luminous-landscape.com/forum/index.php?topic=57507.0 A good profile is not only good readings. No software will give you the best result if you don't study it and to have good results you may need not only a good number of patches but also a good general knowledge of color management.
