As for time to calibrate will depend on what it is that requires calibration. For example a TV will take less time generally than a projector. That’s from what I understand so far. Being that the course is very hands on I’m sure I will know alot more upon completion.
As for gear I will be trying out different Meters and Generators throughout the course. At the moment I will be looking at purchasing the ChromaPure THX Pro software and a Murideo Generator with X-Rite Pro D3 Meter and i1Pro2 spectroradiometer. This has been recommended as a good starting point by Gregg at THX.
Hope I have answered your questions adequately mate. I am sure I will know alot more upon completion of the course.
