Hi, I finally got round to trying to calibrate my PJ at the weekend with Avia, but ran into problems with the Hue and Tint calibrations and wondered if anyone could help. They mentioned that you had to have a blue and red filter for these tests and there did not seem to be anyway of calibarting without these filters. Is this correct?? Is there a way of producing a filter easily or is this something that I would have to buy?? I also didn't seem to any other colour tests or did I miss them for setting R/B/G. thanks, Dave.
