Is calibration worth it? Definitely, if you have a good TV and want the best possible picture from it. I have a Panasonic ZT60, some say it is the best plasma screen ever and I was very pleased with the picture. However, after calibration the picture was even better. The changes were only subtle but now the shadows are deeper without being clogged and the highlights are brighter without being burnt out. The kitchen TV may have more initial impact but the image remains a TV image. Whereas the calibrated image on my ZT60 looks more real and believable. It is reassuring to know that the image is as good as it gets and shows what the director intended. The calibration session with Vincent was enjoyable and informative; he was very willing to explain what was happening and to show the 'before and after'. When I eventually get an OLED TV then I will be calling Vincent to calibrate it.
