ISF is just a name for an organistion. ISF calibration is really just calibration to the international TV standards...those are laid down by EBU and SMPTE amongst others. Adherence to the TV standards will give you a more accurate image. If you don't like an accurate image then that's cool too. |
Just to update this information from Gordon.
THX now run calibration training for all display types and you will soon see Calibrators in the UK displaying the THX badge for passing their training course and stringent exam. The THX examination is based on actual calibrations the calibrator does, so there is some quality control to ensure the professional guys can put their skills into practice. THX calibrators have to be tech 1 trained before they can go on the calibrators course as well. This training is very similar to what ISF do.
THX also introduced the certification programme in the UK with JVC, LG and Panasonic products. This means that the THX picture preset in the menu system is factory calibrated to try and get close to D65 and ITU-r.709 standard. Obviously its impossible for a factory calibration to take in to account sources and environment of the display, but its a good starting point. It is encouraging that this preset is being made available and should give people a better idea of what an accurate image can look like. ISFccc on a TV does not give the user any picture preset, it is basically a display that has a certain amount of flexibility of settings for ISF professionals and offers day and night locked menu selections once the TV has been professionally calibrated.
