Complete and Useful Function
■ TLCI (TELEVISION LIGHTING CONSISTENCY INDEX)
There five levels of TLCI for Studio luminaire
TLCI scores lights in five categories ranging from the poorest quality (<25) to the highest category (>85).
85 to 100 Errors are so small that a colorist would not consider correcting them. 75 to 85 A colorist would probably want to correct the color performance, but could easily get an acceptable result. 50 to 75 A colorist would certainly want to correct the errors, and could probably achieve an acceptable result, but it would take significant time to get there. 25 to 50 The color rendering is poor, and a good colorist would be needed to improve it, but the results would not be to broadcast standard. 0 to 25 The color rendering is bad, and a colorist would struggle for a long time to improve it, and even then the results may not be acceptable for broadcast.
■ TLMF (TELEVISION LUMINAIRE MATCHING FACTOR)
Television Lighting Matching Factor [TLMF] allows users to set the data of their preferable Fresnel or Flood Light as a reference by thyself. When users select the TLMF reference to be the benchmark, the Assessment Index, ColorChecker Chart, Colorists Advice, and Spectrum Reference will base on it to calculate.
■ Colorchecker Chart
Colorists, gaffers, and technicians may visually get the difference between the “Reference Light Source” and “Measurement Light Source.” As well as the Q value at the bottom of each color patch tells you the percentage of similarity between the “Reference” & “Measurement” light sources.
For example, if you want a reddish scene, but your measurement results as shown below, the red will color shift seriously, and people should take more time to adjust the color.
■ Advice for Colorists
This table shows the magnitude and direction of the corrections needed for lightness, chroma and hue, in each of 12 color sectors. The more + and – symbols, the worse the performance and the harder it is to correct.
BBC, NBC, CNN, Disney, and ITV, around the world to name a few, all recommend TV professionals to use TLCI for light standard. With the TLCI, colorists can handle their job faster on-site and studios can reduce the cost of post-production.
