Complete and Useful Function
■ TLCI
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).

85~100 Errors are so small that a colorist would not consider correcting them.
75~85 A colorist would probably want to correct the color performance, but could easily get an acceptable result.
50~75 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.
25~50 The color rendering is poor, and a good colorist would be needed to improve it, but the results would not be to broadcast standard.
0~25 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.
Use “Spectrum Genius Studio (Tablet)” together with the world’s first spectrometer─ Lighting Passport, every professional in TV, and Broadcasting, and Film-making Industry can get the best user experience.
