Description

The Asensetek Lighting Passport Standard Spectrometer is perfect for fast, accurate selection and adjustment of film and studio lighting

  • Reduce time to set studio lighting
  • Minimise post-processing
  • Comply with Television Lighting Consistency Index (TLCI)

The TLCI metric (Television Lighting Consistency Index) was developed to address the shortcomings of traditional CRI measurement techniques.  Because cameras interpret light differently to how the human eye perceives it, the TLCI provides a more accurate prediction of the colour rendering characteristics of film and studio lighting.

The Spectrum Genius Studio (SGS) APP for iPad provides users with the ability to get all the TLCI information easily and quickly.  When used with the Lighting Passport Spectrometer, “Spectrum Genius Studio (SGS)” allows professionals such as producers, colourists, gaffers, and technicians to get full and detailed information about the TLCI of a specific light source or the entire set up.

What is the Television Lighting Consistency Index (TLCI) metric?

The TLCI value is an index on a 0-100 scale that is a composite of multiple parameters.  Television and film studio production often adopts a TLCI > 90 as a minimum starting point, providing cinematographers and gaffers a fast, accurate method to quantify lighting and avoid spending a lot of time and effort on extensive testing while minimising the amount of post-processing required.

Simply select TLCI as the reference standard and SGS will compare your measured light source with the TLCI Standard values and tell you how much your measured light differs from the Standard.

In addition to TLCI, the “Spectrum Genius Studio (SGS)” APP also provides several other useful parameters such as CRI, CQS, and CCT.
