    Correct name of L in HSL color model

    Alp Er Tunga Level 1

      In some writings L stands for lightness and in others L stands for luminosity ... even sometimes for luminance.

      Which one is correct?

      Which name is used for L in academic papers (or in the original paper defining HSL which I don't have) for the HSL color model?


      Additionally, independently from the above question ...

      Adobe uses luminosity for L in PDF reference and luminance in ACR ... and lightness in the HSL adjustment tab in Ps.

      Do these all refer to same HSL color model ... or they are referring to different things?
