[edit] sRGB

$V'_{sRGB} = \begin{cases} \ {12.92L} ;& 0 \le L \le 0.0031308\\ \\ {1.055L} ^ {\left ( \frac{1}{2.4} \right )} - 0.055 ;& 0.0031308 < L \le 1 \\ \end{cases}$

[edit] Rec. 709

$L = \begin{cases} \dfrac {E'_{709}} {4.5} & E'_{709} \leqslant 0.081\\ \\ \dfrac {E'_{709} + 0.099}{1.099} ^ {\left ( \frac{1}{0.45} \right )} &, 0.081 \leqslant E'_{709} \\ \end{cases}$
