colour.models.ootf_reverse_BT2100_PQ(F_D)

Defines Recommendation ITU-R BT.2100 Reference PQ reverse opto-optical transfer function (OOTF / OOCF).

Parameters:F_D (numeric or array_like) – \(F_D\) is the luminance of a displayed linear component (\(R_D\), \(G_D\), \(B_D\); \(Y_D\); or \(I_D\)). Returns:\(E = {R_S, G_S, B_S; Y_S; or I_S}\) is the signal determined by scene light and scaled by camera exposure. The values \(E\), \(R_S\), \(G_S\), \(B_S\), \(Y_S\), \(I_S\) are in the range [0, 1]. Return type:numeric or ndarray
