The OOTF maps relative scene linear light to display linear light.
- Parameters
E (numeric or array_like) – \(E = {R_S, G_S, B_S; Y_S; or I_S}\) is the signal determined by scene light and scaled by camera exposure.
- Returns
\(F_D\) is the luminance of a displayed linear component (\(R_D\), \(G_D\), \(B_D\); \(Y_D\); or \(I_D\)).
- Return type
numeric or ndarray
