luminance_Fairchild2010
(L_hdr, epsilon=1.836)[source]¶ Computes luminance \(Y\) of given Lightness \(L_{hdr}\) using Fairchild and Wyble (2010) method according to Michealis-Menten kinetics.
- Parameters
L_hdr (array_like) – Lightness \(L_{hdr}\).
epsilon (numeric or array_like, optional) – \(\epsilon\) exponent.
- Returns
luminance \(Y\).
- Return type
array_like
Warning
