Nettet1. des. 2013 · To do this, a linear light value is raised to the power of 0.455, and to get that sRGB value back to a linear space, then we raise it to the inverse, i.e. ^1/0.455 otherwise known as ^2.2. The use of the matrixes must be done in linear space. but after transiting the matrix, you need to apply the trc or "gamma" encoding. Nettet0.5^ (1 / 2.2) = ~0.73 * 255 = 186 This is the equation for getting a linear space value (0.5) converted to a gamma space rgb value (186) I am having trouble doing the opposite. What I want to do is convert a RGB value in Gamma space into a 0-1 linear value Does anyone know what the formula is? Thanks in advance. Cheers. Offline / Send Message
