WebThe idea of gamma correction is to apply the inverse of the monitor's gamma to the final output color before displaying to the monitor. Looking back at the gamma curve graph earlier this chapter we see another dashed line that is the inverse of the monitor's gamma curve. We multiply each of the linear output colors by this inverse gamma curve ...
