Summary
DescriptionCiecam02 luminance level adaptation factor.svg | CIECAM02: log-log plot of luminance level adaptation factor. And its cube root approximation, versus the——luminance level of the "adapting field." The axes indicate the base 10 logarithm of the quantity, so LA ranges from 10——to 10, while FL ranges from 10——to 10. |

MATLAB Code
la=logspace(-4,4) k=1./(5*la+1) fl=k.^4.*la+0.1*(1-k.^4).^2.*(5*la).^(1/3) loglog(la,fl,la,0.1715*la.^(1/3)) set(gca,'XTickLabel',-4:2:4,'YTickLabel',-4:1)
If you are curious as to how I derived the 0.1715 coefficient, you need simply substitute la=1 to get k=1/6 and fl=0.1715.
