MATLAB – REC.709 OETF Plot

This is some simple MATLAB code that uses the Academy and SMPTE standardized information to plot an accurate and easy to visualize example of the ITU-R REC.709 OETF function (opto electronic transfer function). This was written in MathWorks Matlab.

Running this script in the Matlab IDE spawns a figure with the correctly plotted OETF function.

Knowing the response of this function is incredibly helpful in camera response testing and image processing that requires the response function of a particular color standard to be known.
