What every coder should know about gamma
Um. Curiously, that first example didn't work for me. Figures 1 & 2, under "Light emission vs perceptual brightness" are compared thus: "On which image does the gradiation appear more even? It’s the second one!"<p>Except that for me it isn't. The first one, graded by emission rather than perception, appears more evenly graded to me. There is no setting I can find using the Apple calibration tool (even in expert mode) that does anything but strengthen this perception.<p>This raises only questions.  Is this discrepancy caused by my Apple Thunderbolt Display? By my mild myopia? The natural lighting? My high-protein diet? The jazz on the stereo? The NSA? Or do I really have a different perception of light intensity?<p>And is anyone else getting the same?<p>Note: I have always had trouble with gamma correction during game setup; there has never been a setting I liked. Typically there'll be a request to adjust gamma until a character disappears, but however I fiddle things it never does.
