Finally, I will not change the gamma and the levels, because I tried something and I understood !

I add scanlines on one of my picture, and when I observe, it was equivalent to the same picture with the gamma to 2.5 instead of 2.2.

So, I conclued that the scanlines from the CRT screen affected the gamma and the general luminosity of the picture. And it's not a question of levels.

A gamma of 2.2 on a CRT looks like a gamma of 2.5 on a modern display, because of the technology that it used.

The other problem is, that I shoud change the gamma for all my videos, and I don't think it's the good thing to do. It's better to calibrate a screen to a certain gamma rather than to change the gamma of videos.

And if Higan propose to have a color filter that we can activate or not, it's just for a certain representation of what the CRT were. It doesn't respond to an objective will.

Voilą ! J'ai tout dit !


(I know it's not exactly representative of the reality, but these pictures are just for the examples)
