  Origin of terms “gamma” and “alpha channel”??

  Posted by Zafer Mustafa on July 3, 2008 at 7:00 pm

  Greetings from Boston!!!

  Purely for my own edification, I’m trying to find the history behind two terms we all seem to use all the time: gamma and alpha channel.

  Does anyone know where these terms came from and what their history is?? Was Gamma purely a math variable??

  I would be uber grateful for any leads 🙂

  much thanks and a great 4th to those of you in the States.

  Might be worth doing a search on “Alpha channels” in the Wikipedia. Think they have something on it there.

  Cheers
