First of all, I am not upset in any way. I love the community and somehow I was a bit shocked but at the same time I was laughing but in a good sense.
It seems that the asker made some implicit assumptions on the application
Yes, I did. The assumption is that I am asking for the Graphic Design forum, not in yahoo answers. I wrote an example of the glass, just in case, someone thought it has nothing to do with images.
I now understand tho, that at first glimpse when people see "encoding" think on software, but that is precisely the reason I posted this question. We need to rethink that graphic design is more than clicking buttons, it is a complex process, it is a communication one.
And yes, it is regarding the theoretical framework. In this era of "Do it yourself" when people use PhotoImUsingItToDoAnithingShop the theoretical framework is needed.
Regarding the edit. I posted on a comment, that is actually a different question, but I like the way it is now... (I will probably update the image tho) so it is ok for me as it is now.
But a warning... there is a chance... I will post a modified version of my original question. Muahaha.
