I like the two layers in this photo! The one outside, the "reality" of the photograph and the one reflected inside the glass! The reflected one is what gives a "narrative", a meaning to the picture, but it is actually just a "reflection" of reality! It's just a fake, inaccessible reality... It's like an "idol", or a dream.. Its just an inaccessible version of reality, that somehow has more meaning than the reality itself. On the other hand, the whole photograph as an item, is also a "reflection" of reality.. So the image then acquires a third layer, that of the reality of the viewer.
So "Semiotically" is a very interesting work!
I know, I'm over analyzing it, but.. never mind, that's how I understand it!
