what DO we see?

I made 4 photographs of different perspectives of the same piece of art by claudia matzko at the denver art museum "untitled (look)". I think claudia's piece was about how we see. I had told the contact lens fitting person just the day before that I wanted to make a series of photographs about how we see -- starting with what the world looks like to me without vision correction. I used a computer program to change the end result of each photograph. 1) uncorrected 2) do you see what I see? 3) do I see what you see? 4) what DO we see? I tried to choose my favorite of these, but I find that I cannot. People so far seem to respond most strongly to "do you see what I see?" and "what DO we see?". If anyone knows the artist, claudia matzko, I would love to be able to contact her. I would like ask her permission to display this as a derivative work.
