I started the documentation creating oppositional pairs using both the "X" and "z" letters, however, I realized today in our process critique that it was only contrast photographs of the 12" object. I took more photos today that fulfilled the requirements. I would really appreciate comments on the pairs (there are 4 required sets but I attempted all of the given relationships)! The variable is listed under the photograph. (Obviously, there are quite a few photos that will be edited with Photoshop but I wanted to just put the shots up for feedback before I edit details in each one).
