Setting up the final design

I really want my photography to compliment my final design; I want the contrast between the paper and the backdrop to be as high as possible. Unfortunately I do not have a black backdrop, so I have already decided that I am going to edit this later on in photoshop. Therefore I need to ensure that the paper is completely white in all of my photographs so it will be easier to distinguish from the background later on in PS.

Here I am experimenting with various layouts; as the brief states that the poster format must be portrait, I have decided that the poster would work best with the objects stacked vertically reading '100' down the page.
