Setting up the Scene (Image 1)

Before I could start bringing any of my modelled components into my photographs I needed to set the camera up with the photo attached to it. I then needed to make sure the perspective was working with the photograph by adjusting the placement of the grid and the focal length of the camera to make the photograph.
I have done this below for my first image. You can see that the previous ones are making the back of the test object too high or low in perspective whereas in the photograph the back seems level with the front.
