Word of mouth introduced me to a program called Sibl Gui. The program is focused on creating an image-based light set up using HDR images. It can be plugged into many 3D softwares such as Maya.
Using this software, I investigated and tested IBL set ups to see the impact that image-based lighting can have on the integration of CG elements in live-action environments.

Using HDRs downloaded from the Sibl Archive online as environments, I created sphere's with specific shaders - one a chrome ball to test reflections and the other a lambert, to see the effect that IBLs have on indirect lighting.
I then used this software to test my own IBL of the DJCAD entrance.
This is an image of the same spheres, as seen above, without the reflection and indirect light applied to them from the IBL. They have not, in any way, been lit at all; I am only using Maya's default light in this example.
This is a comparison displaying the IBL being applied to the sphere's in both reflection (chrome) and indirect light (lambert) and we can see that their is a significant difference in the integration of the CG elements with the photographed environment.
After this test, I realised that I had not actually centered the horizon line of my panorama and so the image is slanted. This is a minor issue and is very easily fixed and so I will likely tweak this test whenever I get the chance.
