HDR is very important when working on the base of light, reflection and refraction. I would say that today there is no other way to start if you are making real footage and using 3D elements. Rosie is fully reflective, and there are some close-ups, so in the model, I didn't use a chrome ball. We did a panorama, and ended up with a really high-res HDR for all the scenes.
In V-Ray, you'll find a map node called VRayHDRI, where you can load the HDRI file. This map allows you to choose the type of HDR you are loading; in my case it was a Spherical mapping. When it was loaded, I then adjusted the position of the HDRI in the viewport.
Normally in 3ds Max you'll put your map in the Environment map slot, but with VRayHDRI you have a better result and it's easier to adjust. There is also the bitmap standard in 3ds Max, but I would advise that you only load files with HDRI VRayHDRI, as again, it is easy to adjust.
Working with HDR
I start the lighting with V-Ray dome light using a HDRI map. Usually I start with the HDRI and add an area light according to the environment. Here, I lowered the intensity of the Dome light and used ‘Spherical' (full dome). With this option I used HDRI as a full sphere.
I wanted to create a hotter and stronger illumination, so I added very intense area lights from behind, creating an almost silhouette back light. I used a 3900k temperature – though some areas needed to be colder, and others lit from the side.
The picture here shows how the environment affected the lighting. First, I looked at the main light source (green lines) and tried to reproduce it. Secondly, I added other area lights to fill the darker points (red lines). Third, I looked to the shadow angles and blurs (blue lines). A good illumination of the model is very important, but sometimes this is not sufficient enough to integrate the model with the real scene.

Working with the environment
I tried to model some objects for the scene in order to integrate Rosie better with the environment. The more details you create the more you will have in your render.
