This image was a process in the making. I started off in Autodesk Revit with and existing desgin that I had for what I term as my conservatory building. I added all of the walkways and raised garden and pool beds. I also added Structural beams for the roof sections along with the roofs themselves. The remaining step was to add all of the railings.
From there I sent that resulting set of models in to Lumion 3D. I did all of the materials, environment, lighting, falling leaves, etc... I then used Lumion to render out a still frame. I used enhanced lighting effects in Lumion to simulate things like global illumination.
The the last step was a quick bath in Photoshop to add things like HDR Toning.
