As part of my #research since 2014 and teaching at the Mediadesign University of Applied Sciences, I integrate digital LEGO® models into filmed material. In this example, I filmed the background with an #iPhone 7 Plus. Additionally, I shot a matching #HDR image with the Insta360 One R. Then I tracked the camera with #Blender and integrated the model into the scene. The HDR image and additional sunlight provide a realistic look.
The process is not really complicated with modern applications. You just have to follow a specific #workflow. This requires patience and, of course, some experience with technical processes.
