The shaking camera is caused by socalled floating point accuracy:
In real-time 3D graphics, the position of an object is specified by 8 digits for each axis, e.g.:
X = 180.90123
Y = 43.143467
Z = 1427.7927
The laptop in your scene was placed at xyz (350.xxxxx, 10.xxxxxx, 350.xxxxx).
The further away objects are from 0,0,0, the more jittery they and the camera become since there are fewer digits after the comma to ensure accuracy. This may not sound like much, but if you placed the laptop, say 4000m from the world origin, the camera shake would be even worse. Obviously you couldn't possibly know this since Lumion currently doesn't display the position of objects.
In the upcoming SP2 Build 8, however, Ferry has made it possible to see what the position of the currently selected object is, provided that Settings -> "Show Frames per Second" is switched on. If you move the laptop to a position close to 0,0,0, the camera (and the laptop) won't shake anymore.
This should make it possible to render close-ups /product visualisations without problems in the future.
