When a camera is enhanced, it will move to a higher level, represented by stars.
The base features will obtain higher values. The previously randomized features and their respective values will remain unchanged.
Each time a camera is enhanced, it will receive a randomly chosen feature with a random value.
For example, if you want to enhance a level 2 camera to level 3, you will need an additional 4 level 2 cameras (excluding the camera being enhanced).
The features of the cameras used for enhancement have no influence on the resulting enhanced camera. You can only enhance a camera with other cameras of the same level and for the same nature park.
