I noticed that within the Dronelink command "Camera Photo Type" the presence of both a High Resolution and a Smart parameter.
Further testing shows that the MA2 will successfully receive and execute commands with each parameter. The High Resolution instance modifies the shutter button to contain a "48MP". The Smart instance leaves the shutter button unchanged. Both will take a photo but need further testing to see if they actually do what they indicate!
The peculiar thing is when you select Menu, the Camera Mode immediately changes from Photo to Video. Also, there are no on-screen menu options depicted for either High Resolution or Smart as a capture option.
