This was just a flyby. To get as many pictures as you can get, you
wouldn't want to have to screw with all the filters it would take to get

mission.

I'm pretty sure this fly-by used all the filters.
Exposure time for each photo certainly didn't need to be much given the
level of illumination provided by the Sun.
