   Right, I just heard overnight that they get color pictures by taking   
   sussessive exposures using filters of different colors. But if there is   
   noticeable motion at the time of the exposures, then you can't get a clear   
   picture with that approach, so they just go with a monochrome image. (BTW   
   that single "color" could be white, or infrared, or UV or a number of other   
   possibilities.

   Me too, but unfortunately, while Titan is probably going to be the most   
   colorful object on the whole tour, don't expect color pictures on this early   
   flyby--for exactly the reasons just described. A flyby is going to have too   
   much motion to get three successive exposures that match up.
